Unusual Tumors of the Ear Canal

  • Paul W. Gidley


While squamous cell carcinoma and basal cell carcinoma account for the vast majority of ear canal tumors, there remain a number of rare and unusual tumor types that occur within the ear canal. This chapter describes the anatomy of the ear canal, especially with respect to the ceruminous glands, which are the source of these unusual tumors. Benign and malignant tumors are described. Adenocarcinoma and adenoid cystic carcinoma are discussed due to their common origin from cerumen glands in the external ear canal.
