Epidermoid Cyst of the Testis: Sonographic Characteristic Appearance

Intratesticular epidermoid cysts are rare, benign, well-defined, and solitary keratinized intratesticular lesions. They usually present as a painless, discrete, and firm swollen area before being diagnosed. Preoperative diagnosis of epidermoid cysts is often difficult. Sonography is a useful imaging modality in the preoperative assessment of testicular lesions. Although it is difficult to distinguish epidermoid cysts from germ cell tumors, certain sonographic characteristics such as the classical “onion-peel” appearance, the negative tumor markers, and the underlying symptoms should raise the suspicion of epidermoid cysts.

[Non-germinal tumours of the testicle]

The great variety of non germinal testis tumours and their rarity explain the difficulties of a specific therapeutic management. The analysis of the most important varieties of tumours allows identifying an overall trend in both diagnosis and therapy.

Testicular Epidermoid Cysts

Testicular epidermoid cysts are benign tumors that represent only 1% of all testicular tumors. This tumor presents as a palpable mass within the testicle. High-resolution sonography can help provide a presurgical diagnosis due to the tumor’s unique sonographic appearance of a “bow tie” echogenicity. This bow tie pattern is formed by the deposition of keratin in layers by the lining of the cyst. A preoperative sonographic diagnosis of a testicular epidermoid cyst can lead to testicle-sparing surgery in healthy, young males due to the benign nature of this tumor.

Epidermoid cyst of the testis in an adolescent: Case report and review of the evolution of the surgical management

Epidermoid cyst, a tumorlike lesion, is a rare benign testicular tumor with typical, distinctive ultrasonographic appearance. When the preoperative features are highly suggestive of epidermoid cyst, testicular sparing surgery after strict oncologic guidelines is warranted. The authors report a case of a preoperatively suspected epidermoid cyst in an adolescent and review the literature concerning the changing paradigm of management.
