title: Intracranial squamous cell carcinoma arising in an epidermoid cyst.
abstract: Intracranial epidermoid cysts are uncommon benign tumors of developmental origin; malignant transformation is extremely rare. We report a case of squamous cell carcinoma arising in a chiasmatic-parasellar epidermoid cyst. Malignant change had not been suspected until histological examination revealed it.
