Abstract
A 58-year-old man complaining of a right hypochondrium tumor visited our hospital. An abdominal computed tomography examination revealed two tumors (7 cm and 11 cm in diameter) in the right lobe of the liver, a third tumor (3 cm in diameter) in the lateral segment of the liver (S2), and a fourth tumor (7 cm in diameter) in the upper part of his right kidney. An abdominal angiography showed that the first two tumors accounted for most of the right lobe of the liver and were contrasted non-uniformly, a hypervascular tumor in the upper part of the right kidney was also observed. Since the patient's tumor marker (CEA) level was high (2580 ng/ml), we suspected liver metastasis from colon cancer and performed a colonoscopy. A type 2 tumor filling 2/3 of the inside of the sigmoid colon was found. Based on the above-mentioned findings, we performed an operation under a diagnosis of synchronous double cancer of the sigmoid colon with liver metastses and cancer of the right kidney. The right lobe of the liver was resected, and an S2 wedge resection of the liver was performed. The right kidney and the sigmoid colon were also resected simultaneously. Synchronous double cancer of the colon and kidney is very rare. A review of 27 cases, including the present case, is presented.
