Adenoid cystic carcinoma of external auditory canal: A case report

Primary malignancies of the external auditory canal (EAC) are extremely rare with more than 80% being squamous cell carcinomas and adenoid cystic carcinoma (ACC) accounting for approximately 5%. These tumours are associated with a high risk of recurrence and significant morbidities from surgical management and adjuvant radiotherapy. Therefore, we present a case of young female with right EAC mass diagnosed as cylindroma and confirmed postoperatively to be ACC of the EAC which is a rare case in the literature.
