A case of a nasal dermoid presenting as a median upper lip sinus.

Nasal dermoids are uncommon developmental abnormalities. Median upper lip fistulas are even rarer and recognized as a separate pathology. The authors present the unusual case of a child with a sinus on the philtrum of the upper lip and a sinus tract passing all the way to the anterior skull base through the nasal septum. The authors propose that nasal dermoids and medial upper lip fistulas have a common aetiology, and may be the same entity. The authors suggest they should all be managed like nasal dermoids and have MRI scanning prior to theatre. If the lesion extends into the nose, excision by external rhinoplasty is the preferred option.
