title: [Middle ear adenoma: a case report].
abstract: Middle ear adenoma (MEA) is a rare neoplasm with benign clinical behavior. The immunohistochemical and ultrastructural studies revealed the mixed, bidirectional mucinous and neuroendocrine character. These tumors have been known by many different names, reflecting the controversies relating to their histogenesis and differentiation. The term middle ear adenoma was proposed by Hyams and Michaels in 1976 and since this time over 100 cases were described in the literature. The most often symptoms of the MEA are the unilateral hearing loss and the tinnitus. MEA should be treated by surgery and very attentive postoperative follow-up. The prognosis of these tumors are good. The histological structure of middle ear adenoma, as well as symptomatology, treatment and clinical behavior are discussed on the basis of the literature. A case of histologically confirmed middle ear adenoma in a 34 year old women is presented.
