title: [Renal oncocytoma: nephrectomy or tumorectomy? Description of five cases and review of the literature].
abstract: Oncocytoma is an uncommon benign tumor of the kidney. Its incidence represents 3 to 10% of all solid renal masses. This diagnosis, seldom recognized before the operation, is often revealed by anatomo-histological examination. Surgical treatment of a small tumor, ever the most benign, can be limited to enucleation or partial nephrectomy to spare renal parenchyma. When a small, solid and well-confined renal mass is discovered, the diagnosis of oncocytoma must be considered and the usual investigations (abdominal ultrasound, CT-scan...) must be completed by renal angiography to obtain as much information as possible in support of the diagnosis of oncocytoma, justifying nephron-sparing surgery.
