We report a resected case of thymoma with a solitary pulmonary metastasis. A 63-year-old woman had pointed out a solitary nodule in right lung field on chest X-ray. Computed tomography (CT) scan showed an anterior mediastinal tumor and a solitary lung nodule in the right lower lobe. Extended thymectomy and partial resection of right lung was performed. Pathological diagnosis showed an invasive thymoma (type B3) and a pulmonary metastasis. Post operative radiotherapy was administered and she is doing well 19 months following the resection. Thymoma with a solitary synclonous pulmonary metastasis is rare and is classified into Masaoka stage IVb. Generally, thymoma cases with distant metastasis are not indication for operation. But, if radical resection is possible, operation is recommended for good prognosis.
我们报告一例伴有孤立性肺转移的胸腺瘤切除病例。一名63岁女性在胸部X线检查时发现右肺野有一个孤立结节。计算机断层扫描（CT）显示前纵隔肿瘤和右下叶一个孤立的肺结节。行扩大胸腺切除术及右肺部分切除术。病理诊断为浸润性胸腺瘤（B3型）伴肺转移。术后给予放疗，切除术后19个月她情况良好。伴有孤立性同步肺转移的胸腺瘤罕见，属于Masaoka IVb期。一般来说，有远处转移的胸腺瘤病例不是手术适应证。但是，如果能够根治性切除，建议手术以获得良好预后。
