[Adenoma of the middle ear].
We report a case of middle ear adenoma, a rare epithelial tumour composed of adenomatous and neuroendocrine cells. These tumours have been designated by many different names, leading to controversy regarding their histogenesis and classification. The diagnosis was based on light microscopy and immunohistochemistry. A positive immunoreaction was evidenced for antibodies to keratin and chromogranin. The tumour was removed surgically. No additional therapy is recommended in the literature.
