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. Although 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. (J Clinical Otolaryngol 2000;11:148-152)
