Cryofibrinogen is a plasma protein complex whose presence in the peripheral blood is generally asymptomatic, but may sometimes cause multiple thromboembolism in the skin, lung and myocardium. The pathological manifestations associated with cryofibrinogenaemia have been treated with plasmapheresis and fibrinolytic drugs such as streptokinase, streptodornase and/or urokinase. Good results have recently been reported with stanozolol. This prompted us to treat a patient suffering from cryofibrinogenaemia with this androgenic hormone. The patient was a 66-year-old woman with rapidly evolving leg ulcers. Stanozolol was orally administered at 4 mg b.i.d. for 5 months and then gradually reduced. Plasma cryofibrinogen disappeared after 45 d from the start of therapy and cutaneous ulcers healed in 5 months.
