Transverse testicular ectopia (TTE) is an uncommon anatomical abnormality where both the gonads migrate toward the same hemiscrotum. Embryologically, several theories regarding the origin of TTE have been suggested including adhesion and fusion of developing Wolffian canals, aberrant gubernaculum, testicular adhesions, defective formation of the internal inguinal ring, and traction on the testis by persistent Mullerian structures. To date, about 100 cases of TTE have been reported in the literature. Herein, we report five cases of TTE operated in the Department of Paediatric Surgery, Sardar Patel Medical College, Bikaner, over a period of 5 years. All cases were in the age group of 3 months to 4 years, out of which four were diagnosed preoperatively by clinical examination and ultrasonography (USG). Two of these four cases presented with inguinoscrotal swellings and contralateral undescended testes and other two presented with absence of testes in the scrotum. One case presented with a scrotal abscess which revealed both the testes in the abscess cavity. All five cases were operated upon with herniotomy and transseptal orchidopexy and discharged successfully. TTE, although rare, has a spectrum of presentations and should be kept in mind as a possibility in cases of inguinoscrotal disorders in young age group. A preoperative USG may be helpful in conformation of diagnosis.
睾丸横过异位（TTE）是一种罕见的解剖学异常，即双侧性腺均向同一侧阴囊迁移。从胚胎学角度来看，关于TTE的起源提出了几种理论，包括发育中的沃尔夫管粘连和融合、异常的睾丸引带、睾丸粘连、腹股沟内环形成缺陷以及持续性苗勒管结构对睾丸的牵拉。迄今为止，文献中已报道了约100例TTE病例。在此，我们报告了在比卡内尔市萨达尔·帕特尔医学院儿外科5年内手术治疗的5例TTE病例。所有病例年龄在3个月至4岁之间，其中4例术前通过临床检查和超声检查（USG）确诊。这4例中的2例表现为腹股沟阴囊肿胀和对侧隐睾，另外2例表现为阴囊内无睾丸。1例表现为阴囊脓肿，脓肿腔内发现双侧睾丸。所有5例均接受疝修补术和经中隔睾丸固定术，术后成功出院。TTE虽然罕见，但有一系列表现，在年轻年龄组的腹股沟阴囊疾病病例中应考虑到这种可能性。术前超声检查可能有助于确诊。
