Abstract

Primary external auditory canal malignancies are very rare; in which, adenoid cystic carcinoma is extremely rare tumour accounting for approximately 5%. Majority of the patients presents with unilateral severe or dull aching constant ear pain of prolonged duration, reduced hearing and mass in the External Ear. These tumours are treated with aggressive surgical excision and adjuvant radiotherapy. Despite this, the overall prognosis is poor due to recurrences and distant metastasis. We report a rare case of adenoid cystic carcinoma in a 36-year-old female, who presented with right ear pain for the last one year. She was treated with wide local excision of the mass followed by adjuvant radiotherapy.
