Glomangiopericytoma: A Rare Sinonasal Neoplasm

Abstract

Glomangiopericytoma is a rare neoplasm of the nasal and paranasal sinuses comprising less than 1% of all tumors of the said region. We report of a 59-year-old hypertensive male who presented with epistaxis. CT scan findings showed a mass in the right nasal cavity with extension into the ethmoid and sphenoid sinuses. Histopathologic diagnosis was glomangiopericytoma confirmed with immunohistochemistry studies. Prognosis is favorable with complete resection of tumor and long-term monitoring.
