A Rare Case of Malignant Hemangiopericytoma in the Mandible

Hemangiopericytoma (HPC) is a rare malignant vascular tumor arising from mesenchymal cells with pericytes differentiation. HPC represents only 1% of the adult vascular neoplasms. This tumor usually occurs in the limbs and pelvis with only 5% in the oral cavity and pharynx. The histological appearance does not reliably predict the biologic behaviour of the tumor. Due to chances of late recurrence and metastasis, several studies recommended long-term follow-up. A case of malignant hemangiopericytoma in the mandible in a 24 years old female with 7 years follow up have been reported in this article.
