Colonic metastasis of a Renal Cell Carcinoma: Case report and brief review of the literature

Introduction. Colonic metastasis following curative surgery for renal cell carcinoma has rarely been described in the literature. We present a case of a 64-year-old man who previously had a left nephrectomy for renal cell carcinoma. Five months post-operatively the patient presented with microscopic intestinal bleeding and anemia. Colonoscopic surveillance revealed a metastatic lesion in the ascending colon, and a right hemicolectomy was subsequently performed. Colonic metastasis following resection for renal cell carcinoma is a rare entity, as evidenced by its lack of description in the literature. Imaging scans, such as computed tomography, have little diagnostic value and an increased medical suspicion is warranted for prompt diagnosis.
