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.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivs 3.0 United StatesFibroepithelial polypUnilateral nasal obstructionParanasal sinus tumorSinonasal polypUnilateral sinonasal massArticle272757810.5336/caserep.2018-63870336175
