Temporal dermoid - an unusual presentation

It is rare for a frontotemporal dermoid cyst to present as a discharging si nus, and even more rare for it to have intracranial extensions. Only a few cases of intraorbital extension have been reported. We report a 14-month-ol d girl who presented with all the aforementioned features. She had a tempor al dermoid with three discharging sinuses over the temporal area, lower lid , and cheek. It also had an intraorbital extension through the lateral orbi tal wall and an intracranial extension through the temporal bone. Preoperat ive computed tomography was done as there was a history of "orbital celluli tis". Excision of the cyst was done using a hemicoronal-preauricular incisi on. A lateral orbitotomy was required to remove the orbital component in co ntinuity with the rest of the cyst.
