Sinonasal hemangiopericytoma

Abstract

Sino-nasal hemangiopericytomas are rare indolent mesenchymal tumors which slowly invade local tissue. Electronmicroscopy and immunohistochemical techniques may be necessary to differentiate hemangiopericytomas from other sarcomatous tumors. Differentiation between malignant and benign tumors poses a difficult task, therefore clinical correlation as well histological confirmation is necessary to establish a diagnosis. Due to the low incidence of distant metastasis and low mortality, surgery consisting of wide local excision is usually curative.
