Numerous acronyms: Mixed epithelial and neuroendocrine tumor (MENET), neuroendocrine adenoma of middle ear (NAME), middle ear adenoma with neuroendocrine differentiation (MEA-ND), Middle ear adenomatous tumors (MEAT)
Definitions
Very rare, benign tumor arising from mucosal cells of ME having variable mixed epithelial & neuroendocrine differentiation
Not choristoma or ceruminoma
Salivary choristoma = normal salivary tissue in abnormal location, not adenoma
Ceruminoma = benign glandular tumor (adenoma) arising from ceruminous glands
Indolent tumor of glandular origin
