Fulminant hepatic failure as the initial manifestation of primary hepatocellular carcinoma.

A 20-year-old male, with no history of chronic liver disease, presented with fulminant hepatic failure. The cause was not established until post mortem when it was found that he had a primary hepatocellular carcinoma in a non-cirrhotic liver. To our knowledge, this is the third report of hepatocellular carcinoma presenting in this manner. Although rare, primary malignancies of the liver should be considered in the differential diagnosis of fulminant hepatic failure, especially when other more common causes are excluded.
