Cutaneous gangrene: a rare complication of coumarin therapy.
Sodium warfarin was administered to a 59-year-old woman with congestive cardiac failure and deep vein thrombosis. After 3 days of therapy the nipple and areola of the left breast became inflamed; the entire breast then became necrotic. Gangrene spread and a simple mastectomy was performed. The patient died from pulmonary embolism 1 day after operation. Histologic examination of the breast revealed thrombi in some of the arteries and veins. The etiology of this condition is obscure, and there is no known way of preventing or effectively treating the condition. Simple mastectomy or more conservative local excision recommended.
