Warfarin-Induced Breast Necrosis: A Case Report
Warfarin-induced Breast necrosis (WIBN) is an exceedingly rare sequel to warfarin therapy. A close relationship was confirmed between congenital deficiency of protein C and S and warfarin usage. A predilection for this complication has been reported in fatty middle-aged women who are managing by warfarin. The sudden eruption of the bullous lesion, within mean three days after starting of warfarin therapy with or without echymous or petechia is the first sign of WIBN. The maintenance of INR in the low normal range, reducing the loading doses, especially in fatty cases may be a preventive measure in reducing risk and incidence of breast necrosis in the high-risk subjects. Early diagnosis and management are important to prevent significant tissue loss. A rare case of warfarin-related necrosis of the left breast following a mitral valve replacement is reported. Current knowledge and the preventing methods and treatment of this rare complication are reviewed.
