A rare case report of a congenital fistula of the upper lip in a 12-year-girl is presented.
The patient had a midline, pit-like opening superior to the vermilon border of the upper lip.
It was excised by an ellipticalincision in the upper lip. The tract was resected through an intra-oral midline upper labial incision.
Histological examination revealed that the fistula consisted of keratinized stratified squamous epithelium with sebaceous glands.
