Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus. Nasal obstruction and rhinorrhea are their main symptoms. Their endoscopical and radiological appearance makes them relatively easy to diagnose. These polyps are usually presented unilaterally, although bilateral presentation is also possible. We described two cases of atypically giant antrochoanal polyps: in a 15-year-old child and in a 38-year-old man. In both cases, the diagnosis was done by nasal endoscopy and computed tomography (CT) of the paranasal sinuses and supported by histopathological analysis. In the first patient, the excised polyp had the histological characteristic of an angiomatous antrochoanal polyp. Because of their 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.

“…On the other hand, Sayed and Abu-Dief [9] suggest that angiomatous polyp is a distinct type of nasal polyp and not a derivate of the ordinary CP. They found that only angiomatous variant of nasal polyps presents with epistaxis.…”

“…The stroma of angiomatous polyps have large numbers of dilated capillary spaces and numerous large hemosiderin-laden macrophages suggesting the presence of two parallel processes: blood extravasation and stromal tissue reparation. [6,9] Clinically and radiologically, angiomatous CPs may be confused with vascular neoplasms, including nasopharyngeal angiofibroma. The early identification of cases similar to angiofibroma is of crucial importance.…”

AbstractChoanal polyps (CPs) can be defined as histologically benign, solitary, soft tissue lesions extending towards the junction between the nasal cavity and the nasopharynx through the choana. They usually originate from the maxillary sinus. In this report, we present an unusual case of a giant angiomatous CP arising from the inferior part of the middle turbinate that completely filled the nasopharynx. A 24-year-old man presented with five-year history of left-sided nasal obstruction, nasal discharge and mildto-moderate epistaxis. The diagnosis was supported by contrastenhanced computed tomography scan of the paranasal sinuses with angiography and confirmed by histopathological examination. The lesion was removed by combined endoscopic and transoral approach. In addition, we discuss the pathogenesis, clinical, radiological and pathological characteristics of angiomatous CPs, and their differential diagnosis.

“…Other symptoms are loss of smell sensation, epistaxis, 11 exophthalmoses, proptosis and visual disturbances 6 .On anterior rhinoscopy, they appear as a smooth, bluish gray/reddish polypoidal mass with shiny surface. Angiomatous nasal polyp may exceptionally cause extensive bone erosion and remodeling.…”
