Median cleft of the upper lip associated with a mass: a rare case.

Median cleft lip is a midline vertical cleft through the upper lip. This is a very rare anomaly described in the literature. Median cleft lip is caused by the failure of fusion of the medial nasal prominences. In this case report, a 4-month-old boy with a median cleft associated with a mass of the upper lip is presented. The patient has no other anomalies of the nose or alveolus. The patient has normotelorism. A Z-plasty technique was used on the skin of the base of the columella. A vertical excision of the cleft with muscle approximation was performed on the white roll and the wet-dry border of either side of the defect of the upper lip. Postoperatively, the patient had a satisfactory result. The incisive scars were not visible. Cupid's bow was appropriately aligned, and the height of the upper lip was equal on both sides.
