Abstract
An extremely rare case of congenital midline sinus of the upper lip in a 12-year-old girl is presented. The sinus had a pit-like orifice in the midline philtral area with a duct extending 4 mm posterosuperiorly. It was excised by extraoral elliptical incision. Histopathological examination disclosed that the duct was covered by a stratified squamous epithelium with sebaceous glands. Twelve cases of this rare disease have previously been reported.Entities:
