Inverted papilloma is a benign tumor of the nasal fossa, in which epithelial cells proliferate in clusters (papilloma) toward the underlying chorion: this particular feature is the origin of the name inverted. The most common clinical presentation is unilateral nasal obstruction with rhinorrhea. Complementary assessment requires MRI of the sinus cavities and biopsy. The procedure is surgical and consists of total tumor removal, which is most often performed by endoscopy. The following case illustrates the clinicoradiological and histological aspects of an inverted papilloma in 55-year-old man.
