A Case of Pleomorphic Adenoma of the External Auditory Canal / 대한이비인후과학회지

ABSTRACT

Pleomorphic adenomas mostly occur in major salivary glands. Pleomorphic adenomas arising in the external auditory canal are very rare. The clinical features and natural history of patients with this tumor are obscure. The patients with pleomorphic adenoma of the external auditory canal mostly complain of painless lump, otorrhea, ear fullness and hearing loss. Treatment of choice is a wide excision of tumor to prevent local recurrence. We experienced a case of pleomorphic adenoma in the external auditory canal causing ear fullness and mild otalgia which was treated by local excision via endaural approach. The patient has been free of disease for about 14 months after the treatment. We report the case with a review of literatures.
