Rare and Unusual Localization of Adenoid Cystic Carcinoma : A Case Report

Introduction: Adenoid cystic carcinoma (ACC) of the external auditory canal (EAC) is an extremely rare tumor. Case Report: This is about a 62-year-old female Moroccan patient with no particular medical history who consulted for a mass in the right external auditory canal revolving for 1 year. The biopsy showed an ACC of the right external auditory canal. Discussion and Conclusion: The external auditory localization of ACC is rare and unusual, making diagnosis and treatment difficult given the low incidence of the disease. A pathological examination must be performed to establish a positive diagnosis and assess the margins. For patients with uncertain negative margins, postoperative radiotherapy and chemotherapy may be considered to reduce recurrence and improve survival.
