Renal cell carcinoma (RCC) is the most common type of kidney tumor. Extra-renal type has been previously reported only by few studies. In this type of RCC, cancerous tissue is present in regions other than the kidney. Here we present an isolated renal mass (RM), which was primarily diagnosed as an adrenal mass.A 52-year-old male presented with left flank pain, without weight loss, visible hematuria, and hydronephrosis was the case of this study. Computed tomography (CT) scan revealed a mass which could be either an adrenal tumor, retroperitoneal diagnosis , or a renal upper bridge tumor. The kidney mass was seen above the junction of middle and upper renal bridges . Its surrounding was liberated from the Gerota. The kidney mass was independent and encapsulated of the kidney but adhered to its surface. It was gradually released from the capsule and was extracted. The capsule beneath the mass was intact, and the site had no bleeding. The mass was then placed in endobag and removed from port ten and the entrance of port ten was suturedDuring six-month followup there was no hydronephrosis and no evidence of urinoma around the kidney.In conclusion, Rare cases of extrarenal RCC which apparently attach to the kidney Can be removed without any damage to the kidney.
