Fibrolamellar carcinoma of the liver: a tumor of adolescents and young adults with distinctive clinico-pathologic features.

Abstract

Clinical and pathologic features of 23 patients with a distinctive histologic and clinical variant of hepatocellular carcinoma are summarized. The variant pattern of hepatocellular carcinoma is most common in the age group 5--35 years and occurs equally in either sex. The distinctive histologic features include 1) deeply eosinophilic neoplastic hepatocytes, many of which contain intracytoplasmic hyaline globules and distinct pale bodies and 2) fibrosis arranged in a lamellar fashion around the neoplastic hepatocytes. The histologic and gross features of the tumor have been confused both with focal nodular hyperplasia and with hepatocellular adenoma. The average survival of 32 months and the high operability rate of 48% far exceed the survival or operability for ordinary hepatocellular carcinoma. Thus, this tumor type must be recognized and considered separately when evaluating therapeutic results in large series of patients with hepatocellular carcinoma.
