[Bilateral multiple renal oncocytoma. Case report and review of the literature].
The authors report the case of a 75-year-old man presenting with prostatic syndrome. Ultrasound assessment revealed multiple bilateral solid renal lesions that were confirmed by computed tomography. It was decided to perform bilateral percutaneous biopsy of the masses. The histological diagnosis was that of oxyphilic adenoma with an oncocytic appearance compatible with oncocytoma. In view of the histology and the multiple lesions, none of which was larger than 5 cm, it was decided to perform watchful waiting which did not reveal any change in size with a follow-up of 4 years. Although renal oncocytoma is relatively frequent, only 19 cases of bilateral multiple renal oncocytomas have been published in the world literature. The authors present a new case and review the current state of this entity.
