title: [Low-grade oncocytic adrenal carcinoma].
abstract: OBJECTIVE
  To report a case of left adrenocortical neoplasm.
  
  
  METHODS
  A case of left adrenocortical neoplasm measuring 16 x 10 x 7 cm in a 47-year-old male is presented. After puncture biopsy, a left adrenalectomy through the abdominal approach was performed.
  
  
  RESULTS
  Immunohistochemical studies showed reactivity to the anti-Melan-A A103 antibody, suggesting an adrenal origin of the tumor cells. Strong reactivity to the mES-13 mitochondrial antibody, which is characteristic of oncocytes, made ultrastructural studies unnecessary.
  
  
  CONCLUSIONS
  In this type of tumor, an increased mitotic activity and necrosis are suggestive of malignancy. Despite the foregoing, most of this type of lesions are clinically benign and nonfunctioning.
