Abstract
|
|
|
|
Middle ear adenoma is a rare benign tumor of the tympanic cavity. The first report of a adenomatous tumor of middle ear was published in 1976 by Hyams. It can have both neuroendocrine and epithelial differentiation. Immunohistochemical techniques have helped clarify that these tumors all share elements of neuroendocrine differentiation. Due to non specific clinical symptom and imaging finding, preop-diagnosis was difficult. And behavior of middle ear adenoma was not predictable. In the past few years, there have been reports on metastasis of middle ear adenomas. In this study, we present a case of middle ear adenoma of a patient complaining non whirling type vertigo, hearing difficulty, which was diagnosed by histopathologic finding.
