Background
This disorder is also known as hypersensitivity vasculitis, allergic vasculitis, hypersensitivity vasculitis, and allergic angiitis. It is not a specific disease but rather a clinicopathologic entity affecting the small vessels of the skin. Clinically, there are erythematous macules and palpable purpura occurring on the lower legs. Advanced lesions may have hemorrhagic bullae with ulcerations and rarely annular lesions. Leukocytoclatic vasculitis is not a disease. Once the pathologist makes this diagnosis, the burden is upon the treating physician to determine an etiology.

Leukocytoclastic vasculitis (LV) is a systemic inflammatory disorder involving mostly the small vessels. It is characterised by segmental angiocentric neutrophilic inflammation, endothelial cell damage and fibrinoid necrosis. LV is related to a variety of clinical disorders including cryoglobulinemia and, very rarely, multiple myeloma (MM), among many others.
The development of LV in patients with MM has been linked to cryoglobulinemia, infections, drugs and paraneoplasia. It has been speculated that myeloma patients with a poorer prognosis and progressive disease are more prone to develop LV. Thalidomide is a rediscovered old drug with anti-angiogenic, immunomodulatory and anti-inflammatory properties. It is highly effective in the treatment of MM and other clinical disorders such as leprosy, various cancers, graft-versus-host disease and autoimmune diseases.
We report here a female patient with Durie-Salmon stage IIA MM who initially presented with cryoglobulinemia and LV. LV in this patient was primarily considered to be the result of progressive cryoglobulinemia, which was closely associated with MM. She was successfully managed with thalidomide and dexamethasone.WARFARIN

Skin reactions associated with oral coumarin-derived anticoagulants are an uncommon occurrence. Leukocytoclastic vasculitis (LV) is primarily a cutaneous small vessel vasculitis, though systemic involvement may be encountered.
We report 4 patients with late-onset LV probably due to warfarin. All 4 patients presented with skin eruptions that developed after receiving warfarin for several years. The results of skin lesion biopsies were available in 3 patients, confirming LV Cutaneous lesions resolved in all patients after warfarin was discontinued.
In 2 of the 4 patients, rechallenge with warfarin led to recurrence of the lesions. LV may be a late-onset adverse reaction associated with warfarin therapy.
