[Kidney oncocytoma. Report of 7 cases]. / L'oncocytome du rein. A propos de sept cas.

Renal oncocytoma has some particularities in diagnosis and prognosis. We report a retrospective study performed between 1987 and 1999 at the department of Urology of Charles Nicolle's Hospital. Seven oncocytoma are found out of 120 renal carcinoma. Features at sonography or CT scan or arteriography can not suggest oncocytoma. The diagnosis is made at the pathology examination. Renal oncocytoma is a benign tumor. Conservative surgery will be performed as possible.
