Papiloma escamoso de orelha média: relato de um caso e revisão da literatura

Inverted papilloma of middle ear is an extremely rare lesion of the respiratory epithelium that normally occurs in the nasal cavity and paranasal sinuses. So far less than 17 cases were described in literature. A 45-year-old patient was admitted in our Department with hearing loss, otorrhea and pulsing tinnitus on the right ear. The clinical examination showed a granulation tissue on the right eardrum. No tumor formation was seen in the nasal cavity. The MRI showed a tissue formation in the tympanic cavity with an extension in the middle cranial fossa. A mastoidectomy with antrotomy and duraplasty was performed. The histological diagnosis was inverted papilloma of the middle ear. In a second step occurred an eradication of the tumor with a subtotal petrosectomy. The etiology of the inverted papilloma of the middle ear is unknown. Our case is so far the 18nd case described.Our experience has shown that the eradication of the tumor with a subtotal petrosectomy resulted as reasonable procedure. A long-term follow-up is suggested in order to detect possible recurrence or malignant transformation.

Inverted papilloma (IP) with malignant transformation is rarely seen in the middle ear. Up to now, there have been 16 primary middle ear IPs reported in the English literature. Even though it is very rare in the middle ear, this pathology should be kept in mind for the differential diagnosis of middle ear masses. In this case, we report a 77-year-old female who had recurrent IP with malignant transformation and complication.
