Abstract:
We present the case of a 38-year-old man with an adenoid cystic carcinoma originating from the ceruminous glands of the external ear canal. The patient subsequently presented with a contralateral brain mass that was also diagnosed as adenoid cystic carcinoma. To our knowledge, contralateral metastasis to the brain of a patient with an adenoid cystic carcinoma of the ceruminous glands has not been reported previously. This rare neoplasm should be considered in the differential diagnosis of poorly differentiated carcinomas metastatic to the central nervous system in patients with occult malignant neoplasms.
