Warfarin-Induced Skin Necrosis Occurring Four Days after Discontinuation of Warfarin

Abstract

Warfarin-induced skin necrosis is a rare complication of warfarin therapy. It appears between days 1 and 10 of therapy while the patient is receiving warfarin. Warfarin-induced skin necrosis occurring several days after cessation of therapy has not been reported. We report an atypical case of warfarin-induced skin necrosis which occurred 96 h after the last dose of warfarin was given while the prothrombin time was still elevated.
