A 59-year-old man undergoing left radical nephrectomy for renal cell carcinoma had systemic interferon-α therapy initiated for lung and pancreas metastasis, and resection for the 2 metastatic bone lesions. He experienced melena 5.5 years after nephrectomy. Examination including barium enema and colonoscopy showed a tumor on the descending colon with a hypervascular feature through computed tomography (CT) scanning. Biopsy showed necrosis and granulation without malignant findings. We partially resected the colon and pericolonic lymphnodes. Small nodules were found at the omemtum and mesenterium of the small intestine, and some were resected. Postoperative histopathological findings showed that both tumor and nodules had metastasized from renal cell carcinoma. The patient remains alive one year after colonic resection. Metastatic tumors from renal cell carcinoma to the colon are rare, and only 7 cases have been reported in the Japanese literature over the last 15 years.
