Background
Lupus erythematosus is an autoimmune disorder striking every organ system. Its many presentations can mimic many diseases. This disease requires close cooperation between the treating physician and the pathologist. The systemic disease, known as Systemic Lupus Erythematosus (SLE) can be diagnosed with 4 or more of the 11 criteria below, either serially or simultaneously, during any interval of observation. In general, arthritis and joint complaints comprise the majority of initial signs and symptoms but ultimately 80% of patients will present with skin manifestations.
Patients may be treated with corticosteroids and immunosuppressive agents. However, these patients are immunocompromised and infections are common. Death is usually secondary to infectious complications, renal failure, or central nervous system disease.
The story of lupus does not end here. There are several well-established variants, such as Discoid Lupus Erythematosus (DLE), that involve selected organ systems and present with different ANA patterns. The outline below describes some of these important clinical variants.

One explanation for the increased incidence of the disease in women may relate to the fact women are hypomethylators of DNAHypomethylation of DNA correlates with increased biologic activity of lymphocytes and is the postulated mechanism of induction of drug-induced LE with certain classical agents such as hydralazine

The authors describe the case of a young Brazilian woman who was treated of ileocolonic Crohn's disease sparing rectum, as confirmed by colonoscopy and histopathological examination.
After a 4-year course of sulfasalazine treatment, she presented with skin facial lesions in vespertilio, fever, arthralgias and high titers of anti-ANA and LE cells. A sulfasalazine-induced lupus syndrome was diagnosed, because after sulfasalazine withdrawal and a short course of prednisone, the clinical symptoms disappeared and the laboratory tests returned to normal. Mesalazine 3 g/day was started and the patient remained well for the next 3 years, when she was again admitted with fever, weakness, arthralgias, diplopy, strabismus and hypoaesthesia in both hands and feet, microhematuria, haematic casts, hypocomplementemia and high titers of autoimmune antibodies.
A diagnosis of associated systemic lupus erythematosus was made. Although a pulsotherapy with methylprednisolone was started, no improvement was noticed. A cyclophosphamide trial was tried and again no positive results occurred. The patient evolved to severe clinical manifestations of general vasculitis affecting the central and peripheral nervous system and lungs, having a fatal evolution after 2 weeks.
Although uncommon, the association of both disease may occur, and the authors call attention to this possibility, making a brief review of literature.
EPSTEIN-BARR VIRUS Systemic lupus erythematosus in adults is associated with previous Epstein-Barr virus exposure.

OBJECTIVE: The possible molecular mimicry of the Epstein-Barr virus (EBV) peptide PPPGRRP by the peptide PPPGMRPP from Sm B'/B of the human spliceosome is consistent with the possibility that EBV infection is related to the origin of systemic lupus erythematosus (SLE) in some patients. Association of EBV exposure with SLE was therefore tested for and subsequently found in children and adolescents (odds ratio [OR] 49.9, 95% confidence interval [95% CI] 9.3-1,025, P < 10(-11)). These results were confirmed at the level of EBV DNA (OR > 10, 95% CI 2.53-infinity, P < 0.002). Much smaller seroconversion rate differences were found against 4 other herpes viruses. Herein, we extend these studies to adults and test the hypothesis that EBV infection is associated with adult SLE.
METHODS: We selected 196 antinuclear antibody-positive adult SLE patients (age > or =20 years) and 2 age-, race-, and sex-matched controls per patient. SLE patients and matched controls were tested for evidence of previous infection with EBV, cytomegalovirus (CMV), herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), or varicella-zoster virus (VZV) by standardized enzyme-linked immunosorbent assays.
RESULTS: Of the 196 lupus patients tested, all but 1 had been exposed to EBV, while 22 of the 392 controls did not have antibodies consistent with previous EBV exposure (OR 9.35, 95% CI 1.45-infinity, P = 0.014). No differences were observed between SLE patients and controls in the seroconversion rate against CMV, HSV-2, or VZV.
CONCLUSION: These new data from adults, along with the many suggestive features of EBV infection, are consistent with the contribution of this infection to the etiology of SLE.

We report a 9-year follow-up of a girl with systemic lupus erythematosus (SLE) and probable Sjogren's syndrome.
At the age of 7 years, the patient developed a chilblain-like eruption with features of SLE, including leucopenia, oral ulcers, positive rheumatoid and antinuclear antibodies and positive anti-dsDNA, anti-Ro/SSA and anti-La/SSB antibodies.
At the age of 13 years she developed Guillain-Barre syndrome, which completely resolved with aggressive treatment, including high-dose corticosteroids and the use of plasma exchange followed by intravenous gammaglobulin.
M ID-DERMAL ELASTOLYSIS Middermal Elastolysis in Two Patients With Lupus Erythematosus
Alan S. Boyd, etal.
Am J Dermatopathol 2001;23:136-138
Despite lupus erythematosus (LE) being considered a ``connective tissue disease,'' little has been written about the elastic fiber changes in the skin of affected patients.
We report our histologic findings in two patients with unusual cutaneous lesions. Elastic fiber loss was noted, and scattered giant cells with elastic fiber phagocytosis were prominent in one patient. The findings are similar to those described for middermal elastolysis. Other authors have reported patients with LE and elastic fiber loss resembling anetoderma.
We believe that a spectrum of elastic fiber changes can occur in patients with LE and may be induced by infiltrating lymphocytes and/or circulating antibodies.

J Am Acad Dermatol 1998 Apr;38(4):569-73 Abstract quote
BACKGROUND: Lupus erythematosus (LE) and porphyria cutanea tarda (PCT) may have similar clinical presentations, and their coexistence presents special problems in diagnosis and management.
OBJECTIVE: The purposes of this study were to describe a patient with discoid LE and PCT and to present a review of 15 patients with coexistent LE (all variants) and PCT.
METHODS: The medical records of all patients with coexistent LE and PCT seen between 1976 and 1995 were retrospectively reviewed.
RESULTS: Of 6179 cases of LE and 676 cases of porphyria (all variants), there were 15 patients, 6 men and 9 women, with coexistent LE and PCT. The mean age at diagnosis of LE was 42.8 years and of PCT was 48 years. Nine patients had discoid LE; five patients had systemic LE, and one patient had subacute cutaneous LE. The initial diagnosis was LE in eight patients, PCT in five patients, and simultaneous LE and PCT in two patients. Precipitating factors for PCT included alcohol in seven patients, iron overload in one patient, and estrogen in one patient. Treatment of LE with hydroxychloroquine 200 mg daily precipitated PCT in two patients. Patients were treated with phlebotomy or low-dose antimalarials for PCT. Patients with systemic LE received systemic glucocorticoid therapy. Patients with discoid LE and subacute cutaneous LE were treated with topical glucocorticoids.
CONCLUSION: The association of LE and PCT poses therapeutic challenges. The preferred treatment for one may exacerbate the other. Use of standard dose antimalarials for LE is inadvisable, and phlebotomy or low-dose antimalarials should be used cautiously in patients with coexistent disease.

Lupus-associated toxic epidermal necrolysis: A novel manifestation of lupus?Mandelcorn R, Shear NH.
Division of Dermatology, Department of Medicine, University of Toronto.
J Am Acad Dermatol 2003 Apr;48(4):525-9 Abstract quote BACKGROUND: Toxic epidermal necrolysis is an acute mucocutaneous reaction characterized by extensive cutaneous and mucosal sloughing and systemic involvement. It is generally associated with drug ingestion.
Objective and Methods: We describe 2 patients who developed typical clinical and histopathologic features of toxic epidermal necrolysis with unusual subacute progression, absence of systemic involvement or high-risk drug ingestion, and features of lupus erythematosus.
CONCLUSION: We propose that this constellation of features represents a new entity not previously described. This entity may represent a more severe variant of Rowell's syndrome or, alternatively, a novel manifestation of lupus erythematosus
PATHOGENESIS CHARACTERIZATION SLE GENERAL
- Activation/inactivation of the classical pathway of complement in non-lesional skin of patients with systemic lupus erythematosus.

J Cutan Pathol. 2005 Sep;32(8):537-40. Abstract quote
Background: The link between the lupus band and pathogenesis remains controversial, because immunoglobulins and complement components, including the membrane attack complex, can be found in both lesional and non-lesional skin of patients with systemic lupus erythematosus (SLE). The expression of proteins that regulate complement has not been previously investigated in the skin of patients with SLE.
Aim: The aim of this study is to compare the expression of protectin (CD59), which demonstrates the activation of the classical pathway of complement, in non-lesional skin obtained from patients with SLE with its expression in normal skin. This may help us explain the link between the lupus band and pathogenesis of cutaneous lupus erythematosus.
Methods: An indirect immunofluorescence technique was performed in order to provide unequivocal evidence for the activation of complement via the classical pathway and to compare the expression of CD59 in non-lesional skin from patients with SLE with normal skin samples obtained from healthy people. Results: The activation of the classical pathway of complement was demonstrated in non-lesional skin in more than 90% of SLE patients investigated in this study. Staining intensity of the complement regulatory protein CD59 was markedly increased in the majority of non-lesional skin samples obtained from patients with SLE, compared to that from normals.
Conclusions: CD59 is overexpressed in non-lesional skin in which complement activation has occurred. It seems likely that an increased and continuous CD59 expression may be important for maintaining the integrity of the skin BMZ during inflammatory responses involving complement activation in SLE skin.Molecular aspects in the pathogenesis of human systemic lupus erythematosus.

Systemic lupus erythematosus is a common and often devastating systemic autoimmune disease of unknown etiology.
In this communication we review the latest developments of the molecular pathogenesis of human lupus. Novel genetic studies of multiplex lupus families have revealed potential disease-associated genome intervals, put special emphasis on genetic loci mapping in the long arm of chromosome 1 and have underscored the complexity of the underlying genetic background. New data have emerged on the role of estrogens in the function of lymphocytes and a number of studies have recently emphasized the relative Th-1/Th-2 cytokine imbalance in favor of a Th-2 type cytokine immune response.
Finally, novel experiments have revealed an abnormal antigen receptor-mediated signaling process in lupus T and B cells, which may influence the aberrant expression and function of costimulatory molecules as well as of other aspects of immune cell function.
It is important to decipher the underlying molecular mechanisms that govern the expression of human lupus, because we may design novel, rational approaches in the treatment of a human lupus, a disease that has high morbidity and mortality.

Systemic lupus erythematosus (SLE) is a highly prevalent human autoimmune diseases that causes progressive glomerulonephritis, arthritis and an erythematoid rash. Mice deficient in deoxyribonuclease I (Dnase1) develop an SLE-like syndrome.
Here we describe two patients with a heterozygous nonsense mutation in exon 2 of DNASE1, decreased DNASE1 activity and an extremely high immunoglobulin G titer against nucleosomal antigens.
These data are consistent with the hypothesis that a direct connection exists between low activity of DNASE1 and progression of human SLE.

Under some conditions, UV light, viral infection, alteration of the calcium milieu, and estrogen exposure-Ro/SSA particles may be displaced from the nucleus to the cell surfaceMay explain the enhanced photosensitivity of skin and worsening symptomatology with calcium channel blockers and viral illness
Ro/SSA antigen is a 60 kDa protein attached to small RNAs to produce a 100 kDa complex with nuclear localization in normal adult skin
If insult such as UV, viral infection, or altered cytosolic calcium milieu occurs, Ro/SSA particles manifest upregulated or displaced expression from the nucleus to the cytosol and from the cytosol to the cell surface
This may explain the photosensitivity or photoreproduceability of skin lesions in anti-Ro/SSA positive LE patients and the worsening of disease symptoms in connective tissue disease patients experiencing viral illness

PURPOSE: We sought to identify the predictors of clinical outcome and of the evolution of cerebral abnormalities in patients with neuropsychiatric systemic lupus erythematosus (SLE).
SUBJECTS AND METHODS: Thirty-two patients with SLE (including 14 with the antiphospholipid syndrome) who had been hospitalized with primary neuropsychiatric disease were observed prospectively for at least 2 years. Laboratory and clinical characteristics and data from magnetic resonance imaging (MRI) studies obtained during the hospitalization and 2 years later were evaluated. We ascertained nonreversible or new MRI changes and clinical outcomes, including neuropsychiatric events, during follow-up.
RESULTS: Cranial MRI scans on admission were abnormal in 26 (81%) of the 32 patients. Patients with the antiphospholipid syndrome were more likely to have focal cerebral white matter lesions (odds ratio [OR] = 12, 95% confidence interval [CI]: 2.0 to 72). After 2 years, neuropsychiatric deficits substantially improved in 22 (69%) of the patients, stabilized in 6 (19%), and deteriorated in 4 (12%). The number of prior neuropsychiatric events was associated with persistent MRI lesions (OR = 4.8 per each event, 95% CI: 1.1 to 21) and unfavorable clinical outcome (OR = 4.3 per each event, 95% CI: 1.4 to 13) at 2 years. The antiphospholipid syndrome also predicted an unfavorable clinical outcome at 2 years (OR = 11, 95% CI: 1.7 to 65).
CONCLUSIONS: Among patients with SLE who have neuropsychiatric disease, prior neuropsychiatric events and the antiphospholipid syndrome increase the risk of adverse outcomes.

. We aimed to evaluate the presence of peripheral antineutrophil cytoplasmic antibodies (p-ANCA) and cytoplasmic antineutrophil cytoplasmic antibodies (c-ANCA) in children with SLE and to correlate its association of laboratory findings.
Twenty-one children with SLE were studied. Serum samples in patients were tested by indirect immunofluorescence (IIF) slide kit (INOVA) for c-ANCA and p-ANCA and by ELISA for myeloperoxidase (MPO-ANCA) and proteinase 3 (PR3-ANCA). All the patients but two were quiescent for lupus at the time of sampling. Sixteen of 21 patients showed positive IIF staining whereas only 5 had MPO-ANCA and 2 of nine PR3-ANCA.
The data suggests that SLE may be associated p-ANCA directed against additional target antigens rather than MPO and may be implicated in the pathogenesis of SLE or may be only non-specific antibodies developed in lupus.

OBJECTIVES: To evaluate, in a cohort of 566 patients with systemic lupus erythematosus (SLE) drawn from 11 European centres: (i) the prevalence of ANCAs and their subspecificities in a large series of European SLE patients; (ii) the possible associations of ANCA with the most common clinical manifestations of the disease; and (iii) whether ANCAs correlate with some of the autoantibodies commonly found in SLE.
METHODS: ANCA detection was performed by indirect immunofluorescence (IIF), and by ELISA for lactoferrin (LF), myeloperoxydase (MPO), proteinase3 (PR3) and lysozyme (LZ) subspecificities.
RESULTS: The prevalence of ANCA was 16.4% (IIF). The prevalence of LF was 14.3%, LZ 4.6%, MPO 9.3%, and PR3 1.7%. Our results show that ANCA is associated with certain clinical manifestations of SLE. In particular, positive correlations were found between IIF ANCA and serositis (p = 0.026), livedo reticularis (p = 0.01), venous thrombosis (p = 0.03) and arthritis (p = 0.04), while anti-LF antibodies were associated with serositis (p = 0.05) and livedo reticularis (p < 10(-3). Nevertheless, multivariate analysis demonstrated that other autoantibodies, such as aCL and SSA/Ro, are more closely correlated than ANCA with some of the aforementioned clinical features.
CONCLUSION: Our results demonstrate that ANCA are detectable in SLE sera and that some of them are associated with particular clinical manifestations. Whether ANCA plays a direct pathogenetic role in the vascular damage of SLE or only represents an epiphenomenon or a marker of disease activity remains to be elucidated.

OBJECTIVE: To examine the correlation between C-reactive protein (CRP) and CRP-inducing cytokines (IL-1 beta, IL-6, TNF-alpha) and IL-1 receptor antagonist (IL-1ra), as well as to study their relationship with systemic lupus erythematosus disease activity (SLEDAI) in newly diagnosed, untreated lupus patients.
METHODS: Sera from newly diagnosed untreated lupus and rheumatoid arthritis (RA) patients were examined for CRP and cytokines. Data were compared among patient groups and correlated individually among the lupus group. Lupus monocytes and neutrophils were cultured in vitro to produce IL-1ra and experimental results were related to CRP levels and SLEDAI.
RESULTS: Within lupus, serum CRP, IL-6, IL-1 beta and TNF-alpha levels were significantly lower than those of RA (all p values were < 0.005) and generally higher than those in the controls (p = 0.002, < 0.001, > 0.2, and < 0.001, respectively). Except IL-1ra, which was correlated with CRP (p = 0.045), no substantial correlation was discovered between CRP and IL-6, IL-1 beta or TNF-alpha individually. Moreover, excluding IL-1ra (p = 0.024), there was no association between cytokines and SLEDAI. In vitro IL-1ra as secreted by monocytes correlated with serum CRP and SLEDAI.
CONCLUSION: In lupus patients, serum IL-1 beta, IL-6 or TNF-alpha levels failed to correlate with low CRP levels. This indicates a complicated CRP production process, which can not be explained solely by single cytokines as reported previously. Both serum and in vitro produced IL-1ra may be applied clinically as a surrogate CRP marker in untreated lupus patients as they are both correlated with serum CRP.

Results of histologic examination of the skin and direct immunofluorescence analysis confirmed the diagnosis of systemic lupus erythematosus.
The distal matrix revealed changes suggestive of systemic lupus erythematosus accompanied by increased activity of melanocytes but without melanocytic hyperplasia. In this case, longitudinal melanonychia associated with systemic lupus erythematosus was of functional origin.

BACKGROUND: Red lunulae have only rarely been described in patients with lupus erythematosus.
OBJECTIVE: We assessed the frequency and classified the type of red lunulae in patients with definite lupus erythematosus seen in an interdisciplinary dermatorheumatologic outpatient clinic.
METHODS: We studied 56 patients with either systemic or cutaneous lupus erythematosus for the presence of red lunulae.
RESULTS: Eleven of 56 patients (19.6%) with lupus erythematosus had red lunulae. All of them showed a complete type of red lunulae, which was seen on all finger nails in 10 patients and on a single finger nail in 1 patient. Seven patients suffered from systemic lupus, the other from subacute cutaneous (n = 2) or chronic discoid cutaneous lupus (n = 2). There was no statistically significant difference in autoantibody expression or treatment regimen between patients with or without red lunulae. However, symptomatic patients had a shorter disease interval, and all but 1 showed either periungual erythema or chilblain lupus. Periungual erythema was not observed in any patient without red lunulae.
CONCLUSION: Red lunulae, although rarely described in the literature, are not an uncommon symptom of patients with lupus erythematosus. They seem to be associated with periungual erythema or chilblain lupus. Red lunulae should be considered in the clinical spectrum of lupus disease.

We present pathologic findings for 52 livers (51 autopsy specimens and one wedge biopsy specimen) from patients with systemic lupus erythematosus (SLE). Hepatic congestion was the most common disease (40 livers), followed by fatty liver (38), arteritis (11), cholestasis (nine), peliosis hepatis (six), chronic persistent hepatitis (six), nonspecific reactive hepatitis (five), cholangiolitis (four), nodular regenerative hyperplasia of the liver (three), and hemangioma (three). The data obtained here suggest that arteritis of the SLE liver is more common than has been recognized previously. One patient had hepatic infarction complications induced by arteritis.
On the basis of the findings in the present study and a review of the literature, we suggest that hepatic infarction resulting from arteritis is rare in SLE. On the other hand, while occurrence of nodular regenerative hyperplasia of the liver in SLE patients has been considered to be rare, our findings suggest that it may be more common than has been recognized previously. Although congestion and cholestasis may be acute terminal illnesses, fatty change is considered to be specific to the SLE liver. Statistical analysis indicates that exposure to a large dosage of glucocorticoids is a significant factor in the etiology of severe fatty liver.
In addition, our review of Japanese autopsy registry data for 1,468 patients with SLE indicates that the incidence of chronic liver diseases in SLE autopsy cases is as follows: chronic hepatitis, 2.4%; cirrhosis, 1.1%; and liver fibrosis, 0.8%.

Lupus 2000;9(2):140-3 Abstract quote
Lymphadenopathy (LAP) is a frequent sign of systemic lupus erythematosus (SLE). The lymph nodes are usually soft, nontender, varying in size from 0.5 cm to several centimeters. However, generalized LAP in SLE is extremely rare, while to our knowledge, the presentation of extensive LAP with blocks of retrosternal, mesenteric, and retroperitoneal nodes has not been previously reported as the first clinical manifestation of the disease.
In this report we describe a patient with extensive LAP and active SLE and we point out that generalized LAP should be included among the clinical findings indicating disease activity in SLE patients.

Background: Lupus erythematosus (LE) is a multifactorial autoimmune disease, which may affect the oral mucosa in either its cutaneous and systemic forms, with varied prevalence.
Methods: Forty-six patients with confirmed diagnosis of LE, presenting oral lesions were included in the study. Oral mucosal lesions were analyzed clinically, their histopathological features were investigated and inflammatory infiltrate constitution was assessed using immunohistochemistry against the following clusters of differentiation: CD3, CD4, CD8, CD20, CD68 and CD1a.
Results: From 46 patients with specific LE oral lesions 34 were females (25 with cutaneous LE and nine with systemic LE) and 12 were males (11 with cutaneous LE and one with systemic LE). Clinical aspects of lesions varied, and lips and buccal mucosa were the most affected sites. Histologically, lesions revealed lichenoid mucositis with perivascular infiltrate and thickening of basement membrane. Inflammatory infiltrate was predominantly composed by T lymphocytes of the CD4 subtype, with a minor prevalence of B lymphocytes, isolated macrophages and rare Langerhans cells.
Conclusions: Oral lesions of lupus erythematosus show a variety of clinical aspects and histologically consist of a lichenoid mucositis with deep inflammatory infiltrate, composed predominantly of T CD4 positive lymphocytes.

Background: Lupus erythematosus (LE) is an autoimmune disease of unknown cause. Prevalence of oral involvement in patients with LE is uncertain but may vary from 9 to 45% in patients with systemic disease and from 3 to 20% in patients with chronic cutaneous involvement.
Methods: Incidence of oral lesions of LE and their clinical aspects were investigated. Their histopathologic features were analyzed, and the status of epithelial maturation was assessed through the expression patterns of cytokeratins.
Results: Twenty-six patients (from 188 examined) presented oral lesions of LE. Most of them were females (19) with systemic disease (11). Clinical aspects of these lesions varied, and lips and buccal mucosa were most affected. Histologically, lesions revealed lichenoid mucositis with perivascular infiltrate and thickening of basement. Cytokeratins profile showed hyperproliferative epithelium, with expression of CK5/6, and CK14 on all epithelial layers, CK16 on all suprabasal layers and CK10 on prickle cell layers only.
Conclusions: Oral lesions of LE show a variety of aspects, and their microscopic features are of a lichenoid mucositis with deep inflammatory infiltrate. Cytokeratins expression patterns are of hyperproliferative epithelium, and this phenomenon must be analyzed in relation to the inflammatory cytokines for a better understanding of the mechanisms of the disease.PAROTID GLAND Periparotid lupus erythematosus panniculitis.

Lupus erythematosus (LE) panniculitis, also called lupus profundus, is an uncommon but well-established manifestation of both chronic cutaneous (discoid) LE and systemic LE. Although LE panniculitis characteristically may involve the face, specific parotid and periparotid involvement has not, to the best of our knowledge, been previously reported.
We describe the clinicopathologic correlation of two cases of LE panniculitis that presented as apparent primary parotid parenchymal disease; one as a neoplasm, the other as parotiditis. Failure to recognize LE panniculitis resulted in prolonged periods of inappropriate therapy and significant morbidity, including an unnecessary parotidectomy.
Lupus erythematosus panniculitis has well-established histologic criteria that should be considered in the differential diagnosis of an unexplained parotid mass.

Twenty-five antinuclear antibody (ANA) negative patients with systemic lupus erythematosus (SLE) or lupus-like disease were compared to 91 ANA positive patients with SLE for clinical and biological symptoms.
Cutaneous symptoms were infrequent in ANA negative patients (p less than 0.03). Thrombocytopenia (p less than 0.001), venous or arterial thrombosis (p less than 0.02) as well as cerebral infarction (p less than 0.001) were more frequent.
Three types of antiphospholipid antibodies were determined by different methods; the VDRL, the lupus anticoagulant and an ELISA for IgG anticardiolipin antibody (aCL). The frequency of a positive VDRL test was significantly higher in the ANA negative group (p less than 0.05). Correlation studies suggest that the 3 methods are not redundant and detect overlapping but not identical antibodies.
Of the 3 antiphospholipid antibody assays, only the IgG aCL test was significantly associated with thrombosis in the ANA negative group (p less than 0.02).

We investigated 33 patients affected with chilblain lesions following a persisting course of more than 1 month.
We focused on the incidence of an underlying connective tissue disease, mostly lupus erythematosus (LE), and we analyzed features of idiopathic chilblains compared with those of chilblain lesions associated with connective tissue disease. We also carried out a prospective follow-up of patients.
Eleven patients included in the study were free of any clinical and/or laboratory abnormality suggestive of connective tissue disease, while 22 of 33 patients showed 1 or several abnormalities raising suspicion for connective tissue disease, and among them 8 had a diagnosis of systemic lupus erythematosus (SLE) established at initial evaluation based on the American College of Rheumatology revised criteria. The comparative analysis of patients with idiopathic chilblains and patients with chilblains associated with LE showed that female sex and persistence of lesions beyond cold seasons were significantly associated with chilblain LE.
Histopathologic studies of chilblain lesions did not reveal features typical of LE in any case, but revealed a higher incidence of a deep perisudoral infiltrate in idiopathic chilblains. In patients showing signs of connective tissue disease, positive cutaneous immunofluorescence was correlated with the presence of circulating antinuclear antibodies. Two patients had an ascertained diagnosis of SLE with severe manifestations during prospective follow-up, requiring treatment with oral steroids in both cases.
Chilblains following a chronic course may reveal connective tissue disease, and patients affected with chilblains associated with autoimmune abnormalities may develop severe SLE. Accordingly, long-term follow-up of these patients is warranted.

We report a case of systemic lupus erythematosus associated with C1q deficiency. Our patient presented at the age of 6 years with cutaneous lupus. She later developed Raynaud's phenomenon, non-scarring alopecia, oral ulceration and grand mal seizures due to cerebral vasculitis.
Complement C3 and C4 levels were consistently normal during flares of her lupus and haemolytic activity of her complement was absent, suggesting a deficiency of an early component of the complement cascade. No C1q could be detected.

BACKGROUND: The gene deletion responsible for the type I human complement C2 deficiency was reported in 1992. The purpose of our study is to evaluate clinical and immunological characteristics of 11 patients with lupus erythematosus and type I C2 deficiency.
OBSERVATIONS: We observed 5 patients with a homozygous C2 deficiency and 6 with a heterozygous C2 deficiency. Eight patients had systemic lupus erythematosus, 2 had subacute cutaneous lupus erythematosus, and 1 had chronic lupus erythematosus. Photosensitivity was present in 73% of the patients, and 64% tested positive for anti-Ro (SSA) antibodies. Renal involvement that required immunosuppressive therapy was present in 54% of the patients. Ninety percent of the patients tested positive for antinuclear antibodies, and 54% tested positive for anti-double-stranded DNA antibodies. Phenotyping of the fourth component of the complement was performed in 82% of the patients and showed a C4A4B2 phenotype, which is suggestive for the type I C2 deficiency.
CONCLUSIONS: Most patients with lupus erythematosus associated with C2 type I deficiency are photosensitive, and this is probably related to the presence of anti-Ro (SSA) autoantibodies. The prognosis for those patients is not better than that for patients with lupus erythematosus in general.

PURPOSE: To describe the ophthalmic findings of patients with discoid lupus erythematosus.
METHOD: We describe two women who originally were thought to have asymmetric posterior blepharitis; however, the involved eyelid also had an erythematous, scaly cutaneous lesion.
RESULT: In both patients, histology and immunofluorescence studies performed on cutaneous biopsy specimens established the diagnosis of discoid lupus erythematosus.
CONCLUSIONS: It is important to diagnose discoid lupus of the eyelids because misdiagnosis can delay treatment and thus lead to deformities of the eyelid margin. Misdiagnosis can also lead to a complicated full-thickness eyelid biopsy and delay the diagnosis of systemic lupus erythematosus.

Department of Pathology, University of North Carolina Hospitals, Chapel Hill, North Carolina, USA.
BACKGROUND: The clinical distribution and character of cutaneous lupus erythematosus lesions can simulate squamous neoplasms, leading physicians to submit a shave biopsy specimen with a differential diagnosis of squamous neoplasm.
OBJECTIVE: Our aim was to describe histologic features of interface dermatitis that cause difficulty in distinguishing between cutaneous lupus erythematosus and squamous neoplasia in shave biopsy specimens and to identify distinguishing criteria.
METHODS: Twenty-six biopsy specimens from 10 patients initially diagnosed with squamous neoplasia that ultimately proved to be cutaneous lupus erythematosus were identified. Comparisons were made of these to 38 control biopsies of chronic cutaneous lupus erythematosus and 34 control biopsies of keratoses/carcinomas without lupus. All biopsies were scored (0 or 1: absent or present) with respect to 11 histologic criteria.
RESULTS: The criteria of perifollicular inflammation, follicular plugging, vacuolar interface change, compact orthokeratosis, and acrosyringeal inflammation were significantly more common in the lupus cases than in the keratoses/carcinomas controls. The mean lupus case score was 6.88, lupus control score 6.55, and keratoses/carcinomas control score 5.08.
LIMITATIONS: A limited number of patients were studied. Microscopic observations and assumptions with inherent subjectivity were used in establishing the histologic scores.
CONCLUSION: Use of the criteria presented, although not absolute, should alert one to the possibility of lupus in an atypical squamous proliferation, especially in suspected squamous neoplasms that worsen or recur after therapy.
Hypertrophic lupus erythematosus: a clinicopathological study of 14 cases.Daldon PE, De Souza EM, Cintra ML.
Department of Dermatology, and Department of Pathology, State University of Campinas - UNICAMP, Campinas/SP, Brazil.
J Cutan Pathol. 2003 Aug;30(7):443-8. Abstract quote BACKGROUND: Hypertrophic lupus erythematosus (HLE) is a distinct and rare subset of lupus erythematosus (LE). It is characterized by verrucous lesions, chronic in its course, and resistant to treatment. The purpose of this study was to identify clinical and histological characteristics of HLE.
METHODS: We review our experience with 14 cases of HLE identified in a group of 220 patients with different forms of LE, at the UNICAMP Hospital, between 1976 and 2002.
RESULTS: All patients presented verrucous plaques concomitantly with discoid lesions. The most common sites of involvement were the face and the arms. Histology of HLE lesions revealed pseudoepitheliomatous hyperplasia engulfing elastotic material. Elastic fibers were seen in migration throughout the epidermis. Classic features of LE were noted in all cases. Three of the patients developed hyperkeratotic papules with central keratinous plug on their arms at the previous LE sites. These lesions resemble clinically and histopathologically keratoacanthomas. In one patient, HLE lesion progressed to squamous cell carcinoma (SCC), 26 years after the onset of the disease.
CONCLUSIONS: Transepithelial elimination of the elastotic material may be a feature of HLE. Some HLE lesions may present as keratoacanthoma, but classical features of LE aid the correct diagnosis. SCC may arise on a long-standing HLE lesion; therefore HLE requires clinical and histopathological follow up.
Amyloid deposition is frequently observed in skin lesions of hypertrophic lupus erythematosus.Khan MA, Maruno M, Khaskhely NM, Uezato H, Nonaka S.
Department of Dermatology, Faculty of Medicine, University of the Ryukyus, Nishihara, Okinawa, Japan
J Dermatol. 2002 Oct;29(10):633-7. Abstract quote Four cases of Hypertrophic Lupus Erythematosus (HLE) were reported. The lesions of HLE were observed on the forearms, face and hands in all four cases. Clinically, the lesions were erythematous, hyperkeratotic plaques.
The clinical course was marked by chronicity and progression of the lesion. Histologically, marked hyperkeratosis, parakeratosis, acanthosis, degenerative changes of basal cells in H/E stain, and thickened, multilayered basement membrane in PAS stain, were observed. The observations of Dylon stain revealed that localized amyloid deposition was observed in all four cases of HLE lesions, as fluorescent-orange colored amyloid deposits in the papillary dermis and subepidermal areas at near orjust below the dermo-epidermal junction appeared under fluorescent microscope.
On the basis of clinical and histological observations, we suggest that chronic irritation, such as sunlight exposure over a long-duration, might have caused the characteristic abnormalities at the dermo-epidermal junction and also initiated the frequency of amyloid deposits locally secondary to the diseases.
We compared our HLE cases to other types of lupus erythematosus (LE) skin lesions, as to whether deposition of amyloid materials were frequently observed or not. Amyloid deposition was observed in one case of DLE and none of the SLE cases. Localized amyloid deposition was more frequently observed in skin lesions, secondary to HLE disease, as compared to other types of LE.Hypertrophic discoid lupus erythematosus of the conjunctiva.

PURPOSE: To report the ophthalmic manifestations of hypertrophic discoid lupus erythematosus of the conjunctiva.
METHOD: Case report and review of biopsy results.
RESULTS: A 58-year-old woman with a history of chronic blepharoconjunctivitis presented with an unusual raised conjunctival lesion. Previous biopsy slides were reviewed and interpreted as diagnostic of discoid lupus erythematosus, hypertrophic or verrucous type. Both blepharoconjunctivitis and the raised conjunctival lesion resolved with hydroxychloroquine therapy.
CONCLUSIONS: A raised conjunctival mass in the context of refractory blepharoconjunctivitis should elicit suspicion for discoid lupus erythematosus. The hypertrophic variant of this disease can affect the conjunctiva.

Arch Dermatol 2003 Jan;139(1):45-9 Abstract quote OBJECTIVE: To study the clinical and immunopathologic findings of drug-induced, Ro/SSA-positive cutaneous lupus erythematosus (CLE). DESIGN: Retrospective medical and laboratory record review.
SETTING: Immunodermatology Division of Johns Hopkins Hospital (Baltimore, Md).
PATIENTS: Of 120 patients found to have anti-Ro/SSA antibodies by hemagglutination and/or double immunodiffusion, 70 had clinical and immunopathologic confirmation of CLE. Fifteen of these 70 patients had a history of new drug exposure, defined as less than 6 months, associated with disease development.
RESULTS: The disease-associated drugs included hydrochlorothiazide (5 patients), angiotensin-converting enzyme inhibitors (3 patients), calcium channel blockers (3 patients), interferons (2 patients), and statins (2 patients). The most common presentations were photodistributed diffuse erythema and subacute CLE-type lesions without evidence of significant systemic disease. All specimens revealed interface dermatitis and fine granular IgG deposition along the basement membrane zone and throughout the epidermis. Most patients experienced improvement or resolution of clinical lesions within 8 weeks and decrease of Ro/SSA titers within 8 months after discontinuation of drug treatment.
CONCLUSIONS: Antihypertensive drugs are the most commonly associated with Ro-positive CLE. Clinical and immunopathologic features of this drug-induced variant do not seem to differ from the idiopathic disease. In most cases, the disease improves or resolves on discontinuation of the offending drug treatment. It is not known if these drugs precipitate disease in patients who have subclinical disease. Drug-induced Ro/SSA-positive CLE should be included on the differential diagnosis in patients presenting with photosensitive or subacute CLE-type eruptions.
Drug-Induced Lupus Associated With COL-3 Report of 3 Cases
Jayashri V. Ghate, etal.
Arch Dermatol. 2001;137:471-474 Abstract quote
Background
Anti-angiogenesis is an exciting new approach to anticancer therapy. COL-3, a tetracycline derivative, is a novel anti-angiogenesis agent with potent preclinical anticancer activity. During the conduct of a phase 1 clinical trial for refractory metastatic cancer at the National Institutes of Health, we observed 3 individuals who developed phototoxicity followed by clinical and laboratory features of drug-induced lupus.Observations
Three of 35 patients treated with COL-3 developed sunburnlike eruptions accompanied by fever and a positive antinuclear antibody titer within 8 to 29 days of starting treatment. Two of 3 had positive antihistone antibody levels and arthralgia. One patient had marked systemic manifestations including pulmonary infiltrates and elevated erythrocyte sedimentation rate remittent for more than 1 year after discontinuing COL-3 treatment. The other 2 patients' symptoms and rash abated within 2 weeks of discontinuing therapy although the serologic markers remained abnormal for the duration of follow-up.
Conclusions
COL-3 is the second tetracycline derivative to be implicated in the development of drug-induced lupus. A sunburnlike eruption immediately preceded or accompanied the systemic and serologic changes in these 3 patients. The rapid onset and the phototoxic appearance of the accompanying eruptions might suggest that damage to the keratinocytes caused the formation of neoantigens to which autoantibodies formed.Drug-induced cutaneous lupus erythematosus, a distinct syndrome that is frequently unrecognized
Jeffrey P. Callen, MD
Louisville, Kentucky
J Am Acad Dermatol 2001;45:315-316 Article Quote of First Paragraph
Avariety of drugs have been linked to syndromes that resemble lupus erythematosus (LE). Until recently it befuddled me why dermatologists needed to know about drug-induced LE (DIL), a disease that rarely has cutaneous manifestations. DIL resembles systemic LE (SLE) but has several distinctive features. One of these is the presence of antihistone antibody, an antibody that is fairly specific for DIL. However, with the recent linkage of minocycline as a cause of DIL, it is now important that dermatologists recognize this syndrome. DIL differs from drug-induced subacute cutaneous LE (DI-SCLE), a syndrome that I believe is under-recognized.
Drug-induced systemic lupus erythematosus associated with etanercept therapy.Shakoor N, Michalska M, Harris CA, Block JA.
Lancet 2002 Feb 16;359(9306):579-80 Abstract quote Specific antagonists of tumour necrosis factor (TNF)-alpha have rapidly gained popularity for the treatment of rheumatoid arthritis. The monoclonal antibody against TNF-alpha, infliximab, has been associated with induction of systemic lupus erythematosus (SLE); however, there have been no published reports of drug-induced SLE associated with the soluble TNF-alpha receptor etanercept.
We describe four female patients who developed signs and symptoms of SLE during treatment with etanercept; in two SLE was unambiguous. On diagnosis of SLE, etanercept was discontinued and the SLE-related symptoms promptly resolved. Etanercept should be considered in the list of agents associated with drug-induced SLE.

Am J Dermatopathol. 2010 Feb;32(1):24-30. Abstract quote
Lupus erythematosus panniculitis (LEP) is an inflammatory disorder of the subcutaneous fat in patients with lupus erythematosus (LE). It is a rare variant of the disease, which occurs approximately in 1%-3% of patients with cutaneous LE.
The purpose of this study was to investigate the clinical, histopathologic, immunophenotypical, and molecular profiles of LEP. We performed a retrospective study of 19 biopsy specimens from 17 patients with LEP. We reviewed their clinical data and reexamined the histopathology. Immunophenotyping and molecular studies were done using sections from paraffin-embedded formalin-fixed tissue. The most common clinical manifestation was a depressed patch on upper arm. Patients showed good response to variable treatment modalities, but, generally, relapse of panniculitis was noted when treatment was discontinued.
Histopathologically, most specimens revealed lymphoplasmacytic lobular panniculitis with epidermal and dermal changes of LE, hyaline fat necrosis, and lymphoid follicles. Immunohistochemistry showed a mixture of T and B cells in dermis and subcutis with a slight preponderance of T cell. Although the polymerase chain reaction analysis of the T-cell receptor-gamma gene rearrangement showed a polyclonal smear in 89.5% of cases, a small portion of specimens demonstrated monoclonality.
LEP is a chronic recurrent disease with characteristic features. Its diagnosis is often challenging, and a precise diagnosis is achievable only upon elaborate clinicopathologic correlation and integrated interpretation of all diagnostic criteria.

Background: The diagnosis of lupus erythematosus panniculitis (LEP) may be very difficult in cases in which involvement of the subcutaneous fat is the only manifestation of the disease. The main differential diagnosis is subcutaneous panniculitis-like T-cell lymphoma (SPTCL).
Methods: We performed a retrospective study reviewing the histopathologic features of 11 biopsy specimens from nine patients with LEP (M : F = 2 : 7; median age: 48 years; range: 20-71 years).
Results: Histopathologically, all biopsies revealed a lobular panniculitis, with concomitant septal involvement in 82% of them. Dermal changes included the presence of superficial and deep infiltrates (82%) and mucin deposition (73%). The majority of cases (73%) presented also some form of epidermal involvement. The subcutaneous infiltrate was composed of lymphocytes in all cases, admixed with plasma cells in 91% of cases. Lymphoid follicles with reactive germinal centers were detected in 45% of cases. Immunohistochemistry showed a predominance of alpha/beta-T-helper and cytotoxic lymphocytes in 80% of cases admixed with B lymphocytes. The polymerase chain reaction analysis of the T-cell receptor (TCR)-gamma gene showed a polyclonal smear in all cases.
Conclusions: Our study shows that the most useful histopathologic criteria for distinguishing LEP from SPTCL are the presence of involvement of the epidermis, lymphoid follicles with reactive germinal centers, mixed cell infiltrate with prominent plasma cells, clusters of B lymphocytes, and polyclonal TCR-gamma gene rearrangement.J Am Acad Dermatol 1981;5:673

An immunohistochemical study on a case of lupus erythematosus panniculitis (LEP), without discoid lupus erythematosus (DLE) or systemic lupus erythematosus (SLE) signs, showed that the cells in skin infiltrates were immunologically committed lymphocytes (OKT4, OKT8, OKT11 and HLA-DR positive cells) and elements of the monocyte-macrophage lineage (Leu M3 and Leu M5 positive).
No immunophenotypically identifiable B-lymphocytes were seen. Immunofluorescent IgG, IgM, C3 and C4 deposits were found in blood vessel walls of the deep dermis.
These findings, similar to that described in the skin changes of SLE and DLE, suggest that immunological mechanisms are operative in localized LEP, where the dermal lesions are the only expression of the disease.

Lupus erythematosus profundus (LEP) is an unusual variant of cutaneous lupus erythematosus (CLE)that is characterized by chronic, recurrent inflammation of the subcutaneous tissue leading to fibrosis. It is found in the settings of both discoid and systemic lupus erythematosus. Generalized forms are extremely rare.

Neonatal lupus erythematosus (NLE) is an inflammatory disorder of neonates characterized by transient cutaneous lesions and/or congenital heart block.
The cutaneous lesions usually heal with minimal scarring, but healing may be delayed for many months in occasional cases. Photosensitivity is recognized as a component of this syndrome. A large proportion of this maternal population is asymptomatic, although the mothers' potential risk for developing CTD in the future remains to be determined. Moreover, this maternal group may exhibit a tendency to fetal wastage. La(SSB) and/or Ro(SSA) antibody is almost universally present in the sera of the neonatal lupus mothers and their infants.
Since these antibodies may have a pathogenetic role in NLE, screening of infants with isolated CHB and/or cutaneous lesions suggestive of LE, and their mothers, for the presence of Ro(SSA) and La(SSB) antibodies is strongly recommended. HLA studies reveal that infants of Ro-positive mothers bearing the HLA, A1, B8, DR3, MB2 and MT2 phenotypes are at increased risk of developing neonatal lupus, in sharp contrast to infants of Ro-positive mothers bearing the DR2 and/or MB1/MT1 phenotypes.
Recognition of the protean manifestations of this complex disorder by obstetricians, pediatricians, cardiologists, and dermatologists will undoubtedly lead to increased detection of NLE and afford further opportunity to elucidate more fully the etiology of this syndrome.

J Cutan Pathol 1991 Oct;18(5):333-8 Abstract quote
Three cases of neonatal lupus erythematosus (NLE) syndrome are described.
The key diagnostic sign is the erythematous and annular clinical appearance of lesions. The histopathologic findings may be subtle in NLE syndrome compared with discoid or subacute cutaneous lupus erythematosus. Direct immunofluorescence testing may be useful in supplementing the histopathologic evaluation. Detection of immunoglobulins, complement, or both at the basement membrane zone in lesional skin by immunofluorescence occurs in approximately half of cases; a negative study does not preclude the diagnosis of NLE syndrome.
Clinical and serologic evaluation of both the infant and the mother are important in establishing a diagnosis of NLE syndrome, particularly when histopathologic findings are subtle.

Neonatal lupus erythematosus (NLE) is an autoimmune disease whose major findings are subacute cutaneous lupus erythematosus (SCLE) skin lesions and congenital heart block.
Babies have maternal anti-Ro/SSA, anti-La/SSB, or anti-U1RNP autoantibodies. Anti-Ro/SSA are the predominant autoantibodies, having been found in about 95% of cases. The autoantibodies pass through the placenta from mother to child. Skin disease resolves at about the time that maternal autoantibodies can no longer be detected in the baby. NLE therefore provides the strongest clinical evidence that autoantibodies are involved in at least some manifestations of lupus erythematosus, but there is as yet no definitive evidence implicating autoantibodies in the disease process.
Skin disease usually begins after birth, is transient, and does not result in scarring. Cardiac disease begins in utero, and the heart block is almost always permanent. Many babies require pacemakers, and about 10% die from complications related to cardiac disease. In some cases, transient liver disease or thrombocytopenia have been observed. Individuals who had NLE usually have healthy childhoods but may develop autoimmune disease in adulthood. Whether the later development of autoimmune disease is a common or an unusual event is not yet known. Mothers of babies with NLE may be asymptomatic initially, but with time usually develop symptoms of autoimmune disease.
The most typical constellation of symptoms in our group of approximately 30 mothers of babies with NLE is that of Sjogren's syndrome. Most babies exposed to anti-Ro/SSA autoantibodies during gestation will not develop NLE. There is no test to determine prospectively which babies will be affected.
Treatment during gestation is still controversial and, if attempted, should be reserved for fetuses with potentially life-threatening disease. Treatment after birth consists of topical management for skin disease and pacemaker implantation, if necessary, for heart block. Systemic steroids may be given for serious internal disease.

We present a case of neonatal lupus erythematosus (NLE) in a black infant presenting with symmetrical depigmented macules on the face resembling vitiligo. NLE is a rare condition affecting newborn infants of mothers who have connective tissue disease, with or without autoantibodies to extractable nuclear antigens Ro (SS-A), La (SS-B) or ribonucleoproteins. Infants present with cutaneous lesions or congenital heart block or both.
The skin lesions are usually annular and erythematous and transient and resemble those of subacute cutaneous lupus erythematosus. The presentation of this patient was therefore striking.

Neonatal lupus erythematosus (NLE) is an uncommon disease that is manifested by cutaneous lesions, cardiac conduction defects, or both, that appear in utero or shortly after birth. In approximately 95% of patients, anti-Ro antibody (Ro[SS-A]) has been identified and has become the serologic marker for NLE. Since 1987 there have been four reported cases of Ro- and anti-La antibody (La[SS-B])-negative, U1RNP antibody-positive, NLE.
Our affected twin, as well as all other infants with U1RNP-positive NLE, had cutaneous lesions similar to those in Ro-positive NLE, although they lacked systemic abnormalities, including cardiac conduction defects. HLA typing of mothers with infants with U1RNP-positive NLE revealed the presence of HLA-DR4, DQw1, or DQw3 phenotypes. Our typing confirms these findings. As with Ro-positive NLE, no distinct HLA associations were demonstrated in the infants. Unlike Ro-positive mothers, all mothers with a U1RNP-positive infant with NLE had connective tissue disease at the time of the diagnosis and had a different spectrum of disease.
We describe the clinical, serologic, and immunogenetic findings in the first reported case of U1RNP-positive NLE in dizygotic twins in whom the NLE disease expression was discordant.

BACKGROUND: Persistent telangiectases are a feature of neonatal lupus erythematosus (NLE) but have generally been noted in areas of prior inflammatory disease. The occurrence of vascular macules and papules at sites without preceding dermatitis has not been reported in NLE.
OBJECTIVE: Our purpose was to emphasize a previously unidentified aspect of cutaneous NLE: the presence of angiomatous or matlike telangiectases in sites without antecedent or concurrent dermatitis.
METHODS: We describe seven patients in which telangiectatic macules or angiomatous papules were primary or early features of NLE.
RESULTS: Five infants lacked a history of preceding or concurrent inflammatory lesions at sites of telangiectasia development. In four infants findings included vulvar or inguinal angiomatous papules.
CONCLUSION: Telangiectases may be a presenting feature of NLE, can be found in sun-protected sites, and may occur independent of "lupus dermatitis

Neonatal lupus erythematosus (NLE) is a rare disorder believed to be caused by the transplacental passage of specific autoantibodies from the mother to the fetus. Affected infants typically present with either characteristic skin lesions developing in the first month or later in life or congenital heart block.
We report a very unusual case of NLE that was characterized by congenital skin atrophy, erosions, alopecia, and profound pancytopenia. Ro, La, and RNP antibodies were absent, and the diagnosis was made because of light microscopic and immunofluorescent findings.
This case emphasizes that NLE can have widespread congenital skin involvement and suggests that at least some cases are mediated by antibodies other than Ro, La, and RNP.

PURPOSE: Neonatal lupus erythematosus is caused by the transplacental passage of maternal autoantibodies. The aim of this study was to determine the risk of connective tissue disorders in mothers of children with cutaneous neonatal lupus erythematosus, as compared with the risk in mothers of children with congenital heart block, which is also often caused by maternal autoantibodies.
SUBJECTS AND METHODS: We prospectively studied all mothers of children with cutaneous neonatal lupus erythematosus during a 14-year period at the Hospital for Sick Children, Toronto, Ontario, Canada. We identified 28 mothers, of whom 24 were eligible for study. The health and antibody status of the mothers were determined at the birth of the child and at followup.
RESULTS: All mothers had anti-Ro antibodies at the time of birth. Initially 10 mothers were healthy and 14 mothers had either a defined (n = 9) or an undifferentiated (n = 5) autoimmune disorder. At a mean follow-up of 7 years, 13 (1 of whom had died) had a defined connective tissue disease, and 5 had an undifferentiated autoimmune disorder. Only 6 (25%) remained asymptomatic. By comparison, 36 (56%) of 64 mothers of children with congenital heart block were asymptomatic at follow-up (P <0.005).
CONCLUSIONS: The majority of mothers of children with cutaneous neonatal lupus erythematosus had a defined or undifferentiated autoimmune disorder at the time of the child's birth, and others developed these conditions during follow-up. The health of these mothers appears to differ from that of mothers of children with congenital heart block.

Rowell's syndrome is the name given to a distinct group of patients with lupus erythematosus who develop erythema multiforme-like lesions and have a characteristic serological picture.
We report a case of a 29-year-old woman of Afro-Caribbean origin who presented with an erythema multiforme-like eruption on the hands. Subsequently she developed painful erythematous swellings on the feet and scaly plaques on the forearm and thigh consistent with subacute cutaneous lupus. She developed a positive antinuclear factor and had positive anti-Ro and anti-La antibodies and a positive rheumatoid factor.
All of these features are consistent with Rowell's syndrome which we believe is a rare but distinct variant of cutaneous lupus erythematosus.

J Am Acad Dermatol 2001;44:925-31 Abstract quote
Background: Recently, the induction of subacute cutaneous lupus erythematosus (SCLE) and exacerbation of systemic lupus erythematosus by terbinafine have been reported.
Objective: We describe 4 cases of SCLE, one associated with chilblain lupus, which occurred during therapy with oral terbinafine for onychomycosis.
Methods: Of 21 consecutive patients with SCLE attending the outpatient dermatology department at Muenster University clinic during a 1-year period, 4 patients with terbinafine-induced SCLE were seen. Patients were examined fully and photographed; histologic findings as well as serologic and follow-up data were evaluated.
Results: In addition to high titers of antinuclear antibodies (ANA) with a homogeneous pattern, anti-Ro(SS-A) antibodies were present; in 3 of 4 women, anti-La(SS-B) antibodies were also found. All patients had anti-histone antibodies as in drug-induced lupus and showed the characteristic genetic association of SCLE with the HLA-B8,DR3 haplotype; moreover, in 2 cases, HLA-DR2 was also present. After discontinuation of terbinafine, ANA titers decreased; anti-histone antibodies also became undetectable within 4˝ months in 3 patients concomitant with subsidence of the SCLE eruption in all patients.
Conclusion: Terbinafine is a drug that appears to infrequently induce SCLE with high titers of ANAs and anti-histone antibodies in genetically susceptible persons.

Background
Subacute cutaneous lupus erythematosus is a nonscarring, non–atrophy-producing photosensitive cutaneous disorder. Half of the patients have 4 or more of the criteria for classification as systemic lupus erythematosus. In some patients, drugs induce or exacerbate the cutaneous disease.Observation
We describe 5 patients who had either an exacerbation or a new onset of subacute cutaneous lupus erythematosus while taking terbinafine for presumed onychomycosis.Conclusion
In general, terbinafine is a safe drug, but perhaps patients with known lupus erythematosus or photosensitivity are predisposed to drug-induced or drug-exacerbated disease.

Arch Dermatol 2002 Sep;138(9):1175-8 Abstract quote OBJECTIVE: To compare the frequency and severity of systemic disease in patients with subacute cutaneous lupus erythematosus (SCLE) followed up in a dermatology practice vs patients with systemic lupus erythematosus (SLE) followed up in a rheumatology practice.
DESIGN: Case-control comparison of patients matched for age, sex, and ethnicity.
SETTING: University-affiliated dermatology and rheumatology practices.
PATIENTS: Seventy-six patients with SCLE were compared with 24 patients with SLE.
INTERVENTION: All medical records were reviewed and the patients were interviewed.
MAIN OUTCOME MEASURES: Systemic and serologic findings were compared between patients with SCLE and those with SLE.
RESULTS: Hematologic disorders were present in 6 patients (8%) with SCLE and in 13 patients (54%) with SLE (P<.001). Serositis was present in 1 patient (1%) with SCLE and in 3 patients (12%) with SLE (P =.04). Renal involvement was present in 12 patients (16%) with SCLE and in 6 patients (25%) with SLE (P =.36). Antinuclear antibodies were found in 52 patients (68%) with SCLE compared with 23 patients (96%) with SLE (P =.006). Anti-Ro antibodies were found in 37 patients (49%) with SCLE compared with 10 patients (42%) with SLE (P =.64). Other serologic abnormalities (anti-native DNA, anti-Sm antibody, or anti-U(1)RNP) were present in 6 patients (8%) with SCLE compared with 15 patients (62%) with SLE (P<.001). Photosensitivity was present in 65 patients (86%) with SCLE, compared with 11 patients (46%) with SLE (P<.001).
CONCLUSIONS: This analysis reveals a dissimilar frequency of internal organ involvement between patients with SCLE and SLE. Renal disease was similar in frequency and severity, and documented central nervous system involvement was rare in both groups.

Departments of Dermatology at Heinrich-Heine-University of Dusseldorf and University of Witten-Herdecke.
J Am Acad Dermatol. 2003 Jun;48(6):901-8. Abstract quote BACKGROUND: In a recent study, we demonstrated that lupus erythematosus (LE) tumidus (LET) is a distinct subset of cutaneous LE (CLE), which is clinically characterized by erythematous, urticaria-like, nonscarring plaques in sun-exposed areas.
OBJECTIVE: Our purpose was to analyze skin biopsy specimens from 80 patients with this disease and to determine whether it could be differentiated from other variants of CLE on histopathologic grounds.
METHODS: Skin biopsy specimens from 53 primary and 38 UVA- and/or UVB-induced lesions of 80 patients with LET were examined and compared with skin biopsy specimens from patients with discoid LE (DLE) and subacute CLE (SCLE).
RESULTS: Specimens from LET lesions showed a characteristic and diagnostic pattern of perivascular and periadnexal cellular infiltrates in the papillary and reticular dermis composed almost entirely of lymphocytes. In some cases, few scattered neutrophils were present. Furthermore, interstitial mucin deposition was observed in all specimens, as confirmed by colloidal iron staining. In contrast to discoid LE and subacute CLE lesions, epidermal atrophy or alteration at the dermoepidermal junction was not detected.
CONCLUSION: Skin lesions of patients with LET present with specific histopathologic features, and the differences compared with subacute CLE and discoid LE further support the concept to consider LET as a separate entity of CLE.

Arch Dermatol 2000 Aug;136(8):1033-41 Abstract quote
BACKGROUND: Lupus erythematosus tumidus (LET) is characterized clinically by erythematous, succulent, edematous, nonscarring plaques in sun-exposed areas. Results of histological examination show perivascular and periadnexal lymphocytic infiltration and interstitial mucin deposition. The main differential diagnoses are polymorphous light eruption, Jessner's lymphocytic infiltration of the skin, reticular erythematous mucinosis, and pseudolymphoma. Since its first description in 1930, LET has been documented rarely in the literature, and its clinical importance has not been fully appreciated.
OBSERVATIONS: We characterized 40 patients with clinical and histological features of LET observed at our department from 1984 through 1998. The onset of the disease clustered in summer because of sun exposure, and 28 (70%) of the patients showed a remarkable photosensitivity confirmed by results of provocative phototesting. A complete resolution of the skin lesions was seen after systemic therapy with antimalarials and, in some cases, with local corticosteroids or spontaneously without any treatment. In 4 (10%) of the patients, antinuclear antibodies were detected; however, there was no evidence of underlying systemic involvement in any of the patients.
CONCLUSIONS: Our data constitute the largest number of patients with LET collected until now. The clinical picture, extreme photosensitivity, histological findings, and effective treatment with antimalarials are so characteristic that LET should be considered as a separate entity and differentiated from other variants of cutaneous LE.

Photosensitivity is an important characteristic feature of several forms of lupus erythematosus (LE), and induction of skin lesions by UV-A and UV-B irradiation has been proved to be an optimal model for evaluating light sensitivity in patients with this disease. Because lupus erythematosus tumidus (LET) has rarely been documented in the literature and is often difficult to differentiate from other photodermatoses such as polymorphous light eruption, we performed photoprovocation tests in 60 patients with LET according to a standardized protocol.
Areas of uninvolved skin on the upper back were irradiated with single doses of UV-A (100 J/cm2) and/or UV-B (1.5 minimal erythema dose) daily for three consecutive days. Interestingly, patients with LET are more photosensitive than those with subacute cutaneous lupus erythematosus, and in our study experimental phototesting revealed characteristic skin lesions in 43 patients (72%). Because of the latency period in developing positive phototest reactions, it might be difficult for these patients to link sun exposure with their skin lesions. Furthermore, our data revealed a positive correlation of antinuclear antibodies and positive provocative phototest reactions in these patients as seen for other forms of LE.
In conclusion, the high incidence of positive phototest reactions in correlation with the clinical findings, history of photosensitivity and antinuclear antibodies enable the classification of LET as the most photosensitive type of LE.

EXTRACUTANEOUS ORGANS See file KIDNEY
World Health Organization (WHO) Classification of Lupus NephritisThe kidney is involved in 60-70% of cases by routine light microscopy but in nearly all cases if examined with electron microscopy or immunofluorescence
Damage begins with deposition of DNA-anti-DNA complexes within the glomeruli basement membrane
Immunoglobulins and complement are then attracted leading to cellular damage.These deposits may occur in the mesangium, intramembranous, subepithelial, or subendothelial
Subendothelial deposits may cause thickening of the wall leading to a wire loop lesion
In about 50% of patients, the kidney tubules may also have deposits along the basement membrane.Nonlupus nephritides in patients with systemic lupus erythematosus: A comprehensive clinicopathologic study and review of the literature

Renal biopsy specimens from patients with systemic lupus erythematosus (SLE) rarely show changes that are pathogenetically and morphologically unrelated to SLE. The morphology and behavior of these nonlupus nephritides are not well known.
Two hundred fifty-two renal biopsies performed on 224 patients with SLE collected from 3,036 native kidney biopsies performed between 1975 and 1998 were reviewed, and those that showed nonlupus nephritides (index biopsies) were selected for studies.
Thirteen biopsy specimens with nonlupus nephritides were identified in 13 patients, who belonged to 3 clinically distinct groups.
Group I included 6 patients in whom SLE was diagnosed at the time of index biopsies. The index biopsies in these patients showed focal segmental glomerusclerosis (FSGS; 3 cases), Immunoglobulin (Ig) M nephropathy (1 case), and thin basement membrane disease (1 case). The diagnostic features for FSGS included segmental sclerosis involving at least 1 glomerulus, absence of lupus nephritis or other conditions that may cause nonspecific segmental sclerosis of glomeruli such as ischemia or nephrosclerosis, and nephrotic-range proteinuria. There was uniform, global, diffuse and marked thinning of the glomerular basement membrane in the case of thin basement membrane disease.
Group II included 3 patients in whom SLE was diagnosed 2 to 9 years before the time of index biopsies and SLE was active at the time of biopsy. The index biopsies in these patients showed FSGS (2 cases) and hypertensive nephrosclerosis (1 case).
Group III included 4 patients in whom SLE was diagnosed 5 to 36 years before the time of index biopsies and SLE was inactive at the time of biopsy. The index biopsies in these patients showed 1 case each of amyloidosis, FSGS, hypertensive nephrosclerosis, and allergic acute tubulointerstitial nephritis. Previous renal biopsies, performed in 5 patients, showed IgM nephropathy (1 case), diffuse proliferative lupus GN (1 case), focal proliferative lupus GN (1 case), and mesangial proliferative lupus GN (2 cases). Follow-up biopsies, performed in 3 patients, confirmed the diagnosis of FSGS (2 cases) and hypertensive nephrosclerosis (1 case) noted in the index biopsies. Nonlupus nephritides may occasionally be encountered in SLE patients, regardless of clinical or serologic disease activity.
These renal lesions display a broad morphologic spectrum in which FSGS seems most frequent. Renal biopsy plays a crucial role in identifying these lesions, which may have prognostic and therapeutic implications distinct from those of lupus nephritis.

Michael D. Hughson, etal.
Arch Pathol Lab Med 2001;125:475–483 Abstract quote
Context.—Acute alveolar hemorrhage in systemic lupus erythematosus usually occurs as a pulmonary-renal syndrome. In most cases, the lungs show “bland” alveolar hemorrhage with little or no inflammation. Whether this alveolar injury is similar to the better-defined noninflammatory renal lupus vasculopathy is unresolved.
Objectives.—To investigate the relationships and the mechanisms of small vascular injury in the lung and kidney of 2 lupus patients who died of diffuse AH. Methods.—We investigated the relationship of AH to immune complex deposition in the lungs of 6 patients with systemic lupus erythematosus and correlated the findings with glomerular and vascular disease in the kidney. Lung and kidney were studied by light, immunofluorescence, and/or electron microscopy; apoptosis was investigated using in situ nick-end labeling.
Results.—The clinical course of 2 patients was complicated by alveolar hemorrhage, and the lungs of these patients revealed alveolar wall immune complex deposits and bland alveolar hemorrhage. These 2 patients had World Health Organization class IV lupus nephritis and renal arterioles involved by a noninflammatory lupus vasculopathy. Apoptosis was identified in the lupus microangiopathy and in alveolar walls within areas of alveolar hemorrhage. Alveolar wall immune complex deposits were not found in 4 patients who had a lupus glomerulonephritis but did not have renal lupus vasculopathy. Apoptosis was not seen in renal arterioles or lungs of these 4 cases, except in areas of diffuse alveolar damage or herpesvirus pneumonia.
Conclusions.—Our findings indicate that alveolar hemorrhage in systemic lupus erythematosus, characterized by bland alveolar wall changes, is pathogenetically similar to the lupus microangiopathy of the kidney. In both lung and kidney, the pathogenesis of the microvascular injury appears to be related to immune complex deposition and the induction of apoptosis.

ADDITIONAL DIFFERENTIAL DIAGNOSIS KEY DIFFERENTIATING FEATURES INTERFERON INJECTION SITE
Department of Dermatology, University Hospital, Madrid, Spain.
Background: Interferon therapy at the injection sites has been related to different cutaneous lesions including erythema and induration as the most frequent ones. While the glycoprotein induces fatigue, fever and is even believed to precipitate autoimmune disorders such as type I diabetes, thyroid disease and systemic lupus erythematosus, a lupus erythematosus-like histologic reaction at the interferon injection site has never been reported. To our knowledge, a microscopic self-resolving lesion mimicking lupus erythematosus at the injection site of interferon has not been described.
Results: We report five cases of cutaneous lesions at the inoculation site of interferon with a histopathologic lupus erythematosus-like pattern. Three of them were receiving interferon alfa therapy because of a malignant melanoma and the other two patients were receiving interferon beta-1b for multiple sclerosis. Biopsy specimens taken from different lesions showed similar microscopic findings consisting of dermal mucin deposits and dense lymphocytic infiltrates along hair follicles with hydropic degeneration of follicular basal layer.
Conclusions: Multiple cutaneous lesions related to interferon at the injection site have been reported, but none of them with a histologic lupus-like presentation. In this study we describe five cases in which interferon therapy has induced a resolutive cutaneous lesion mimicking lupus erythematous. This peculiar microscopic pattern has been previously described once before, but interpreted as cutaneous mucinosis.LYMPHOMA Lupus profundus, indeterminate lymphocytic lobular panniculitis and subcutaneous T-cell lymphoma: a spectrum of subcuticular T-cell lymphoid dyscrasia.

INTRODUCTION: The diagnosis and classification of lymphocytic lobular panniculitis (LLP) has historically proven to be a difficult challenge. We encountered 32 cases of primary LLP which could be categorized as: 1) lupus erythematosus profundus (LEP) (19 patients); 2) an indeterminate group termed indeterminate lymphocytic lobular panniculitis (ILLP) (6 patients); and 3) subcutaneous T-cell lymphoma (SCTCL) (7 patients).
OBJECTIVE: We attempted to better define the subtypes of LLP by morphologic, phenotypic and genotypic features and to correlate those features to clinical presentation and outcome.
METHOD: Skin biopsy material was studied by conventional light microscopy, through immunophenotyping performed on sections from paraffin-embedded, formalin-fixed tissue and in some cases on sections of tissue frozen after receipt in physiological (Michel's) medium, and by polymerase chain reaction single-stranded conformational polymorphism analysis to assess for clonality of T-lymphocytes. Clinical features were correlated to histologic, phenotypic, and genotypic analyses.
RESULTS: Patients with LEP had a prior diagnosis of LE or overlying skin changes which light microscopically were characteristic of LE. Patients with ILLP had no concurrent or prior history of LE, no systemic symptoms or cytopenias, and a clinical course not suggestive of lymphoma. Cases of SCTCL showed hemophagocytic syndrome and/or lesional progression with demise attributable to the disease. Lesions in all groups showed proximal extremity predilection. Females predominated in the LEP group. The average age of onset was 38, 40 and 55 years in the LEP, ILLP and SCTCL groups, respectively. Cytopenia was seen in 4 LEP patients; 1 also developed fever. In LEP and ILLP, lesions resolved with hydroxychloroquine and/or steroid therapy, with recurrences following cessation of therapy. In the SCTCL group 4 developed hemophagocytic syndrome, 4 died within 2 years of diagnosis, and 3 went into remission following chemotherapy. The LEP and SCTCL groups manifested histological similarities: dense perieccrine and lobular lymphocytic infiltration, lymphoid atypia, histiocytes with ingested debris, eosinophilic necrosis of the fat lobule and thrombosis. The atypical lymphocytes although pleomorphic did not have a cerebriform morphology. The infiltrate in ILLP had a similar cytomorphology and distribution with variable angioinvasion which in all save one case was of lesser intensity and was not associated with significant fat necrosis or vasculitis. Germinal centers, dermal/subcuticular mucin deposition and an atrophying interface dermatitis with hyperkeratosis and follicular plugging were largely confined to the LEP group. Erythrophagocytosis, characteristic of SCTCL, usually indicated a supervening subcuticular lymphoid dyscrasia when encountered in ILLP and LEP. SCTCL showed a selective loss of CD5 expression with or without diminution in CD7 and monoclonal CD3 expression. Of 4 cases studied, 3 showed a CD8 dominant infiltrate while 2 others exhibited CD56 and CD30 positivity, respectively. All cases of SCTCL with amplifiable DNA showed T-cell clonality. Similar molecular and phenotypic features indicative of subcuticular lymphoid dyscrasia were encountered in cases of LEP and ILLP including a reduction in CD5, CD7, and/or monoclonal CD3 expression, a preponderance of CD8 lymphocytes within the subcutaneous fat and T-cell clonality. These cases showed lymphoid atypia with variable erythrophagocytosis. Cases of phenotypically abnormal and/or clonal LEP showed one or more of local destruction, lesional size progression, fever, and cytopenias, but lesions responded to hydroxychloroquine and/or prednisone therapy and death attributable to panniculitis could not be documented. Cases that were phenotypically normal and without clonality had none of the aforesaid atypical clinical features.
CONCLUSION: Lymphoid atypia, erythrophagocytosis, loss of certain pan T-cell markers, a reduced CD4/8 ratio and TCR rearrangement define subcuticular T-cell lymphoid dyscrasia, including a subset of LEP and ILLP. The subcuticular lymphoid infiltrates represent a spectrum of histologic, immunophenotypic, and molecular abnormalities which range from those which are clearly benign to those which are clearly neoplastic, and also encompasses those cases which defy precise classification into the two aforesaid poles.
NEUTROPHILIC DERMATOSIS
Department of Pathology, Brigham and Women's Hospital, Boston, MA, USA.
- Background: Rare cases of a non-bullous neutrophilic dermatosis occurring in patients with lupus erythematosus (LE) have been reported, often as the presenting manifestation of the disease.
Methods: We reviewed hematoxylin and eosin-stained slides and obtained clinical information from four additional patients, two of whom had no prior history of LE.
Results: All patients were female, aged 16-59 (mean age 37). Clinically, the skin lesions were characterized by widely distributed pruritic papules and plaques. Three patients presented with systemic symptoms, including fever, arthritis and malaise. Histopathologic examination in all cases showed a superficial perivascular and interstitial neutrophilic infiltrate with leukocytoclasis. There was no evidence of vasculitis. Mild focal vacuolar change was a subtle feature seen only in the biopsies of the two patients with a prior history of LE.
Conclusions: It is important to consider LE in the differential diagnosis of non-bullous neutrophilic dermatoses.DLE VERSUS SCLE \Subacute cutaneous lupus erythematosus and discoid lupus erythematosus. Comparative histopathologic findings.
Bangert JL, Freeman RG, Sontheimer RD, Gilliam JN.
Arch Dermatol 1984 Mar;120(3):332-7 Abstract quote
Subacute cutaneous lupus erythematosus (SCLE) is a recently described distinct subset of lupus erythematosus (LE) having characteristic clinical, serologic, and genetic findings.
This study describes the histopathologic characteristics of SCLE and determines whether it could be differentiated from discoid lupus erythematosus (DLE) on histopathologic grounds alone. Biopsy specimens from 33 patients having either SCLE or DLE, as defined by strict clinical criteria, were examined without knowledge of the clinical diagnosis. Histologic discrimination between SCLE and DLE was accomplished in 82%. The specimens from DLE lesions had substantially more hyperkeratosis, basement membrane thickening, follicular plugging, and superficial and deep inflammatory cell infiltrate, while SCLE had more epidermal atrophy.
The histopathologic differences between SCLE and DLE further support the concept that SCLE is distinct from DLE and should be considered a unique subset of LE.

BACKGROUND: The nosologic position of subacute cutaneous lupus erythematosus (SCLE) is controversial. More than four American Rheumatism Association (ARA) criteria for systemic lupus erythematosus (SLE) are found in a proportion of patients diagnosed as having SCLE; thus such cases could be classified as SLE.
OBJECTIVE: Our purpose was to determine whether ARA criteria for SLE are helpful in differentiating SCLE from SLE and whether cutaneous and visceral changes, immunologic findings, and photosensitivity provide a basis for diagnosis of SCLE.
METHODS: A cohort of 143 patients (79 with SCLE, 58 with SLE, and six with overlapping features of SCLE and SLE) was studied clinically, histologically, and immunologically as well as by phototesting. The patients were observed for up to 10 years, and the course of the disease and response to therapy were evaluated in each group.
RESULTS: SCLE differed from SLE by cutaneous changes, significantly less frequent kidney involvement, serositis and arthritis, and the rare presence of double-stranded DNA, U1RNP, and Sm antibodies characteristic of SLE. Ro(SS-A) and La(SS-B) antibodies were detected with similar frequency, and photosensitivity was not related to the presence of Ro antibody. In contrast, photoreproduction (appearance of LE lesion in irradiated area) was significantly more frequent in patients with SCLE. The course of SCLE in older patients was less severe than in younger patients, and aggressive therapy was usually not required.
CONCLUSION: Patients with SCLE (although the majority fulfill more than four ARA criteria for SLE) show significant differences from those with SLE in terms of cutaneous and visceral involvement, immunologic findings, photosensitivity, course of the disease, and the requirement for therapy. Therefore SCLE should be recognized as a separate subset. However, cases of overlapping SLE and SCLE suggest a close relation.
