Cutaneous leukocytoclastic vasculitis and myelodysplastic syndrome with little or no evidence of associated autoimmune disorders-a case report and a brief review of the literature.

Cutaneous leukocytoclastic vasculitis (CLV) is a necrotizing inflammatory disease of the small vessels in the dermis. Approximately 50% of cases with CLV are primary or idiopathic and the remainder may be associated with various diseases. Less than 1% CLV occurs in association with malignancies including leukemia, lymphoma, and myelodysplastic syndrome (MDS).
