Pedunculated hepatocellular carcinoma was first described by Roux in 1987, and Goldberg and Wallerstein presented a case with pathological description in 1934. Since then 37 cases have been reported in the world literature. A pedunculated hepatocellular carcinoma, occurred in a 69-year-old woman, was encountered. It was attached to the Glission's capsule of the right lobe of liver inferiorly, and was connected to the porta hepatis bt a mesenteric pedicle containing arteries, veins, bile ducts and nerve bundles. The tumor mass was completely encapsulated, and measured 8.5x8x6 cm and 255 gm. It was composed of hepatocellular carcinoma of a well-differentiated, acinar type. Tumor cells were positive for HBsAg, but negative for alpha-fetoprotein on peroxidase-antiperoxidase staining. The liver exhibited macronodular cirrhosis on gross examination.
