Combined hepatocellular and cholangiocellular carcinoma is rare. We reported such a case here. The two cancers occurred independently in separate segments of the liver. The patient was a 56-year-old man with the chief complaint of general malaise. Two liver masses, one in the right posteroinferior segment and one in the right anterosuperior segment, were detected by using ultrasonography, computed tomography and angiography, and a right lobectomy was performed. The mass in the posteroinferior segment was diagnosed histologically as hepatocellular carcinoma, and the mass in the anterosuperior segment was diagnosed as cholangiocellular carcinoma. Reports of the resection of combined hepatocellular and cholangiocellular carcinoma are rare. The clinical course of the disease in a patient study is of interest with respect to the diagnosis and histogenesis of primary liver cancers.
