Congenital fistula of the lower lip-Report of a case

Abstract

Congenital lower lip fistulas are considered to be relatively rare developmental anomalies. These fistulas are usually symmetrically situated on the vermilion portion of the lower lip as a well-marked, circular depression. Frequently, these lesions are associated with bilateral or unilateral cleft of the lip-jaw-palate.
We have experienced a case (2.7-year-old boy) of bilateral congenital fistulas on the vermilion of the lower lip. There was associated with the left cleft of lip and upper jaw. In the treatment, surgical excision was performed.
The clinical and histopathological findings of these lesions were reported and the literature was reviewed.
