A Case of Inverted Papilloma Originating from Posterior Nasal Septum

ABSTRACT

Inverted papilloma is an uncommon benign nasal tumor which usually occurs on the lateral nasal wall. An inverted papilloma originating from the medial nasal cavity, especially the nasal septum, is considered very rare. A 47-year-old male was referred with a 1-month history of snoring. On endoscopic examination, a nasal mass was observed in the left posterior septum. The mass filled the left nasal cavity and extended choanae and nasopharynx. The histopathologic examination of the nasal mass showed inverted papilloma, which was completely removed by endoscopic surgery. Herein, the authors report a case of inverted papilloma originating from the posterior nasal septum as well as a review of literature.
