Cureus. 2024 Aug 17;16(8):e67058. doi: 10.7759/cureus.67058. eCollection 2024 Aug.

Abstract

Pheochromocytomas are rare adrenal medulla tumors originating from chromaffin cells, accounting for 10% of primary adrenal neoplasms. Oncocytic variants of pheochromocytomas are rare and have been reported in only 150 cases. This report describes the case of a 60-year-old female who arrived with a non-functional adrenal tumor. This case report emphasizes the importance of a comprehensive histological and immunohistochemical study for diagnosing this rare diagnostic entity and its potential diagnostic pitfalls.

Keywords: adrenal oncocytoma; adrenocortical oncocytomas; oncocytic neoplasm; oncocytic pheochromocytoma; oncocytic tumors.
