Abstract

Hemangiopericytoma is an uncommon vascular tumor in the head and neck region that originates from Zimmerman’s pericytes, the small, spindle-shaped pericapillary cells. Clinical diagnosis of such a lesion is an extremely challenging task because there are very few detailed reports of such lesions and one would hardly think of a diagnosis such as hemangiopericytoma while examining a lesion. Only 15% of hemangiopericytomas are localized in the cervicofacial region, with occurrence in the infratemporal fossa is particularly exceptional. In this article, we report an unusual case of hemangiopericytoma originating from the right infratemporal area and extending into the pterygomaxillary fissure, the buccal fat pad, and the hard palate. We present a case of infratemporal fossa hemangiopericytoma that was treated by resection of the transantral approach.
