A 67-year-old man with hepatitis C virus infection and a liver tumor.

A 67-year-old man with no known liver disease was found to have an incidental tumor in the right liver lobe. His serum liver enzyme and alphafetoprotein were within normal limits, but he was found to be reactive for anti-HCV. The tumor was an intrahepatic cholangiocarcinoma. Since the only risk factor in this patient was hepatitis C infection, this case appears to support the recently suggested role of hepatitis C virus in the development of intrahepatic cholangiocarcinoma.
