A case of middle ear Papilloma originating from the Eustachian tube

Papilloma in middle ear is extremely rare in otolaryngology field. Inverted papilloma involving the middle ear has a high recurrence rate and a possibility of malignant change. As these tumors seldom involve the middle ear, there are no estimates on the incidence of these lesions in this particular site and only a few reports in the literature. We experienced a case of papilloma of the middle ear originating from the Eustachian tube accompanied by cholesteatoma. Thirty-year-old woman visited our clinic and was treated with open canal wall tympanomastoidectomy, There was a pink papillomatous mass located at tympanic orifice of the Eustachian tube. That mass was identified as papilloma. There was no recurrence of cholesteatoma and papilloma 2 years after the operation. This paper aims to report a case of primary middle ear papilloma in a patient with no account of previous nasal disease with literature.
