Description
Summary:Angiectatic nasal polyp (ANP) is a rare entity of inflammatory sinonasal polyps, constituting only 4–5% of all nasal polyps. Clinically, this rare entity closely simulates hemangiomas, inverted papilloma and epithelial or mesenchymal tumors. Differentiation is very important as their lines of management are significantly different. Extensive vascular proliferation, atypical stromal cells and amorphous eosinophilic material on histopathology are typical of these polyps. A 11-year-old-girl presented to us with an extensive ANP masquerading as a malignant nasal mass, both clinically and radiologically. Patient underwent complete excision with functional endoscopic sinus surgery and is asymptomatic on regular follow-up. Prognosis is good and recurrence is very rare, if treated correctly. Only a few studies have been done on this topic, the literature is scant and awareness of this pathology is important.
