A Case of Renal Oncocytoma with Synchronous Contralateral Renal Cell Carcinoma / 대한비뇨기과학회지

ABSTRACT

Renal oncocytoma has been recently defined histopathologically but many controversies have arised about its origin and differential diagnosis. Until the present time nearly all renal oncocytoma were considered to be benign nature, but rare cases have been reported to be metastasized. We reported a case of renal oncocytoma and synchronous contralateral renal cell carcinoma treated by radical nephrectomy on one side and enucleation on the other side.
