Abstract

|
Glomangiopericytoma, a new term referring to the sinonasal type hemangiopericytoma, is a rare sinonasal tumor arising from modified perivascular glomus-like myoid cells. It is a borderline, low grade malignancy tumor, which has good prognosis following a complete surgical resection. Recently, we experienced a case of a glomangiopericytoma in a 68-year-old woman who presented with epistaxis and unilateral nasal obstruction. Endoscopic examinations revealed polypoid mass with bleeding tendency in the left middle meatus. The tumor was located mainly in the left ethmoid sinus and we removed it successfully by endoscopic approach. Histological examination and immunohistochemistry confirmed the diagnosis of glomangiopericytoma. We present the clinical and histological characteristics, therapeutic principles, and prognosis of this rare disease entity with a literature review.
