Sebaceous neoplasms of the external ear canal are extremely rare. Only two cases of sebaceous neoplasms have been reported in the English literature, a sebaceous carcinoma and a sebaceous adenoma. We report a case of sebaceoma of the external ear canal. To the best of our knowledge, sebaceoma of the auditory canal has not been reported previously. We highlight the differential diagnosis, particularly sebaceous carcinoma and basal cell carcinoma with sebaceous differentiation. Awareness of the possible occurrence of sebaceoma in the auditory canal may prevent the diagnostic pitfall of misidentifying this tumor.
