Primary Inverted Papilloma of Middle Ear and Mastoid: A Rare Case Report.

Inverted papilloma or Schneiderian papilloma arising primarily from middle ear and mastoid is a very rare entity. It is a benign and locally aggressive condition, with increased risk of recurrence and malignant transformation. Surgery is the primary treatment. Radiation therapy should be considered in case of malignant transformation, recurrent or inoperable disease. Here we are reporting a case of recurrent inverted papilloma with dysplastic changes arising from mastoid cavity in a 60-year-old male. The patient was treated with surgery followed by radiotherapy.
