异位中肾管囊肿合并异位睾丸恶变1例报告并文献复习

Ectopic mesonephric duct cyst with ectopic testicular malignancy:A case report and literature review

目的:报告1例罕见异位中肾管囊肿合并异位睾丸恶变病例,提高对本病的诊治水平。方法:回顾分析异位中肾管囊肿合并异位睾丸恶变的病例的临床资料,结合国内外相关文献,探讨异位中肾管囊肿合并异位睾丸恶变的发病机制、诊断及治疗。结果:经腹切除巨大囊肿及右侧异位恶变睾丸,左侧隐睾行下降固定,病理示"右异位中肾管囊肿,右侧异位睾丸精原细胞瘤",随访1年无转移。结论:异位中肾管囊肿合并异位睾丸恶变极为罕见,影像学检查可协助诊断,但最终需病理确诊,应早期行手术切除。后续治疗取决于隐睾恶变的病理类型及分期。

[ Abstract ] Objective ： To report a rare case of ectopic mesonephric duct cyst with ectopic testicular malignancy and improve the diagnosis and treatment of the disease. Methods ： We retrospectively analyzed the clinical data of a case of ectopic mesonephric duct cyst with ectopic testicular malignancy, reviewed relevant literature at home and abroad, and investigated the pathogenesis, diagnosis and treatment of the disease. Results ： A large cyst and the right ectopic malignant testis were removed via abdominal incision, and the left undescended testis was lowered into the scrotum. Pathological examination confirmed the lesion to be right ectopic mesonephric duct cyst with right eetopic testieular seminoma. No metastasis was found during a year of follow-up. Conclusion ： Ectopic mesoneph- ric duct cyst with ectopic testicular malignancy was a rare disease. Imaging examination contributes to its diagnosis, but it has to be confirmed by pathology. Surgical removal should be performed as early as possible and follow-up treatment depends on the pathologic type and stage of ectopic testicular malignancy. Natl J Androl, 2013, 19 （11） ： 1016-1019
