Unveiling a Rarity: A Case Report on Glomangiopericytoma in the nasal cavity

Abstract

Sino-nasal glomangiopericytoma is a rare benign tumour comprising only about 0.5% of all sino-nasal tumours. Presenting as a bleeding nasal mass, it is among the myriad of differential diagnoses for the same. Clinical characterisation of mass becomes difficult; hence, histopathology and immunohistocytochemistry play an essential role in clenching the diagnosis. Optimal treatment includes complete tumour excision with endoscopic or open approaches with or without preoperative embolization and a long post-operative follow-up period. Here we report such a case treated with endoscopic approach.
