Abstract

Combined hepatocellular and cholangiocellular carcinoma is rare, especially the double type that occurs independently in separate segments of the liver. We report such a case that combined with rectal cancer.<br> An 84-year-old man was referred to us for abdominal pain and nausea. Abdominal radiograph revealed dilated colon and small intestine. Colonoscopy showed type 2 advanced carcinoma of the rectum. On the other hand, preoperative ultrasonography of the liver revealed two masses, one a 3.0×2.0cm tumor in segment 5, the other a 2.0×2.0 tumor in segment 7. Low anterior resection and partial hepatectomy of the two tumors were performed. The tumor in segment 5 was diagnosed histologically as hepatocellular carcinoma, and the tumor in segment 7 as cholangiocellular carcinoma. Yano et al. Reported that survival of patients with combined hepatocellular and cholangiocellular carcinoma was significantly poorer than that of hepatocellular carcinoma or cholangiocellular carcinoma alone. In the present case, the patient is still alive 17 months after the operation.
