Abstract

A 63-year-old man with microscopic hematuria underwent contrast-enhanced CT, which showed multiple bilateral renal masses. Percutaneous biopsy results indicated renal oncocytosis. The tumors remained unchanged for 3 years. Renal oncocytosis is a very rare tumor, but it is an established disease entity characterized by numerous oncocytic tumors and diffuse (sporadic) renal parenchymal epithelial oncocytic changes on an analysis histopathology. Although renal oncocytosis can be sporadic or part of Birt-Hogg-Dube syndrome (BHDS), our case did not associate with BHDS because of absence of lung cyst.
