Description
The 2022 WHO guidelines advise against diagnosing oncocytoma based solely on needle biopsy due to limited sampling and its similarities with malignant tumors. As a result, localized renal masses are now classified as "oncocytic renal neoplasm (ORN), not further classified," which has significant implications for clinical practice. Patients eligible for active surveillance (AS) no longer receive pathology reports indicating a benign diagnosis, leading to uncertainty in management. Additionally, the limited long-term data on ORN and the emergence of new entities within this category have raised concerns. This study aims to address these issues by providing extended follow-up on patients diagnosed with ORN from two institutions to assess the risk of metastasis.
