Ruptured rectal duplication cyst with classical bladder exstrophy

Journal of Pediatric Surgery, 07/23/2010

A newborn boy was brought to us, 2 hours after birth, with a mucosal–lined left hemiperineal lesion associated with classical bladder exstrophy and an anterolaterally displaced anus. Perineal anatomy was restored by excising the mucosa lined lesion. The bladder closure for classical bladder exstrophy was done at the same time. Histologically, gastric, respiratory, and small intestinal epithelia were present in the mucosa. A rectal duplication cyst that had ruptured in utero through the hemiperineum could explain the anomaly.
