Simultaneous Double Cancers of Liver Metastasis of Desending Colon Cancer and Hepatoma in a Successful Double Excision Case

The patient, male aged 64 years old, came to our hospital with complaint of the left abdominal pain persisted for 1 year. He was then admitted under the diagnosis of desending colon cancer by barium enema Xray. A tumor, 3 cm in diameter, was found in the liver S3 area by US and CT examination, and abdominal section was performed under the diagnosis of liver metastasis. During the operation, a small tumor, 7 mm in diameter, was recognized in the margin of the liver S2 area, and then excision of lateral area of the left lobe, left hemicolectomy and cholecystectomy were performed. On the pathohistological findings, the tumor in S3, 3 cm in diameter, was hepatoma, and the tumor in S2, 7 mm in diameter, was mucinous liver metastasis cancer of desending colon cancer. A double cancer case in both colon and liver is relatively frequently encountered at autopsy but the operated case has been few. Furthermore, successful double excision has rarely been reported. This case was reposted here, because a case in which liver metastasis and hepatoma were simultaneously found and excised has never been described in the literatures concerned.
