Introduction and importance: Glomangiopericytoma (GPC) is a rare tumor in nasal cavity and paranasal sinuses (PNS) emerging from pericytes surrounding the capillaries and accounts for less than 0.5% of all sinonasal neoplasms. This neoplasm has low malignant potential and an excellent prognosis. Case presentation: We report a case of a 64-year-old woman who presented with nasal obstruction, nasal discharge, loss of sense of smell, headache, and one episode of nasal bleeding. Rhinoscopy revealed polypoid tissue in the left nasal cavity. Probing revealed tissue bleed on touch. A contrast-enhanced computed tomography (CECT) scan of the nose and PNS reported a well-defined soft tissue density lesion of size 30 × 18 × 40 mm in the left anterior nasal cavity showing mild peripheral heterogeneous contrast enhancement. Preoperative biopsy was suggestive of lobular capillary hemangioma. Complete surgical excision was done under general anesthesia, using external approach. Postoperative histopathology report suggested GPC. Discussion: Glomangiopericytoma has appearance similar to inflammatory nasal polyps, therefore can create confusion for clinicians. Histopathological tissue examination is the gold standard for definitive diagnosis. The preferred management option includes complete surgical excision having 5-year survival rate of 88%. Conclusion: Glomangiopericytoma is a rare sinonasal neoplasm with borderline or low malignant potential. As it is a rare tumor having ambiguous clinical and radiological signs, a high index of suspicion is required for the diagnosis of GPC. Complete surgical excision is the mainstay of treatment. Rare case reports are required to generate adequate data pool and making guidelines for diagnosis and treatment outcomes.
