[Haemangiopericytoma of the nasal cavity as a cause of recurrent epistaxis--case report].

A case of haemangiopericytoma of the nasal septum in 73-year-old female admitted to the Department of Otolaryngology of Wroclaw Medical University with a history of recurrent epistaxis and progressive right monolateral nasal respiratory obstruction is reported. On admission presented smooth, cyanotic, easily bleeding lesion in the nasal cavity on the right. Nose CT scans identified presence of a soft-tissue mass arising from the nasal septum. She was treated with a complete surgical resection of the mass. The diagnosis was established based on the careful histopathological examination. Haemangiopericytomas are rare soft-tissue neoplastic lesions, occurring mainly in adults, originating from pericytes and primarily arising in the lower extremities and retroperitoneum. Haemangiopericytomas of head and neck are very unusual and comprise about 15 to 30%; of these, approximately 5% occur in the sinonasal area. Authors have presented etiology, symptomatology, histopathological features, differential diagnoses, diagnostic and therapeutic management. Malignant and benign clinical course have been described.
