Abstract

The infratemporal fossa is the deep retromaxillary space that corresponds to the inferior aspect of the middle cranial fossa. Although tumors of the infratemporal fossa are uncommon, a variety of neoplasms have been reported to involve this area. They include nasopharyngeal carcinomas, juvenile angiofibromas, and adenoid cystic carcinomas. Rarely, a pleomorphic adenoma (PA) is seen, although carcinoma ex PA, a malignant tumor of the salivary glands arising in a preexisting PA, has not been reported in the literature. Factors affecting the malignant transformation of a PA include tumor recurrence, the age of the preexisting tumor, radiation therapy, advanced age of the patient, and tumor size. Here, we present the case of a 40-year-old woman with carcinoma ex PA of the infratemporal fossa with its associated computed tomography and magnetic resonance imaging findings.
