External auditory canal neoplasms comprise less than 1 percent of all head and neck tumors. They are ceruminous gland-originated tumors in 2.4 percent of cases. In the past, all these tumors were called ceruminomas. In 1972 Wetli et al. classified these neoplasms into four groups: ceruminous adenomas, ceruminous carcinoma, adenoid cystic carcinomas, and pleomorphic adenomas. Ceruminous adenocarcinoma is very rare. It has no specific symptoms, therefore, an appropriate, quick diagnosis is difficult; it is very aggressive. Treatment should be based on tumor resection and followed by radiotherapy. We presented a case of a 56-year-old female with a lump in the external ear canal, who underwent diagnostic surgical excision of the tumor in the external auditory canal. The postoperative histopathological diagnosis was ceruminous adenocarcinoma (complete excision) and the patient received radiation therapy. Follow-up CT and MR – performed one year after surgery - showed a possible local recurrence of pathology. The patient underwent maximal surgical resection with subtotal petrosectomy but postoperative histological examination showed no malignant cells. Treatment of external auditory canal neoplasms should be based on radical surgical resection. Diagnostic imaging is very important in follow up examination but it can have limited value in terms of its specificity.
