Synopsis

Cryofibrinogenemia is an acquired vascular occlusive disease that results from the cold precipitation of cryofibrinogens. Cryofibrinogens are composed of a complex of fibrin, fibrinogen, fibrin split products, albumin, plasma proteins, and immunoglobulins that reversibly precipitate in the cold. These cryoproteins cause an occlusive vasculopathy of small- to medium-sized blood vessels. While many patients are asymptomatic, cryofibrinogenemia can cause significant morbidity. The clinical exam and course is similar to type I cryoglobulinemia. Cryofibrinogenemia can be idiopathic (primary) or associated with malignancy (particularly prostatic cancer, other solid organ tumors, and lymphomas), infection, collagen vascular disease, thromboembolic disease, or oral contraceptive pills. A familial autosomal dominant form has been reported. Cryofibrinogenemia may be treatable and reversible, with a relatively prompt resolution of skin lesions with immunosuppressive therapy.
