“…On computed tomography antrochoanal polyps are seen between the middle turbinate and lateral wall of the nasal cavity, while the choanal polyp arising from concha as in our case occupies the space between the middle turbinate and septum. 1 Thus, in choanal polyps middle meatus appears free. Moreover, ipsilateral maxillary sinus is opaque in antrochoanal polyps.…”

“…Also, inverted papilloma should be kept as a possibility in cases of unusual site of choanal polyp origin. 1 The other differentials for unilateral polyp are blob of mucus which disappears on blowing nose or suction, hypertrophied middle turbinate has pink appearance and hard feel and angiofibroma gives history of profuse recurrent epistaxis and is firm in consistency.…”

Choanal polyp is the term used for benign, solitary soft tissue mass which extend toward the junction of nasal cavity and nasopharynx, i.e. choana. We report a rare case of choanal polyp arising from the middle turbinate and its successful treatment by endoscopic surgery. The complete resection of choanal polyp at the site of origin using an endoscope is usually sufficient and carries good prognosis without recurrence.

“…Intranasal soft-tissue lesions which are seen in pediatric population include nasal polyps, antrochoanal polyps, angiofibroma, fibrous histiocytomas, meningiomas, neurofibromas, hemangiomas, pyogenic granulomas, glioma, meningoencephaloceles and rarely rabdomyosarcomas [1,3,4,6,[12][13][14]. Table 1 shows the differential diagnosis of intranasal soft tissue lesions (Table 1) [1,15,16].…”

“…If an intranasal soft tissue lesion with the total maxillary antrum opacification on the lesion side and enlarged ostium was detected on CT, IP or antrochoanal polyp can be the two most logical diagnoses. In general, the age of the patients may be a factor to differentiate these two entities since IP occurs more commonly in patients over 40 years whereas antrochoanal polyps mostly in children and young adults [8,12]. MRI and CT may not differentiate coincident malignancies from IP [8].…”

Antrochoanal polyp (ACP) is a soft tissue mass originating from the maxillary antrum, emerging from the ostium and extending to the choana through the nasal cavity. Our aim was to investigate the light microscopic and ultrastructural features of ACP and to compare these with nasal polyps originating from the middle meatus (MMP). Seven ACP and seven MMP specimens were evaluated by transmission electron microscopy (TEM) and light microscopy. TEM examination showed epithelial cells with intact cilia covering both polyps. In some MMP cases, degeneration of the epithelium associated with some cilia loss was noted. Goblet cell hyperplasia was more prominent in MMP cases. Degeneration and partial destruction of the endothelial cells of the blood vessels were common findings in ACP cases; however, in the MMP group, endothelial cells were mostly intact with a few aggregates of ribosomes, and intact cell junctions were noted. Light microscopic examination revealed that inflammatory cells in the ACP group were numerous. However, eosinophils were predominant in MMP cases. Squamous metaplasia of the surface epithelium was detected in five ACP cases, but in none of the MMP cases. Basement membrane thickening was detected in two cases of the ACP and in four cases of the MMP group. There was a statistically significant difference between the two groups for inflammatory cells, eosinophilic cell infiltration, squamous cell metaplasia, endothelial cell destruction and goblet cell metaplasia. In conclusion, the low number of eosinophils, the high number of other inflammatory cells, the normal appearing basement membrane and intact and normal surface epithelium may reveal that the etiology of ACP might arise from chronic inflammatory processes rather than allergy. The destruction of the endothelium may be considered as a further sign of chronic inflammation.
