외이도에 반복적으로 재발한 다형선종 1예

Pleomorphic adenoma arises commonly in major salivary gland, but it occurs from external auditory canal in literature. It is well known that incomplete surgery for example, simple enucleation or partial resection, cause high recurrence rate of tumor. Surgery requires wide excision with adequate normal margin surrounding the tumor. We experienced a case of pleomorphic adenoma of the external auditory canal, which recurred four times after local excision with laser. We report the case with a brief review of related literature.
