Hemangiopericytoma is a rare vascular tumor arising from pericytes and occurs very rarely in sinonasal region. A 48-year-old man with sinonasal mass presented with nasal obstruction and occasional epistaxis. Nasal endoscopy showed a readily bleeding mass in the left nasal cavity. Endoscopic removal of the mass was done. The histopathology came out to be hemangiopericytoma. The patient was kept on follow-up, and no metastasis or recurrence was seen in last 1 year. Hemangiopericytoma is a very rare vascular tumor. Surgery is the mainstay treatment of choice. A long-term follow-up is needed after surgery to rule out recurrence and metastasis.
