[Epidermoid cyst of testis: benign testicular tumor].

Epidermoid cyst of the testis is very rare and accounts for approximately 1% of all testicular tumors. In the clinical examination, the testis has a palpable mass. Pathological findings usually reveal a squamous cell lined cyst, containing keratin, and the absence of appendages and teratoma element. If scrotum ultrasonography reveals a target sign suggestive of epidermoid cyst, the testis should be explored through an inguinal incision. Clamp the spermatic cord gently, and perform tumor enucleation. The frozen section is available at the time to check for any malignant cells. If no malignant cells exist, it is important to perform testis-preserving surgery, especially for young adults and children. We report two cases of epidermoid cyst. Serum beta-HCG and alpha-fetoprotein were within normal limits. We review our experience with scrotum ultrasonography and testis-preserving surgery in 2 men with epidermoid cyst to indicate when the clinical and intraoperative characteristics justify testis-preserving management.
