title: Colon metastasis of chromophobe renal cell carcinoma with sarcomatoid change.
abstract: We present a rare case of colonic metastasis of renal cell carcinoma (RCC) and review the literature. A 54-year-old male was referred to our hospital with a history of bloody stools and fever. A right kidney tumor measuring about 10 cm in diameter was found by abdominal computed tomography. Right radical nephrectomy and a right hemicolectomy with ileotransversostomy were performed. Pathological diagnosis was chromophobe RCC with sarcomotoid change involving the colon. Chromophobe RCC with sarcomotoid change is very rare.
