Overview
Renal oncocytomas are relatively rare, and benign tumors.
Classification
There is no classification system established for renal oncocytoma.
Pathophysiology
On gross pathology, tan or mahogany brown, well circumscribed, and central scar are characteristic findings of the tumor of renal oncocytoma. On microscopic histopathological analysis, oncocytes and large eosinophilic cells are characteristic findings of renal oncocytoma.[1]
Causes
There are no established causes for renal oncocytoma.
Differential Diagnosis
Renal oncocytoma must be differentiated from renal cell carcinoma, metanephric neoplasms, and renal leiomyoma.
Epidemiology and Demographics
The incidence of renal oncocytoma increases with age; the median age at diagnosis is 55 years. The male to female ratio is approximately 2 to 1.[2]
Risk Fctors
There are no established risk factors for renal oncocytoma.
Screening
According to the the U.S. Preventive Service Task Force (USPSTF), there is insufficient evidence to recommend routine screening for renal oncocytoma.[3]
