Adenoid Cystic Carcinoma of the External Auditory: A Rare Case Presentation

Objective: To describe a case of adenoid cystic carcinoma of the external auditory canal without bone lysis.

Presentation of the Case: A 60-year-old female patient presented to our department with a stenotic mass in the external auditory canal that was progressively increasing in size and evolving for 5 years of incidental finding. The imaging, as well as the clinical and biological picture evoked a tumor of the external acoustic meatus, at the anapath a grade 2 adenoid cystic carcinoma was diagnosed. The treatment was surgical and the patient benefited from excision of the mass in one piece of the external auditory canal. A potent irradiation terminated the treatment. The suites were simple. The follow-up is 2 months without recurrence.

Findings: Adenoid cystic carcinoma of the external acoustic meatus is a rare malignant tumor whose diagnosis is often late Due to their initial symptomatology similar to that of other benign conditions of the ear which makes their prognosis pejorative whose cure depends essentially on local control. Its metastatic potential justifies aggressive treatment.
