We experienced a rare synchronous double cancer: Cholangiocellular carcinoma with tumor thrombus in the teres hepatis and ureter carcinoma. A 71 old man admitted for bloody urine was found in computed tomography to have a hypovascular tumor 5 cm in diameter in segment 4 of the liver. Percutaneous trashepatic cholangiography showed tapered abrupt obstruction of the left hepatic duct. Portgraphy showed abrupt obstruction of the left portal vein. Ureterography showed a protruding tumor of the right ureter. We conducted extended left lobectomy with caudate lobectomy, combined resection of the portal vein, right nephrectomy and ureterectomy. Pathological study of the specimen showed moderately differentiated adenocarcinoma of the liver and transitional cell carcinoma of the ureter. Tumor thrombus of the portal vein extended to the teres hepatis. Postoperative course was uneventful, but the patient died of multiple liver metastasis 12 months after operation.
