External auditory canal adenoid cystic carcinoma (EAC) is rare and is associated with nonspecific clinical manifestations such as early ear pain. We report a patient with advanced lung metastases from adenoid cystic carcinoma (ACC) of the EAC, which is difficult to diagnose. Under general anesthesia, lengthened right temporal bone resection, parotidectomy, facial nerve resection, cervical lymph node dissection (I-III), partial mandibular resection, tumor resection in the inferior temporal fossa and lateral femoral flap repair were performed, followed by regular radiotherapy and chemotherapy. During 2 years of postsurgical follow-up, there was no recurrence. The combination of early detection, resection, postoperative radiotherapy, and chemotherapy can result in a good therapeutic effect.
外耳道腺样囊性癌（EAC）较为罕见，伴有耳痛等非特异性临床表现。我们报告了1例外耳道腺样囊性癌（ACC）发生肺转移且病情已进展至晚期的患者，该病例诊断困难。在全身麻醉下，实施了右侧颞骨延长切除术、腮腺切除术、面神经切除术、颈部淋巴结清扫术（I-III区）、部分下颌骨切除术、颞下窝肿瘤切除术及股外侧皮瓣修复术，随后进行了规律的放疗和化疗。术后2年随访期间未出现复发。早期发现、手术切除、术后放疗及化疗相结合可取得良好的治疗效果。
