Abstract
We report a case of synchronous double cancer, renal cell carcinoma and colon cancer with liver metastasis, which were simultaneously resected. A 66-year-old woman was admitted to the hospital because of hematochezia. A tumor of the sigmoid colon was revealed by colonoscopy and barium enema, and a liver tumor and a left renal tumor were visualized by abdominal ultrasonography and computed tomography. Abdominal angiography showed that the tumor in the liver S3 was hypovascular and the tumor in the left kidney was hypervascular. These two tumors were diagnosed as liver metastasis of colon cancer and primary renal cell carcinoma, respectively. A sigmoidectomy and a subsegmentectomy of the liver (S3), and a left nephrectomy were performed. The sigmoid colon cancer was histologically diagnosed as moderately differentiated adenocarcinoma in stage IV, and the liver tumor was compatible with the sigmoid colon cancer. The renal tumor was alveolar type, common type and clear cell subtype of the renal cell carcinoma in stage II. The postoperative course was uneventful. The patient has been strictly followed up for two years and a half. This rare type of double cancer was also reviewed in terms of the frequency in this paper.
