Ceruminoma is a collective term applied to tumors arising from the modified apocrine (ceruminous) glands of the external auditory canal. Four distinctive histopathologic patterns are recognized: adenoma, pleomorphic adenoma, adenoid cystic carcinoma, and adenocarcinoma. We report a case of pleomorphic adenoma. It manifested as a soft mass covered with epithelium, filling the right external auditory canal. Wide local excision was the treatment, but local recurrence appeared four years later.
