Leukocytoclastic vasculitis is a small vessel inflammatory disease, mediated mostly by deposition of immune complexes. Medications cause 10-24% of cases of leukocytoclastic vasculitic skin lesions, but warfarin has rarely been implicated. We report a case of warfarin-induced leukocytoclastic vasculitis in a 72-year-old woman which developed 45 days after warfarin medication. Palpable purpura, hemorrhagic vesicles, and ulcers developed on both lower legs. A skin biopsy showed characteristic features of leukocytoclastic vasculitis. Warfarin was replaced by Clopidogrel, and the skin lesions gradually disappeared after 3 weeks.
