To describe a case of epidermoid cyst of the testis, a rare lesion that warrants surgical exploration to confirm the diagnosis since its echo patterns are characteristic but not pathognomonic.
METHODS/RESULTS: 10 years earlier the patient had noticed an asymptomatic swelling of the right testis which did not cause infertility since he had two children over the last 6 years. Tumor markers AFP, BHCG and LDH fell within the normal ranges. Ultrasound evaluation with a high resolution 7.5 Mhz transducer revealed a 4 x 3.5 x 3.2 cm testicular mass surrounded by atrophic parenchyma. The patient underwent radical inguinal orchidectomy.
Epidermoid cyst is the benign variety of testicular teratoma. Two different forms exist: simple and mixed. Malignant components are present in the latter form. If the simple form is identified before substitution of the testicular parenchyma occurs, testis sparing surgery is justified; otherwise radical orchidectomy with inguinal exploration is indicated.
描述一例睾丸表皮样囊肿病例，这是一种罕见病变，因其回声模式具有特征性但并非特异性，故需手术探查以确诊。
方法/结果：患者10年前注意到右侧睾丸有无症状肿胀，由于其在过去6年育有两个孩子，故未导致不育。肿瘤标志物甲胎蛋白（AFP）、β人绒毛膜促性腺激素（BHCG）和乳酸脱氢酶（LDH）均在正常范围内。使用7.5兆赫高分辨率探头进行超声评估，发现一个4×3.5×3.2厘米的睾丸肿物，周围为萎缩的实质组织。患者接受了根治性腹股沟睾丸切除术。
表皮样囊肿是睾丸畸胎瘤的良性类型。存在两种不同形式：单纯型和混合型。后一种形式存在恶性成分。如果在睾丸实质组织被替代之前识别出单纯型，保留睾丸手术是合理的；否则应进行根治性睾丸切除术并进行腹股沟探查。
