Six cases with extrahepatic growing hepatocellular carcinoma are reported. These cases could be classified two types according to the condition of the attachment to the liver.<BR>1) The Pedunculated Type (three cases) -The tumor has an obvious pedicle containing connective tissues, blood vessels and bile ducts. This type may arise from the accessory lobe of the liver. All of these cases are characteristic of carcinomatous invasion or adhesion to the adjacent tissues. The arteriography of two cases shows that these tumors make parasitic branches and their feeding hepatic arteries don't dilate. In these cases, it was necessary to resect the adjacent tissues.<BR>2) The Protrusive Type (three cases) -The tumor mainly exsists in the extrahepatic lesion, but a part of that exsists in intrahptic lesion. These cases make no adhesion to the adjacent tissues and their feeding hepatic arteries dilate in diameter. The tumor must be resected with its hepatic segment.
