Abstract
- Hemangiopericytoma is an uncommon vascular tumor described first by Stout and Murray in 1942. These tumors arise from Zimmerman's pericytes, which are found outside capillaries and postcapillary venules. Although hemangiopericytomas are well characterized, many controversies still exist regarding their malignant potential and management. The hemangiopericytomas usually present as rapidly growing, painless masses. They are usually detected because of their rapid growth, or become symptomatic secondary to compression of adjacent structures. Pain occurs with local invasion or bony metastasis. The hemangiopericytoma in the nasal cavity and paranasal sinus often has local recurrence but appears to be a lower grade malignancy. And wide surgical excision is the treatment of the choice. We report a case of hemangiopericytoma occurred in the right nasal cavity and paranasal sinus treated by median maxillectomy via lateral rhinotomy incision.
