Answer:
Dermoid cysts contain epithelium and adnexal structures. They are typically found in the lateral brow and in the midline of the nose or neck. Large lesions with intraorbital extension may cause exopthalmos. Midline nasal dermoids may present as a small pit near the radix but may extend into the septum, cribiform plate, and dura, and should therefore be investigated with CT scanning before surgery. Dermoid cysts of the neck have presented with large masses causing respiratory obstruction soon after birth, requiring early surgical intervention. Extirpation of the lesions may require a craniofacial approach in order to remove the skeletal extension of the cysts.
