Primary Pleomorphic Adenoma of External Auditory Canal.

Primary pleomorhic adenoma (Chondroid syringoma) arising from the external auditory canal is very rare and because of the unremarkable clinical presentation, the diagnosis is often made after microscopic examination. We reviewed the worldwide literature and found that only forty one cases have been previously reported. In this report, we describe one such unusual case. The treatment of choice is wide local excision without esthetic or functional disruption of surrounding structures, followed by careful long-term post-operative observation of the clinical course.
