Abstract
The case pertains to a 66-year-old man that was referred to our hospital for close inspection and treatment purposes upon being indicated as having a hepatic mass by a local doctor. Upon abdominal ultrasonography, a mass lesion was observed in three locations: the liver S6 and the cranial side of S7, as well as the caudal side of S7; wherein, the S6 mass was observed to be a mass having contrast enhancement in the surrounding region thereof, while the mass on the cranial side of S7 and caudal side of the S7 were observed as masses with poor contrast enhancement. The patient was diagnosed to have combined hepatocellular-cholangiocarcinoma upon a biopsy conducted on the S6 mass, leading to posterior segment resection of the liver being carried out. The S6 mass was found to be combined hepatocellular-cholangiocarcinoma upon histopathologic examination, while the masses on the cranial side of S7 and caudal side of the S7 were hepatocellular carcinomas. The patient is still alive today approximately seven years following surgery. Cases in which both combined hepatocellular-cholangiocarcinoma and hepatocellular carcinoma are both present at the same time in different locations of the same liver, a so-called double cancer, are rare. We herein report on our experience with an excision example of this case, with the addition of some bibliographical considerations.
