Epidermoid Cyst of the Testis

Epidermoid cyst of the testis is a benign encapsulated testicular tumor composed of epidermal cells.

Epidemiology

Etiology of Epidermoid Cysts of the Testis

Epidermoid cysts of the testis are caused by scattered epidermal cells or teratoma with exclusive epidermal differentiation.

Pathology of Epidermoid Cysts of the Testis

Epidermoid cysts of the testis are sharply circumscribed grayish-white to yellowish encapsulated benign tumors. The tumor capsule consists of connective tissue with keratinizing squamous epithelium, the interior of an amorphous mass.

Diagnosis

Ultrasound of the testis reveals a sharply defined echogenic tumor.

Treatment

Inguinal incision and exposure of the testis: depending on size and preoperative suspicion for a benign tumor, perform either organ-preserving resection with frozen sections (Heidenreich et al., 1995) or radical orchiectomy.
