Preoperative evaluation of pelvic kidney renal cell carcinoma with 64-slice CT and 3D-CT angiography

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.

Primary extra-renal clear cell renal cell carcinoma masquerading as an adrenal mass: A diagnostic challenge

We present the first case of a nonmetastasizing renal cell carcinoma (RCC) masquerading as an adrenal mass, in the presence of normal bilateral native kidneys, in a young adult. The possibility of this mass developing in a supernumerary kidney was ruled out, since no identifiable renal tissue, pelvis or ureters was seen within the mass, nor was any separate systemic arterial supply to the mass seen. The diagnosis of extra-renal clear cell RCC was based on cyto-morphological features, further confirmed by immunohistochemistry findings. The origin of this extra-renal clear cell renal cell is proposed to be from the mesodermal embryonic rests.
