In general, tumors of the external auditory canal (EAC) are quite uncommon, and glandular tumors comprise only a minority of these tumors. Tumors of the ceruminous gland are infrequent in the EAC. Ceruminous adenocarcinoma is a malignant subtype of ceruminous gland neoplasm,1 which is an exceedingly rare malignant tumor of the EAC. The true incidence and biological behavior of these tumors is still obscure, owing not only to the rarity of these tumors but also to ambiguous tumor nomenclature. The dearth of knowledge about this disease entity leads to difficulty in establishing the formulation of definitive treatment plans.
