Adrenocortical oncocytic neoplasms: a case report.

Adrenocortical oncocytic neoplasms (ACONs) are very rare in adrenal cortical tumors. One case was reported in this paper. During the physical examination, a soft tissue density shadow was about 6 cm × 5.7 cm in the right adrenal gland. A preoperative diagnosis was adrenal pheochromocytoma with concurrent laparoscopic resection of the right adrenal tumor. Postoperative pathological results rewarded the adrenal cortical oncocytic neoplasms ACONs. After 11-months of postoperative follow-up, the patient had no signs of tumor recurrence and related complications.
