Abstract

Angiomatous nasal polyps are a rarely reported subtype of inflammatory sinonasal polyps that are characterized by extensive vascular proliferation and ectasia. The blood vessels present in these sinonasal polyps may be subjected to compromise at certain areas within the nasal cavity, leading to venous stasis, thrombosis and infarction. Recently, we experienced a case of angiomatous nasal polyp that caused significant diagnostic difficulty at the time of her presentation in a 12-year-old girl. Although entirely benign, angiomatous nasal polyps may simulate neoplastic process, thus awareness of their existence is of considerable importance. Especially, differential diagnosis between angiomatous polyp and angiofibroma is important for evaluation and treatment. In the present paper, the clinical, radiological and pathological features of angiomatous nasal polyps is also discussed.
