Abstract
A 65-year-old man treated for hypertension was found to have a high serum level of AFP, and after several examinations he was diagnosed as having double cancers (IIc type gastric cancer in the antrum and hepatocellar carcinoma in the left lobe of the liver). On laparotomy, the left lobe of the liver showed natrophy but no tumor was detected in the liver. Theligamentum teres hepatis was enlarged and palpable as a hard mass which was 5 cm across indiameter. Left lobectomy of the liver including removal of the tumor of the ligamentum teres hepatis and distal gastrectomy were performed. Histopathological findings showed that the tumor had no connection with the liver itself and it was revealed to be hepatocelluar carcinoma originating from ectopic liver tissue exists in various organs such as gall bladder, suspensory ligaments of the liver, retroperitoneum, paccreas, spleen, omentum and intrathoracic space. However ectopic hepatocellar carcinoma is very rare; only four cases havebeen reported in Japan.
