A Case of Synchronous Double Hepatocellular and Cholangiocellular Carcinomas

Abstract

A 64–year–old man with chronic hepatitis C seen for a hepatic tumor was found in ultrasonography (US) to have two liver tumors—one at segments 5 to 8 and one at segment 7. Both were shown by computed tomography (CT) to have enhanced delayed washout. Anterior segmentectomy and partial S7 resection were done. The S5 to 8 tumor was diagnosed histologically as cholangiocellular carcinoma (CCC) and the S7 tumor as hepatocellular carcinoma (HCC). Simultaneous HCC and CCC at different hepatic sites—termed double cancer—is very rare. We report this case and bibliographical comments.
