Glomangiopericytoma of Nasal Cavity: A Rare Sinonasal Perivascular Tumor

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 behavior, and histologic features. Glomangiopericytoma is a borderline low malignancy tumor with a good prognosis after complete surgical resection. A 42-year-old man presented with progressive nasal obstruction and frequent nasal bleeding. Rhinoscopic examination and imaging studies showed a mass occupying the right nasal cavity without bone destruction. The tumor was removed successfully by transnasal endoscopic excision. The pathological examination with immunohistochemistry confirmed the diagnosis of glomangiopericytoma. Histological characteristics, therapeutic principles and prognosis of this tumor are discussed in this article.
