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.
