Middle turbinate angiofibroma in an adolescent boy

Mohamed Faizal Hassan et al. BMJ Case Rep. .

Abstract

Bleeding nasal mass in adolescent boys has customarily been attributed to Juvenile nasopharyngeal angiofibroma. However, little is known regarding the extranasopharyngeal origin of angiofibroma, as highlighted in this case report of a 15-year-old boy who presented with recurrent epistaxis and nasal obstruction. On constructing a working diagnosis of nasal haemangioma, the patient was taken up for endoscopic excision under general anaesthesia. Intraoperative endoscopic findings and histopathological examination revealed the diagnosis of middle turbinate angiofibroma, which is an extremely rare extranasopharyngeal angiofibroma. Consequently, this represents the third described case of a juvenile angiofibroma arising from the middle turbinate.

Keywords: hemangioma; otolaryngology / ENT; pathology.
