Abstract

An adenoid cystic carcinoma (AdCC) of the ceruminous glands is very rare; its diagnosis is most often challenging, and simple biopsies may be misleading. Our paper describes a case of a circumferential mass of the left ear canal that was initially reported as a basal cell carcinoma on biopsies in the clinic and on frozen sections intraoperatively. The final pathology was an AdCC of the ceruminous glands of the external auditory canal. Our case reflects the difficulty in the diagnosis of an AdCC of the ceruminous gland and the importance of keeping broad differential diagnoses in mind when counseling patients with masses in the ear canals until final pathology is obtained.
