[A case of hepatocellular carcinoma with gall bladder metastasis].

A 74-year-old male was admitted to Osaka University Hospital for advanced hepatocellular carcinoma in April 2007. CT and MRI scan showed the tumor was located mainly in posterior segment and had portal vein tumor thrombus, and the wall of gall bladder was edematous and thick, but seemed not to be close to the main tumor. We performed an extended posterior segmentectomy, tumor thrombectomy and cholecystectomy. Pathological examination showed that poorly differentiated hepatocellular carcinoma cells, which were same as the main tumor, existed in lamina propria and muscle layer of gall bladder, and invaded the submucosal vessels. So we diagnosed it as gall bladder metastasis from hepatocellular carcinoma.
