Abstract
|
|
|
|
Glomus tumors, also called paragangliomas, originate from nonchromaffin cells. They are slow-growing benign lesions and represent the most common primary neoplasm of the middle ear. It is worth mentioning that the most common symptoms are pulsating tinnitus and hearing loss. Imaging studies (CT and MRI) are necessary for diagnosis. Although most of cases are limited to the middle ear, this article reports a glomus tumor presented with a polypoid mass in the external auditory canal.
