Objective: To present a rare case of Adenoid Cystic Carcinoma of the external ear canal in a 73-year-old man, including its diagnosis and surgical management.
Methods:
Design: Case Report
Setting: Tertiary Government Training Hospital
Patient: One
Results: A 73-year-old man who consulted due to decreased hearing on the right ear had a 4-year history of gradually enlarging mass occupying the right external auditory canal. Wide en bloc resection of the external auditory canal mass and superficial parotidectomy with facial nerve preservation was performed with final histopathology results of adenoid cystic carcinoma. Follow-up at 2 years has shown no signs or symptoms or recurrence.
Conclusion: Adenoid cystic carcinoma of the external ear canal is a very rare disease that can present similarly to other otologic infections. Early identification of symptoms, performance of necessary imaging, and timely biopsy are key to reducing misdiagnosis and improving the survival rate. Complete resection of the tumor with adequate margins is the recommended treatment due to its high rates for recurrence.
