Obstructive jaundice caused by hepatocellular carcinoma. Report of three cases

A cholestatic syndrome secondary to extrahepatic biliary obstruction as the presenting manifestation of hepatocellular carcinoma is described in three cases. The mechanism is related to the invasion of intrahepatic bile ducts by the carcinoma. The consequent mechanical obstruction is due to either a continuous distally growing tumor cast of the biliary tree, distal migration of a necrotic tumor fragment, or hemobilia. In the cirrhotic patient with a predisposition for the development of liver cancer, the physician should be aware of the presentation with obstructive jaundice as a mechanical complication of hepatocellular carcinoma.
