Abstract

Introduction

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.

Presentation of case

A 7 year old Caucasian 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.

Discussion

The prevalence of lower lip sinuses has been estimated to be about 0.00001% of the white population. Upper lip sinuses are even more uncommon. To date, there have been several case reports of upper lip sinuses and fistulas. A total of 55 cases was found upon reviewing the English literature. No similar cases were reported in Jordan. Different presentations are mentioned in this review. Several embryologic theories are presented.

Conclusion

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.
