Fibrolamellar carcinoma of the liver with a mixture of ordinary hepatocellular carcinoma: a case report.
Fibrolamellar carcinoma (FLC) of the liver is a rare variant of hepatocellular carcinoma (HCC), and only 13 cases have been reported in Japan up to 1997. We described a histologically unusual case of FLC. A 52-yr-old man was admitted to our hospital for work-up of hepatic mass. Laboratory examinations revealed no abnormalities except elevated serum alpha-fetoprotein (AFP) (2098 ng/ml). A diagnosis of HCC was made by imaging findings, and left lobectomy of the liver was performed. Histologically, the tumor was composed of areas of FLC mixed with ordinary HCC and those of pure ordinary HCC. Staining for AFP was positive in the HCC component and negative in the FLC component. Some cases of such mixed tumors have been reported in Europe and the United States, but not in Japan. We regarded our case as the first of the mixed tumor in Japan.
