Glomangiopericytoma (GPC) is a rare benign sinonasal tumor originating from Zimmerman's Pericytes surrounding capillaries and accounting for less than 0.05% of all sinonasal tumors. Glomangiopericytoma has low malignant potential (5–10%) and is mostly diagnosed in the 6th or 7th decade of age with slight female preponderance. We presented here a case series of 5 patients with sinonasal GPC. This research was conducted at a tertiary healthcare centre in North India. In our case series, all the patients were evaluated and underwent endoscopic surgical resection. All patients underwent digital subtraction angiography (DSA) and preoperative embolization. The coblation technique used for haemostasis proved very effective and time-saving. All patients exhibited cytoplasmic SMA positivity (a marker of GPC) and CD34 negativity, while one patient exhibited a high Ki-67 index (> 10%), which is a predictor of aggressive tumor behavior. None of the patients showed any recurrence in follow-up. We recommend performing complete endoscopic surgical excision to prevent recurrence. The use of DSA, preoperative embolization, and intraoperative use of the coblation technique provides a cleaner surgical field and reduced operating time. [ABSTRACT FROM AUTHOR]
