Crossed testicular ectopia (CTE) is a rare anomaly, characterized by migration of one testis towards the opposite inguinal canal. Presented here is a case of crossed ectopia of the right testis, treated by extraperitoneal transposition of the gonad and right orchiopexy. Embriology and surgical findings suggest that CTE is a common consequence of many unclear ethiologic factors, specially mechanical ones, and can be associated with Muller duct persistence. Review of literature suggests a classification of CTE into 3 types: I--associated with inguinal hernia alone; II--associated with persistent mullerian remnants; III--associated with other anomalies without mullerian remnants. Treatment includes transeptal orchiopexy or extraperitoneal transposition of the testis, research for mullerian remnants and other anomalies, and long term postoperative follow-up, due to the risk of becoming malignant.
交叉性睾丸异位（CTE）是一种罕见的异常情况，其特征为一侧睾丸向对侧腹股沟管迁移。本文介绍了一例右侧睾丸交叉异位的病例，采用性腺腹膜外移位术和右侧睾丸固定术进行治疗。胚胎学和手术发现表明，CTE是许多不明病因因素（特别是机械性因素）的常见后果，并且可能与苗勒管残留有关。文献综述表明，CTE可分为3型：I型——仅与腹股沟疝相关；II型——与苗勒管残留持续存在相关；III型——与无苗勒管残留的其他异常相关。由于存在恶变风险，治疗包括经中隔睾丸固定术或睾丸腹膜外移位术、探查苗勒管残留及其他异常情况，以及术后长期随访。
