Abstract Myopericytoma is a mesenchymal tumour that shares characteristics with other soft tissue tumours including glomus tumours and myofibromas. These pericytic tumours show characteristic perivascular growth patterns (Sbaraglia M, Bellan E, Dei Tos AP. The 2020 WHO classification of soft tissue tumours: news and perspectives. Pathologica 2021;113:70–84. https://doi.org/10.32074/1591-951X-213). Myopericytoma differentiates itself as it tends to have a spindle shape histologically, rather than an epithelioid shape as with the glomus variety. Myopericytoma rarely demonstrate malignant behaviour. A 67-year-old male presented to our clinic with complaints of increased frequency of right sided epistaxis for several months. The epistaxis episodes were controlled with oxymetazoline spray and manual pressure to the nasal tip. Office nasal endoscopy revealed a mass emanating from the anterior end of the right inferior turbinate. Complete excision was performed endoscopically. Histopathological analysis revealed myopericytoma, a rare tumour typically arising from the epithelium or submucosa. This case underscores the need for otolaryngologists to consider perivascular tumours in the differential diagnosis of intranasal masses as complete excision is recommended to avoid recurrence.
