title: Glomangiopericytoma of nasal cavity.
abstract: Glomangiopericytoma/sinonasal type hemangiopericytoma is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for less than 0.5% of all sinonasal tumors. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behaviour and histologic features. Glomangiopericytoma is a borderline low malignancy tumor with a good prognosis after complete surgical resection. We report a case of 60-year-old woman who presented with progressive nasal obstruction and frequent nasal bleeding and was diagnosed as glomangiopericytoma on histopathological and immunohistochemistry findings. Histological characteristics, differential diagnosis and prognosis of this tumor are discussed in this article. This case has been reported because of its rarity and an array of differential diagnosis.
