Angiofibroma is a benign vascular lesion that typically affects young males within the age range from 9 to 18 years. The epicentre of the lesion is located at the level of the pterygopalatine fossa, but extension to the skull base is observed in 20–25% of patients. Angiofibroma commonly appears at nasal endoscopy as a hypervascularised polypoid lesion with well-defined margins and no presence of necrotic areas. Hormonal aetiology may play a role in its development. Histologically, angiofibroma is made by numerous thin-walled vessels of varying shapes and sizes embedded in a collagenous tissue.
