Transverse testicular ectopia with a blind ending vas deferens

Transvers testicular ectopia: A case report and literature review

•

TTE associated with PMDS is a rare case which is incidentally discovered during surgery of undescended testis.

•

Early diagnosis and treatment is necessary to prevent malignancy.

•

Follow-up for fertility assessment in the latter years should be counselled.

İntroduction

Transverse testicular ectopia (TTE) is a rare anomaly characterized by the presence of both testicles in the same hemiscrotum or inguinal region. The most common clinical findings of TTE are unilateral nonpalpable testis in the scrotum and inguinal hernia on the side of palpable testis in the scrotum. It should be kept in mind that TTE may coexist with Persistent Mullerian Duct Syndrome (PMDS). Therefore, appropriate treatment should be performed considering PMDS.

Presentation of case

Type 2 transverse testicular ectopia was diagnosed in one patient who was operated with bilateral undescended testis. He was treated with transseptal orchiopexy and excision of mullerian structures.

Discussion

In case of TTE with PMDS, optimal surgical approach with orchiopexy and excision of Müllerian duct is necessary. Intraoperative aggressive dissection of vas deferens and testicular vessels should be avoided in TTE patients. They should be closely followed because of the increased risk of malignant transformation in the postoperative period.

Conclusion

An investigation of transvers testicular ectopia should be performed in all nonpalpable undescended testis anomalies.
