Introduction: Inverted papilloma is a benign tumor that generally arises from the lateral wall of the nasal cavity and mostly grows on the middle meatus.The incidence is rarely found in the ear, throat, nose, throat, head and neck, which is around 0.5% -4% of all nasal and paranasal sinus tumors.The etiology of inverted papilloma remains unknown.Clinical features of inverted papilloma are unilateral nasal obstruction, rhinorrhea, epistaxis, anosmia, tinnitus and some other symptoms.The diagnostic examination are histopathological examinations, CT scans and magnetic resonance imaging (MRI). Histopathology is the gold standard in diagnosing of inverted papilloma.Management of inverted papilloma is carried out with surgical approach including lateral rhinotomy, maxillectomy, degloving, and non-invasive surgery via endoscopy depending to the krouse classification.

Case description: A 44-year-old female patient diagnosed with inverted papilloma was reported.The patient complained of progressive right nasal obstruction appeared two years ago which turned into total obstruction and rhinorrhea in the last 6 months.A biopsy was done with the result of inverted papilloma. CT scan of the paranasal sinuses showed a mass filling the right nasal cavity, right maxillary sinus and right ethmoid sinus. Patientwas diagnosed with sinonasal inverted papilloma with Krouse 2 classification based on clinical examination, radiological findings and preoperative endoscopy. The patient was treated with sinonasal inverted papilloma extirpation via endoscopic approach.

Conclusion: Inverted papilloma is a benign tumor of the nasal and paranasal sinuses in which biopsy is the gold standard for diagnostic test while the main treatment is done by surgical approach depending on the krouse classification.
