title: Chronic ulcerative colitis, skin necrosis, and cryofibrinogenemia.
abstract: Necrotizing skin lesions developed in a man with chronic ulcerative colitis. No evidence of intrinsic disease of medium or small-sized vessels was found. A circulating cryofibrinogen was thought to be responsible for in situ thrombosis leading to skin infarctions. Sodium warfarin in a daily dose of 2.5 to 5 mg appears to have thwarted progression of developing lesions and the occurrence of new ones.
