Abstract
|
|
|
Hemangiopericytoma was first described by stout and Murray in 1942 as a distinct vascular tumor composed of
spindle-shaped or rounded cells which were believed to arise from the Zimmerman's pericytes. Hemangiopericytoma
occurs wherever capillaries are founded and some of symptoms were clearly referable to the tumor site.
Althouth hemangiopericytoma is usually benign, sometimes it is difficult to differentiate from malignancy because
of its diverse clinical features. In case of malignant hemangiopericytoma, surgery, radiation therapy, and
chemotherapy played a significant role in the successful control. But as most of the hemangiopericytoma in the
nasal cavity and paranasal sinus are benign in spite of occasional local recurrence, surgical excision is the
treatment of choice. We experienced a case of hemangiopericytoma excised by sinonasal endoscopic removal.
