Crossed fused renal ectopia (CFRE) is a rare congenital renal abnormality. It is usually diagnosed incidentally by imaging. Herein we report a 53-year-old patient with renal cell carcinoma of CFRE. He was successfully treated with an open partial nephrectomy and was discharged without any complications. Furthermore, we review similar cases of CFRE to identify the clinical features and surgical technique.
