Broad, Recurrent Nasal Dermoid Cyst: A Challenging Task.

Nasal dermoid sinus cyst is a rare congenital midline anomaly. The embryological origin is different from the dermoid cysts seen in other parts of the face. Nasal dermoid sinus cysts constitute 1% to 3% of all dermoid cysts and 11% to 12% of head and neck dermoid cysts. While most lesions are detected in the first 3 years, in some cases they may not be noticed until later years. Delay in diagnosis increases recurrent infections, airway obstruction and intracranial complications. The authors present a 34-year-old patient with a broad nasal dermoid cyst who had previously undergone external rhinoplasty for a nasal dermoid cyst but relapsed after 5 months.
