BITTENCOURT, Aline Gomes et al. Middle ear adenoma with neuroendocrine differentiation: relate of two cases and literature review. Int. Arch. Otorhinolaryngol. [online]. 2013, vol.17, n.3, pp.340-343. ISSN 1809-9777.

INTRODUCTION: Adenomas with neuroendocrine differentiation are defined as neuroendocrine neoplasms, and they are rarely found in the head and neck. OBJECTIVE: To describe two cases of a middle ear adenoma with neuroendocrine differentiation, with a literature review. CASE REPORT: Patient 1 was a 41-year-old woman who presented with a 3-year history of left aural fullness associated with ipsilateral "hammer beating" tinnitus. Patient 2 was a 41-year-old male who presented with unilateral conductive hearing loss. CONCLUSION: Adenoma with neuroendocrine differentiation of the middle ear is a rare entity, but it should be considered in patients with tinnitus, aural fullness, and a retrotympanic mass and remembered as a diferential diagnosis of tympanic paraganglioma.
