A Case of Middle Ear Adenoma

Abstract

Middle ear adenomas and adenocarcinomas are both rare lesions and the clinical and histopathological distinction between these lesions is difficult.
We report a 26-year-old man with a middle ear adenoma that originated from the right middle ear mucosa. The mass was found in the posterior tympanum. It surrounded intact ossicles and extended to the additus and mastoid antrum. The patient underwent tympanoplasty with mastoidectomy.
In this case, we diagnosed this lesion as middle ear adenoma from the absence of bone destruction, confinement to the middle ear cleft and lack of metastasis as Hyams & Michaels noted in 1976. The postoperative course has been uneventful for nearly 7 months.
The literature indicates that of there is no invasion, most of these tumors are benign and the prognosis is good, but a few recurrences are reported, so the careful follow-up is mandatory.
