A CASE REPORT OF SYNCHRONOLUS TRIPLE CANCER OF THE COLON AND BILATERAL KIDNEYS

Abstract

A case of synchronous triple cancer of the colon and bilateral kidneys, which were diagnosed preoperatively and resected successfully is reported. A 73-year-old man was referred to the hospital for occult blood. A cecal cancer was revealed by barium enema and colonoscopy, and bilateral renal tumors were visualized by abdominal CT. Aortography showed hypervascular tumors in the bilateral kidneys, which were diagnosed as renal cancer. After no often organ metatasis was confirmed a right hemicolectomy and right partial nephrectomy were performed simultaneously. Four weeks after the initial operation, a left radical nephrectomy was performed. Renal dysfunction was not experienced later. The cecal cancer was histologically diganosed as well differentiated adenocarcinoma, with cancer cells confined within mucosa. Pathological diagnosis of the right renal lesion was alveolar type, common type and clear cell subtype of the renal cell carcinoma, and that of the left renal lesion was papillary type, common type and clear cell subtype of the renal cell carcinoma. No lymph node metastasis or vascular invasion was noted. The postoperative course was uneventful and the patient is strictly followed up.
