Primary Pleomorphic Adenoma of the External Auditory Canal-A Case Report and Literature Review

Tumours primarily arising from the external auditory canal are very uncommon and 5% of these originate from the glands present in the skin. Primary Pleomorphic adenomas arising from the External Auditory Canal are extremely rare and are difficult to diagnose preoperatively. They have clinically unremarkable presentation, and are treated by wide local excision with adequate normal margins. These tumours are mostly diagnosed postoperatively by histopathological examination and requires a long term follow up. In this case report we describe one such unusual case of primary Pleomorphic adenoma of the external auditory canal along with the literature review.
