“…The cut surface usually has a mahogany brown appearance that can be differentiated from the golden yellow surface commonly found in clear cell RCC [55]. The presence of a central stellate scar has been described as a classic feature; however, this is not specific for renal oncocytoma as it can also be seen in other tumors [56]. Despite its generally recognized benign nature, renal oncocytoma can have perinephric fat or renal vein invasion [57].…”

Purpose of reviewThe aim of the review is to provide an update on the current and evolving approaches to diagnosing the challenging clinical entity of renal oncocytoma. Recent findingsRenal oncocytoma is being increasingly recognized among patients with renal masses, and it can be found in up to 50% of benign small renal masses (SRMs) less than 4 cm. Renal oncocytomas have benign clinical biology but distinguishing them from some of the other renal masses with more malignant potential can be challenging due to overlapping imaging, histologic, and immunophenotypic characteristics. Increasing integration of various imaging modalities, histologic characteristics, cytogenetics, and molecular and metabolic signatures is helping better define and characterize renal masses.
