Abstract
-
Adrenal gland is a rare location for an oncocytic neoplasm. In English literature
less than 10 cases of adrenocortical oncocytoma have been reported. We have
experienced a case of adrenocortical oncocytoma in a 35-year-old man which was
detected incidentally during the ultra-sonographic evaluation of the abdomen for a routine
physical examination. This case did not demonstrate any clinical evidence of
adrenocortical abnomalities, such as virilization or hypertension. Grossly, the tumor was
light to dark tan on cut surface. Light-microscopic examination revealed tumor cells with
abundant lipid- sparse eosinophilic cytoplasm and occasional pleomorphic nuclei. Mitotic
figures were less than 5/50 HPFs. Tumor cells were positive for vimentin but negative
for pancytokeratin, CAM 5.2, chromogranin and synaptophysin. Ultrastructural
examination demonstrated abundant mitochondria containing occasional intramitochondrial
dense bodies or inclusions.
