ABSTRACT

Introduction: Adrenal oncocytoma is a rare and incidental tumor without its own clinical manifestations.
Objective: To present a case of adrenal oncocytoma and its diagnostic and therapeutic characteristics.
Clinical case: 34-year-old male patient with a medical history, who presented with right lumbo-abdominal pain, without radiation or other accompanying symptoms. The physical exam was normal. The ultrasound reported a tumor of about 7 cm in diameter, located towards the upper pole of the right kidney. The adrenal origin was defined with contrast abdominal tomography. The blood levels of hormones of the adrenal cortex were normal. Total excision of the tumor was performed by conventional laparotomy. The kidney was normal. Histopathological examination reported adrenal oncocytoma and immunohistochemistry confirmed it. The patient evolved satisfactorily.
Conclusions: Adrenal oncocytoma is a rare and fortuitous tumor. Contrast abdominal tomography does not have high specificity to differentiate it from other adrenal tumors. The immunohistochemical profile of the tumor is conclusive in the definitive diagnosis.
