Abstract
Glomangiopericytoma (GPC)/sinonasal type hemangiopericytoma (HPC) is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for <0.5% of all sinonasal tumors. This tumor differs from conventional soft-tissue HPC in location, biologic behavior, and histologic features. GPC is a borderline tumor of low malignant potential with a good prognosis after complete surgical resection. We report a case of a 20-year-old woman who presented with progressive nasal obstruction and frequent nasal bleeding and was diagnosed as GPC 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.
