Uncommonly sited rare tumour causing nasal obstruction.

​: ​The study aims to discuss a case of an uncommonly sited rare tumour causing nasal obstruction and a literature review of angioleiomyomas in the nose. A 64-year-old woman presented with blockage of the right nostril, associated with a visible swelling on the undersurface of the alar cartilage, in the lateral wall of the nasal cavity. Anterior rhinoscopy highlighted a 1 cm cystic lesion, with areas of firmness, present at the mucocutaneous junction with a broad base. It was not attached to the underlying cartilage. There was no ulceration or bleeding on palpation. Nasal endoscopy did not show any extension further and the rest of the nasal cavity was clear. Endonasal resection of the tumour using a two-handed technique. This paper highlights not only the importance of considering angioleiomyomas within a differential diagnosis of nasal obstructions but also the uncommon site. ​. © BMJ Publishing Group Limited 2020.
