Idiopathic, Infectious and Reactive Lesions of the Ear and Temporal Bone

Abstract

A number of infectious, inflammatory and idiopathic lesions develop within otologic tissues that may share similar clinical and/or microscopic features. This review first provides a working classification for otitis externa, and then otitis media and includes two recently described entities, eosinophilic otitis media and otitis media with ANCA-associated vasculitis. Next, the microscopic findings of a spectrum of otopathologic conditions are described, including post-inflammatory conditions such as tympanosclerosis and aural polyps, an overview of animate aural foreign body as well as iatrogenic aural foreign body reactions. Finally, a review of fungal disease affecting the ear with a brief synopsis of Candida auris, a recently described and virulent organism, is presented.
