[Labial recurrent swelling revealing median congenital upper-lip fistula].

Midline upper-lip fistulas are an extremely rare variant of congenital facial malformations. Less than 30 cases have been reported in the literature since 1970. We report the case of a 2 and a half-year-old girl presenting with a median congenital blind fistula of the upper lip, without any relation with the oral cavity. A recurrent swelling of the upper lip was the main symptom. Complete surgical excision of the cyst or of the fistulous tract must be obtained to avoid recurrence.
