영문 초록

Primary neoplasms of the external ear canal are rare, and 5% of these tumors are of glandular origin. Ceruminal glands are modified sweat glands, confined to the skin lining of the cartilaginous part of the external auditory canal. Those may give rise to tumors such as ceruminous adenoma, pleomorphic adenoma, ceruminous adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma. An alternative theory holds that pleomorphic adenomas may well arise from ectopic salivary tissue present in the external ear canal. These tumors are very rare and usually have a benign course but there are some controversies on the therapeutic principle of pleomorphic adenoma in external ear canal. A case of pleomorphic adenoma of ceruminous glands is presented along with literature review.
