Transverse testicular ectopia in a newborn with transposition of the great arteries: A unique case report

Transverse testicular ectopia (TTE) is an extremely rare though well-documented congenital anomaly. In males with a 46XY karyotype, it is characterised by the herniation of both testes and part of the Müllerian organs into a single processus vaginalis. TTE is one of the three main clinical presentations of persistent Müllerian duct syndrome (PMDS). Transposition of the great arteries (TGA) is another rare congenital anomaly and severe cardiac condition. We present the likely first reported case of TTE with an accompanying malformation of TGA in a newborn.
