Abstract
BACKGROUND: Primary inverted papillomas of the middle ear are extremely rare tumors, with only few cases published in the literature. They have a characteristic epithelium surface inversion to the inside of the stroma. Inverted papillomas are benign lesions but have a high propensity of recurrence, local aggressiveness, and association with malignancy.
METHODS: We present a patient with an inverted papilloma originating in the middle ear producing chronic otorrhea and facial nerve palsy treated with a subtotal petrosectomy.
RESULTS: During the follow-up, the patient developed an intracranial invasion of the tumor causing his death.
CONCLUSION: Primary inverted papillomas of the middle ear can have an extremely aggressive behavior despite their benign characteristics; therefore, an aggressive treatment must be performed in order to minimize the possibility of recurrence. © 2015 Wiley Periodicals, Inc. Head Neck, 2015.
