# Adrenocortical oncocytic neoplasms: a case report

## TL;DR

This paper reports a rare case of adrenocortical oncocytic neoplasms, a type of adrenal tumor, diagnosed and treated successfully with no recurrence after surgery.

## Contribution

The contribution is a detailed case report of a rare adrenocortical oncocytic neoplasm diagnosis and successful treatment outcome.

## Key findings

- ACONs were confirmed through postoperative pathological analysis.
- The patient showed no tumor recurrence or complications after 11 months of follow-up.

## Abstract

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.
