Giant multinucleated hepatocytes in an adult with chronic active hepatitis

A case of an adult with chronic active hepatitis associated with giant multinucleated liver cells is presented. The giant liver cells in this case are widespread and the picture resembles neonatal hepatitis. The morphology, pathogenesis, and epidemiology of giant hepatocytes found in human neonates and adults and in experimental animals is discussed. Because the proliferative phase of giant hepatic cells is transient, this reaction may be more common than generally believed.
