Detection and Treatment of Persistent Mullerian Duct Syndrome With Transverse Testicular Ectopia

The coexistence of persistent Mullerian duct syndrome (PMDS) with transverse testicular ectopia (TTE) is extremely rare. Due to a lack of distinctive clinical features in the early stages, PMDS coexists with TTE is usuallydiagnosed when patients are examined for other diseases,including cryptorchidism and inguinal hernia. We present a case of a 51-year-old man who presented with a recurrent left indirect inguinal hernia for 2 years and right congenital cryptorchidism. The patient was diagnosed as PMDS with TTE by preoperative magnetic resonance imaging and underwent laparoscopic resection of the right transverse ectopic testis and Mullerian duct residues.
