Abstract: | Warfarin-induced skin necrosis is a rare complication of therapy with warfarin or other coumarin derivatives. When it occurs it usually appears 3 to 6 days after initiation of therapy and almost always between days 1 and 10. We report a case of late-onset (16 days after initiation of therapy) warfarin-induced skin necrosis and review the literature on this rarely reported variant of warfarin-induced skin necrosis. The skin lesion in our patient was not associated with either deficiency of protein C or resistance to activated protein C. Am. J. Hematol. 57:233–237, 1998. © 1998 Wiley-Liss, Inc. |
