目的提高对睾丸表皮样囊肿的认识,探讨睾丸部分切除术在睾丸表皮样囊肿的临床应用价值。方法收集3例睾丸表皮样囊肿病例资料,观察和分析其临床特征及其病理学特点。结果睾丸表皮样囊肿壁较光滑,界限清晰,内部无血流信号,超声可表现有:靶征(中央高回声伴周边低回声晕)或强、弱回声环交替的洋葱样改变。术后随访1～3年,无肿瘤复发及转移。结论睾丸表皮样囊肿是少见的睾丸良性肿瘤,主张采用保存患侧睾丸的肿瘤切除术。
Objective To improve the understanding of testicular epidermoid cysts and to explore the clinical value of partial removal of testicular epidural cysts in the testis. Methods Three cases of epidermoid cystic testis were collected and their clinical features and pathological features were observed and analyzed. Results The testicular epidermoid cyst wall was smooth and well-defined with no internal blood flow signal. Ultrasound could show the change of target type (central hyperechoic with peripheral hypoechoic halo) or alternating strong and weak echo rings. Follow-up 1-3 years after surgery, no tumor recurrence and metastasis. Conclusion Testicular epidermoid cyst is a rare benign tumor of the testes, advocating the use of tumor resection to preserve the affected side of the testes.
