Objective:
Testicular epidermoid cysts are rare and can be clinically misleading with other testicular neoplasms. We describe a case of epidermal cyst of the testis, with the aim to contribute to the clinicopathological knowledge of this entity.
Methods:
A 24-year-old caucasian man presented with a self-detected right testicular mass. Ultrasound features were consistent with solid tumor. He underwent an inguinal radical orchyectomy.
Results:
An intraparenchymal cyst measuring 1,4 cm was observed, covered by epidermal epithelium with no other skin components. Adnexal testicular pulp was normal.
Conclusions:
When a preoperative diagnosis is made, a conservative treatment is recommendable, including frozen sections analysis of the cyst and adjacent testicular parenchyma to rule out a coexistent intratubular germ cell neoplasia.
