<p>Antrochoanal polyps are benign mucosal lesions emerging from the maxillary sinus. The primary symptoms are nasal obstruction and rhinorrhea. Endoscopic and radiological appearance of the disease is typical. These polyps are usually presented unilaterally, although bilateral presentation is also possible. In this paper, we report a case of atypically giant antrochoanal polyp in a 13-year-old child. The patient's primary complaint was a sensation of lump in her throat. The examination revealed a mass behind soft palate. The excised polyp had the histological characteristic of an angiomatous antrochoanal polyp. Because of the unusual dimension, the combined transoral and endonasal endoscopic approach was performed for complete polyp excision. We discussed the clinical, histopathological and immunohistochemical characteristics of choanal polyps in comparison to inflammatory nasal polyps, and the applicable surgical techniques for treatment of these polyps.</p>
