# Use of intraoperative ultrasound in a benign epidermoid cyst-like tumor lesion with testicular preservation: Case report

## TL;DR

A case report shows how intraoperative ultrasound helped preserve a testicle during surgery for a benign cyst in a teenage boy.

## Contribution

Demonstrates the clinical utility of intraoperative ultrasound in preserving testicular function during benign cyst surgery.

## Key findings

- Intraoperative ultrasound and freezing biopsy confirmed a squamous cell cyst in a 17-year-old male.
- Use of imaging allowed testicle preservation instead of orchiectomy, improving hormonal and reproductive outcomes.
- Testicular epidermoid cysts are benign and often do not require removal of the entire testicle.

## Abstract

Epidermoid cysts are rare benign lesions in adolescence, commonly presenting as slow-growing, nonpalpable masses lined with squamous epithelium, filled with keratinized material. Testicular ultrasound is the study of choice for the diagnosis of these lesions, and its intraoperative use has been shown to be beneficial for the patient's hormonal and reproductive prognosis. In this study, we present the case of a 17-year-old adolescent male who came to the urology office with a sensation of mass in the right testicle with negative tumor markers. Tumor resection was performed with intraoperative ultrasound guidance and freezing biopsy, with confirmation of the diagnosis of squamous cell cyst, which allowed the decision to preserve the testicle. Epidermoid cysts are benign testicular lesions that commonly do not require orchiectomy. The correct imaging identification with pre- and intraoperative ultrasound is acquiring an important role in the management of these cases by allowing testicular preservation decisions, which offers a better hormonal and reproductive prognosis for patients.
