ABSTRACT

Introduction: Renal oncocytoma is a benign tumor that is a rare kidney lesion. Clinically it is indistinguishable from renal cell carcinoma; when radiological studies reveal a solid kidney tumor, definitive diagnosis can only be made through histological study.
Objective: To present the case of a patient with documented diagnosis of renal oncocytoma and to carry out a review of the literature.
Methods: The clinical case of a sixty-nine-year-old woman was reviewed who presented with right incidental kidney tumor. Treatment was radical nephrectomy.
Results: Histopathological study reported renal oncocytoma measuring seven centimeters in diameter.
Conclusions: Renal oncocytoma is not common and presents more frequently in men. Its diagnosis is usually an imaging study finding and generally presents in adult patients. Main differential diagnosis is eosinophilic chromophobe renal cell carcinoma.
