Ceruminoma: A benign adenoma arising from the ceruminous glands of the external auditory canal.
There are many types of benign tumors that can appear in the ear canal- such tumors include sebaceous cysts, osteomas and exostosis. These benign tumors in the ear canal can cause hearing loss due to buildup of earwax.
Cerumen glands are located in the outer or cartilaginous portion of the external
auditory canal and are modified apocrine glands. These modified sweat glands are similar to the apocrine sweat glands of the axilla. These tumors do not spread to other areas but they are destructive to the ear canal. Adenoid cystic carcinoma is a rare variety of Ceruminoma.
The most effective treatment is surgical removal of the tumor and the surrounding tissue; the specimen should be submitted for histopathology.
