Introduction:
Testicular tumors are usually managed by radical orchiectomy because of the high incidence of malignant lesions. Epidermoid cyst of the testis is a rare benign tumor, and its differential diagnosis from malignant testicular tumors is difficult.
Materials And Methods:
The clinical records of seven patients who attended our hospital with testicular epidermoid cysts were reviewed. Preoperative evaluation consisted of testicular ultrasonography in 6 patients, and magnetic resonance imaging in 4 patients. A peroperative biopsy was performed in four patients.
Results:
Ultrasonographic appearance was specific for diagnosis of epidermoid cyst in 80% of patients. Pathological diagnosis was made in all biopsies taken during surgery. Conservative management was (tumorectomy or partial orquidectomy) performed in 6 patients (85%).
Conclusions:
Preoperative imaging findings, gross characteristics of the lesion, and peroperative biopsy results provide adequate information to attempt testis-sparing surgery instead of radical orchiectomy.
