Transverse testicular ectopia: two case reports and literature review

Transverse Testicular Ectopia (TTE) is characterized by the presence of testis in the hemiscrotum, which can be associated with a broad spectrum of complications. It is usually manifested in pediatrics. However, on rare occasions, it can occur in adults. The diagnosis is confirmed by magnetic resonance imaging (MRI). We present two cases of Transverse Testicular Ectopia (TTE), demonstrating the significance of early diagnosis and treatment to reach optimal outcomes.

We reported two patients with common features suggestive of Transverse Testicular Ectopia (TTE). Case 1 had open surgery; his left testis was impalpable, whereas his right side was palpable. Case 2 had undergone laparoscopy surgery, and his right and left spermatic cord was discovered on the right side.

Transverse Testicular Ectopia (TTE) is classified according to clinical presentation; Type 1 is associated with inguinal hernia ranging between 40 and 50 %. Type 2 is related to persistent mullerian duct syndrome (PMDS), with a rate of 30 %. Type 3 is associated with genital anomalies and azoospermia, with a rate of 20 %. The pathogenesis is unclear. However, studies suggest that the persistence of the mullerian duct prevents normal descent of the testis. Treatment is purely dependent on early clinical presentation and surgical methods.

Transverse Testicular Ectopia (TTE) requires delicate care by the pediatric surgeon as it is considered a rare entity in such cases. Heroin, we highlight the significance of early surgical treatment and the possibility of complications if left untreated.
