Surgical management of a locally invasive renal cell carcinoma in an ectopic pelvic kidney

The coincidence of renal cell carcinoma in an ectopic kidney is a unique phenomenon. We report a case of 55 years old male patient who presented with backache and accidentally discovered ectopic kidney with an upper polar mass. Preoperative assessment was done with pelviabdominal sonography and triphasic renal CT. Our patient underwent radical nephrectomy through a midline incision with unexpected vasculature encountered intraoperatively. According to our knowledge, only eight cases of pelvic kidney tumors have been reported in the literature and this case is unique with its complex vascular structure.
