[Orbital epidermoid cyst. Case report]. / Kyste épidermoïde intraorbitaire. A propos d'un cas.

Epidermoid tumors represent 1% of all primary intracranial tumors. Most of them occur intradurally in cerebellopontine angle and parasellar citerns. The intra-orbital location accounts for 4 to 5% of all primary intra-orbital tumors. We report the case of a 23-year-old girl with progressive right proptosis who had developed 6 months earlier. The tumor was removed via an external orbitotomy approach. Histology confirmed the diagnosis.
