A patient with purpura, acral blisters, and ulcerations was evaluated and found to have cryofibrinogenemia and an IgG K light chain monoclonal gammopathy. No other systemic illness was found. The overall incidence of significant cryofibrinogenemia in hospitalized patients is 3%. Four categories of secondary cryofibrinogenemia include neoplastic, thrombotic, infectious, and miscellaneous disorders. The patient described was not easily classified. This case is probably best considered primary or idiopathic cryofibrinogenemia.
