Fibroepithelial Polyp Originating from the Nasal Septum.

Fibroepithelial polyp (FEP) is a rare clinical condition of mesodermal origin, covered usually by squamous epithelium, originating most frequently from the skin, genitourinary and lower respiratory tract. Upper airway FEP is a rare lesion found usually in the pharynx and larynx. Only three cases of FEP arising from the nasal mucosa were reported in the world literature, all from the inferior nasal turbinate. In this paper, we describe the first case in the literature of a FEP originating from the nasal septum in a patient suffering from perennial allergic rhinitis. In addition, we discussed the etiology, pathogenesis, histopathological and clinical characteristics of FEPs.
