title: [Sinonasal-type hemangiopericytoma].
abstract: Sinonasal-type hemangiopericytomas are rare tumors believed to derive from perivascular modified smooth muscle cells. They have a predilection for the nasal cavity and paranasal sinuses, where they grow as polypoid masses. Affected patients experience epistaxis, nasal obstruction, sinusitis and bone erosion along with a wide array of other nonspecific findings. The overall excellent survival is achieved with complete surgical excision. Up to 30% of the cases develop recurrence, often many years after initial surgery. Malignant behavior is uncommon. A case of a 59 year old woman is presented.
