Warfarin-induced skin necrosis. A cutaneous sign of malignancy?
Abstract:
Patchy necrosis of the skin is a rare and unpredictable complication of oral anticoagulant therapy. Of the four patients that we have seen with this disorder, three had metastatic adenocarcinoma; in two, this was an unexpected finding. The association of a malignant neoplasm with warfarin-induced skin necrosis has not been emphasized previously. Whether such necrosis represents a clue to the presence of cancer or occurs only coincidentally in patients requiring anticoagulant therapy because of adenocarcinoma-associated thrombophlebitis must await further experience. A congenital or acquired deficiency of protein C may be the primary initiating factor.
