Cryofibrinogens are rarely occurring cold-recepitable proteins most often associated with neoplastic diseases such as pulmonary, gastric or colonic cancers, metastatic carcinoma of the prostate, multiple myeloma and certain inflammatory diseases such as acute rheumatic fever and ulcerative colitis. Occasional cryofibrinogens are of unknown significance.
