Adenoid Cystic Carcinoma of External Auditory Canal: A Report of One Case

目的：探讨外耳道腺样囊性癌的临床及病理特点，以提高诊断和治疗水平。方法：回顾性分析1例外耳道腺样囊性癌患者自首诊8年来连续的临床表现，病程进展，治疗及随访结果。结果：患者术后随访半年无复发。结论：外耳道腺样囊性癌生长缓慢，可长期带瘤生存但远期预后不佳，首次治疗应该采用扩大根治性手术，术后结合临床病理分期辅以放射治疗以提高治愈率。
Objective: To detect the clinical and pathological features of the adenoid cystic carcinoma of external audi-tory canal, and to improve its diagnosis and treatment level. Method: A retrospective analysis has been performed on patients with ACCEAC by their clinical manifestation, the therapy and follow-up results since 8 years ago as well as the combination with there view of related literature. Result: Patients without recurrence of postoperative follow-up of six months. Conclusion: Adenoid cystic carcinoma of external auditory canal, which is rarely seen in clinic, is not easy to exact diagnosis in early stage. It progresses slowly and tends to invade parotid and even intracranial cavity. It also has the tendency of recurrence and pulmonary metastasis. So, it’s necessary to do both aggressive surgery and postoperative irradiation. The long term follow-up indicates that the tumor has a poor prognosis.
