Choanal polyps are benign solitary soft tissue lesions which originates from the nasal or paranasal sinus mucosa and progress through the natural ostium of the sinus to choana into the nasopharynx. Antrochoanal polyps are most common type. Nasal septum, sphenoid sinus, ethmoid sinus, inferior and middle turbinate, inferior and middle meatus have been reported as ectopic origin of choanal polyp as well. However, choanal polyps originating from uncinate process of nasal cavity has not been reported. Herein, with a review of the literature, we report a rare case of choanal polyps originating from uncinated process of nasal cavity in a 52-year-old woman.
