A Case of Cerumnious Adenoma with Deformity of Cartilage and Bone of the External Auditory Canal

Ceruminous adenoma is a well-circumscribed tumor that originates from apocrine glands located in the external auditory canal (EAC).It is a rare disease that accounts for 5.7% of all EAC and auricular tumors.It usually presents as slow-growing tumor accompanying several ear symptoms; mass, fullness, hearing loss, pruritus and otorrhea.If the detection of the tumor is delayed, the tumor can obstruct the EAC completely and its further growth may lead to deformation of surrounding structures such as the cartilaginous or bony portion of EAC.The wide local excision is the treatment of choice for benign ceruminous gland tumors and thorough histopathologic review is essential in that there is possibility of recurrence and malignant transformation.Herein, we present a case of ceruminous adenoma with cartilage and bony deformation in the EAC with a literature review.
