A case of cholangiocellular carcinoma with tumor growth in the hepatic hilar bile duct is reported. A 72-year-old man was admitted with the complaint of obstructive jaundice. Abdominal computed tomography showed a low-density mass in the left lobe as well as within the hepatic hilar bile duct. A cholangiogram revealed a round filling defect at the hepatic hilus. A celiac arteriogram showed a hypervascular lesion fed by the middle hepatic artery. Therefore, under the diagnosis of cholangiocellular carcinoma with tumor growth in the hepatic hilar bile duct, an extended left lobectomy with caudate lobectomy and resection of the bile duct were performed. The specimen showed a whitish and firm tumor 5×4 cm in diameter in the left lobe of the liver. Tumor growth extended into the hepatic hilar bile duct from the left hepatic duct. Histological examination showed that the tumor consisted of moderately differentiated tubular adenocarcinoma. The patient is alive without recurrence 13 months after the operation. A rare but significant extension of the tumor is on the view point of surgical management of cholangiocellular carcinoma.
