Abstract
Renal oncocytomas are benign, slow-growing tumours accounting for 3-7% of all solid renal neoplasms. These tumours tend to be small, unilateral and asymptomatic and are often discovered incidentally on imaging. Large oncocytomas are rare and can be difficult to distinguish from renal cell carcinoma based off clinical findings or imaging characteristics alone. Papillary adenomas are also benign renal neoplasms but arising from the renal tubular epithelium and almost always located within the cortex. We present a case of a 63-year-old Caucasian male with a large symptomatic renal oncocytoma with an incidental concurrent papillary adenoma.
