title: Hemangiopericytoma associated with multiple keratocystic odontogenic tumors in an adolescent patient: a case report.
abstract: Hemangiopericytoma, initially described by Stout and Murray in 1942 (1), is a rare vascular tumor arising from mesenchymal cells with pericytic differentiation. Hemangiopericytomas usually occur in the 5th decade of life and account for 3-5% of all soft tissue sarcomas and 1% of all vascular tumors (2). The tumor usually occurs in the limbs, pelvis, or head and neck region; 15-30% of all hemangiopericytomas occur in the head and neck (2,3). Here we present a case of hemangiopericytoma of the submandibular region with keratocystic odontogenic tumors in an adolescent patient.
