A Case of Hemangiopericytoma in Nasal Cavity / 대한이비인후과학회지

Hemangiopericytomas are very rare tumor in the paranasal sinuses. It is vascular tumor derived from Zimmerman's pericytes. Sinonasal hemangiopericytoma is generally benign with a low potential for local recurrence of metastasis via the blood stream and lymphatic system. They account for about 1% of all vascular tumors. About 5% of the cases occur in the nasal cavity and usually show well-differentiated tumors. The treatment of choice is surgical resection. We present a case of nasal hemangiopericytoma treated by endoscopic resection.
