Pedunculated hepatocellular carcinoma. Is it an entity?

Two cases of pedunculated hepatocellular carcinoma are reported. One of these was known to have been present for 5 years. Both patients are alive 1 and 2 years after surgery though the former has developed a solitary bone metastasis. The literature on 30 previously published cases is reviewed and it is concluded that, minor differences apart, this tumour is not substantially different from hepatocellular carcinomas in general. The slow growth and good prognosis relate to its extrahepatic location which may be explained by an origin from accessory lobes of the liver.
