Abstract
BACKGROUND

Adrenocortical oncocytoma is a rare, mostly benign, nonfunctional tumor that is typically detected incidentally. Its diagnosis is challenging because of the absence of distinctive imaging characteristics, necessitating pathological validation.

CASE SUMMARY

We present a case report of a 35-year-old woman with an adrenal mass located on the left side, where endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed after comprehensive diagnostic assessment. Our results are consistent with those of previously documented cases regarding tumor demographics and anatomical location. Given the limited number of reports on this condition, long-term follow-up is crucial to enhance our understanding of its prognosis.

CONCLUSION

For patients with adrenocortical oncocytoma, EUS-FNA can enables collection of preoperative tissue specimens leading to suitable treatment strategies.

Core Tip: The patient, a 35-year-old female, presented with an incidental finding of a left-sided adrenal mass. The nature of the mass remained uncertain following conventional imaging modalities and laboratory tests, leading us to the utilization of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The resultant pathological report confirmed the diagnosis of a nonfunctional adrenocortical oncocytoma, a rare and generally benign adrenal neoplasm. Based on this diagnosis, a tailored treatment plan was devised. This case highlights the utility of EUS-FNA in obtaining preoperative pathological confirmation, vital for customizing management strategies for individuals with nonfunctional adrenocortical oncocytomas.
