Extranasopharyngeal angiofibroma originating in the inferior turbinate: A distinct clinical entity at an unusual site

Abstract

Introduction: The extranasopharyngeal angio fibroma is histologically similar to juvenile nasopharyngeal angiofibroma, differing fromthe latter in clinical and epidemiologic characteristics. Objectives: We present a case of extranasopharyngeal angio fibroma originating in the inferior turbinate. Resumed: Report The patient was a girl, 8 years and 6 months of age, who had constant bilateral nasal obstruction and recurrent epistaxis for 6 months, worse on the right side, with hyposmia and snoring. Nasal endoscopy showed a reddish lesion, smooth, friable, and nonulcerated. Computed tomography showed a lesion with soft tissue density in the right nasal cavity. We used an endoscopic approach and found the lesion inserted in the right inferior turbinate. We did a subperiosteal dissection and excision with a partial turbinectomy with a resection margin of 0.5 cm. Histopathology reported it to be an extranasopharyngeal angiofibroma. Conclusion: Although rare, extranasopharyngeal angiofibroma should be considered in the diagnosis of vascular tumors of the head and neck.
