Intracranial Invasion of a Ceruminous Gland Tumor: A Follow-Up of 12 Years

Abstract
A man 44 years of age had a ceruminous gland tumor originating in the external auditory canal. A follow-up of 12 years showed the deliberate invasive nature of the tumor, which invaded the petrous bone and actually penetrated intracranially. The tumor was repeatedly treated by surgical excision and irradiation. At present, the patient has been in good condition for two successive years. As far as we are aware, only two comparable case histories have been reported in the literature. The present case may illustrate the fact that a tumor resembling the normal ceruminous gland should be considered as potentially malignant. Consequently, the term "ceruminoma" should be avoided.
