Overview
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.[1]
Epidemiology and Demographics
Prevalence
- Renal oncocytomas account for approximately 5% of resected primary adult epithelial renal neoplasms.[1]
Age
- The incidence of renal oncocytoma increases with age; the median age at diagnosis is 55 years.
Gender
- Males are more commonly affected with renal oncocytoma than females. The male to female ratio is approximately 2 to 1.[1]
Oncocytomas make up 3% to 7% of all renal epithelial tumors.[1] They are most commonly seen in adults older than 50 years, are more common in males, and have a peak frequency in the seventh decade of life. However, these tumors rarely occur in the pediatric population.[1]
This lesion is commonly seen in patients with Birt-Hogg-Dube syndrome. These patients develop a mean of 5.3 renal tumors in their lifetime. These lesions consist mostly of chromophobe renal carcinoma and oncocytomas

Later, Klein andValensi2 identified another 13 cases as a distinctive clinical pathological entity, which they introduced in the English literature as “proximal tubular adenoma with oncocytic
features”. This specific prodrome, by convention now called “renal oncocytoma”, comprises approximately 5% of all neoplasms of renal cells in surgical series. The ages of patients with typical renal oncocytoma have varied considerably. Patients have ranged in age from 10 years to 94 years.3–6 The peak incidence of detection is in the seventh decade of life. This finding suggests that renal oncocytomas occur in a relatively older age group than in those patients with typical renal cell carcinoma (RCC), for whom the median age in large series is always approximately 55 years. However, taking into account that renal oncocytoma grows very slowly, it might start developing at an earlier age, around 30–50 years. For the cases of renal oncocytoma with reported sex, men are affected nearly twice as often as women
