Abstract
A fibroepithelial polyp is a mucosal polypoid lesion comprising connective tissue and
covered by benign local epithelium. They can occur on any area of the body with an epithelial surface. We report a fibroepithelial polyp of the right maxillary sinus as the first case of fibroepithelial polyp of the paranasal sinuses which presented with unilateral nasal obstruction. The patient
completely recovered after surgical treatment. The differential diagnosis of unilateral sinonasal
growing masses in elderly patients includes various benign and malignant diseases and fibroepithelial polyp should be considered as a possible diagnosis. Nasal fibroepithelial polyps are treated
surgically and have a favorable prognosis.
