@entity5 , composed of eosinophilic, mitochondria-rich cells, can occur in several locations throughout the body. These @entity5 can occur in the adrenal cortex and are rarely malignant. We report a case of a @entity1 presenting with an incidental adrenal mass which was later diagnosed as a oncocytic @entity1636 (OAN). The @entity1 is a 53-year-old @entity1 found to have a 7.2   cm right adrenal mass, incidentally found by computed tomography (CT). After metabolic workup was negative, a right robotic adrenalectomy (RA) was performed. Pathologic analysis revealed clusters of large cells with abundant eosinophilic and granular cytoplasm, consistent with OAN. This pathology is rare, with only about 150 cases described in the literature. It occurs in females 2.5 times more frequently and more commonly on the left side. Diagnosis is usually made by imaging criteria, typically with CT or magnetic resonance imaging (MRI). Treatment is generally surgical, since OAN can be malignant in some cases. Differentiation between benign and malignant OAN is done based on the Lin-Weiss-Bisceglia criteria and can be difficult. If @entity5 is diagnosed, recurrence is common and close surveillance should be performed.
