Abstract
-
Cryoglobulinemia refers to the presence in the serum of one or more immunoglobulins that precipitate at temperatures below 37degrees C and that redissolve on rewarming. Type I cryoglobulin contains an isolated monoclonal immunoglobulin. The symptoms of type I cryoglobulinemia included purpura, Raynaud's phenomenon, distal ulcerations and gangrenous change caused by vascular occlusion resulting from protein precipitation. We report a case of type I cryoglobulinemia in a 72-year-old woman who had purpuras and gangrenes on her right elbow and left knee without distal skin lesions.
