Hepatocellular Carcinoma Producing Carcinoembryonic Antigen and Carbohydrate Antigen 19-9

Abstract

A case of hepatocellular carcinoma producing carcinoembryonic antigen and carbohydrate antigen 19-9 is reported. The serum level of carcinoembryonic antigen was 26,800ng/ml and carbohydrate antigen 19-9, 5,500 U/ml on the final day. Immunohistochemical study revealed positive monoclonal antibodies for these two antigens within the cytoplasm of the hepatocellular carcinoma cells. © 1992, The Japanese Society of Internal Medicine.
