A Case of Renal Oncocytoma Associated with Massive Central Necrosis and Hemorrhage / 대한비뇨기과학회지

ABSTRACT

Renal oncocytoma is a rare, benign tumor, which is characterized by homogenous oncocytic cellular features without central necrosis or hemorrhage regardless of its size. Necrosis, although absence of which is emphasized in the most literatures, can rarely occur in oncocytoma. We reported here a case of renal oncocytoma in a 46-year old man, which tumor of his right kidney had exceptionally massive central necrosis and hemorrhage.
