Fulminant liver failure is an unusual complication that may be seen in patients with hepatic infiltration by non-Hodgkin's lymphomas and leukemias. In such cases, hepatomegaly, marked abnormalities of serum liver function tests, and lactic acidosis may simulate severe viral, alcoholic, or drug hepatitis. We describe the clinical presentation of severe cholestatic hepatitis with liver failure in a patient who was found to have widespread liver involvement by Hodgkin's disease at autopsy. The major histologic findings included extensive portal and periportal Hodgkin's infiltrates, associated loss of periportal liver cells, and variable damage to small bile ducts.
