Solitary colonic metastasis of renal cell carcinoma

We report a rare case of a solitary metastasis of a renal cell carcinoma which manifested as a primary colonic tumour. A 60-year-old male patient who had undergone a right radical nephrectomy 5 years previously for renal cell carcinoma, presented with a history of dyspepsia and pain in the right upper abdomen. A mass on the hepatic flexure was detected by computed tomography and colonoscopy and right hemicolectomy was performed. Postoperative histological examination revealed that the tumour was a metastatic renal cell carcinoma of the clear cell type.
