Thymoma is the most common neoplasm in the anterior mediastinum. This report presents an extremely rare case of a type A thymoma with Masaoka's stage IV b due to lymph node metastasis. In 1997, a 59-year-old man underwent complete resection of a stage IV b type A thymoma with postoperative radiotherapy to the mediastinum. In 2006, small nodules were detected in the anterior mediastinum and above the right diaphragm and tumor resection was performed. The two lesions were both histologically diagnosed as recurrences of the type A thymoma. There has been no evidence of recurrence 15 months after the second surgery.
胸腺瘤是前纵隔最常见的肿瘤。本报告介绍了1例极为罕见的A型胸腺瘤，因淋巴结转移处于Masaoka IVb期。1997年，一名59岁男性接受了IVb期A型胸腺瘤的完整切除，并于术后接受了纵隔放疗。2006年，在前纵隔及右膈上方发现小结节，遂行肿瘤切除术。这两处病变经组织学诊断均为A型胸腺瘤复发。第二次手术后15个月尚无复发迹象。
