Congenital midline sinus of the upper lip: a case report
Congenital pits of the lip are uncommon and may be associated with conditions such as Van der Woude syndrome. Isolated lip pits are extremely rare developmental defects.
The present case has been reported in the International Journal of Surgery Case Reports.

A 7-year-old girl presented to plastic surgery clinic in Jordan University academic hospital complaining of an upper lip pit that has been present since birth.

It was associated with a single episode of whitish discharge. On examination, an isolated upper lip midline sinus was found. She is otherwise fit and healthy. Surgical excision was curative with good cosmetic outcome.

Major takeaway:-
- Upper lip sinus formations are rare developmental events, and the pathogenesis of these lesions still needs further evaluation.

- Simple surgical excision is the treatment of choice.
