## Abstract

Anorectal malformations (ARMs) is a congenital abnormality that is commonly seen in newborns without a normal or ectopic anal opening. H-type fistula is a rare subtype and is commonly diagnosed in females after a history of passing stool from the vagina which may be the first and only sign of an underlying ARM which necessitates further diagnostic modalities, treatment, and follow-up. These children may have a normal anal opening. We report on a rare case of rectovaginal fistula presenting with a left labial abscess.
