Nasal dermoids in children.

Nasal dermoids are uncommon. The term nasal dermoid, nasal epidermoid and nasal sebaceous cyst are used interchangeably by clinicians. The clinical signs and the surgical findings of 67 cases are reported. No difference was found to distinguish the nasal dermoids from the nasal epidermoid lesions, apart from the presence of hair in the cyst or sinus. The term 'nasal dermoid' should be used to include both lesions and qualified by 'simple' or 'complex' depending on the surgical extent of the tissues involved.
