Abstract


Adenoid cystic carcinoma (ACC) is thought as a tumor usually found in salivary gland and it is hard to find in external auditory canal. ACC has a slow progression feature and few early symptoms so it is not easy to diagno- sis in early stage. ACC is often involved perineural invasion but hardly found in lymph node metastasis. Because of these features, patients with ACC have symptoms such as otalgia, otorrhea and ear canal mass. ACC has 3 dif- ferent histologic patterns and each patterns have different prognosis. The treatment of ACC is nowdays surgery and postoperative radiotherapy. We report a ACC case in ear canal with a review of other literatures.
