Abstract
Ceruminous adenoma is described as a glandular neoplasm of ceruminous glands. It is seen for less than one percent of all external ear tumours. Ceruminous adenoma cases were reported to have recurrence and residual tumour, however there was no malignant transformation known in ceruminous adenoma up to this date. Here, we report a young adult woman with two years history of progressive reduced hearing and tinnitus of the right ear. She was proven to have right moderate conductive hearing loss with pure tone audiometry. There was a cystic mass with serous content arising from the posterior wall of the right ear canal. We proceeded with wide local excision of the mass via trans-canal approach. Ceruminous adenoma was confirmed with histopathology and immunohistochemistry of CK7 staining. The hearing impairment was resolved completely post excision and there was no recurrence of the tumour on one year follow-up. We concluded wide local excision with appropriate margin of the mass is adequate to prevent recurrence in ceruminous adenoma cases.
