A 72-year-old woman developed left pneumothorax 14 months after the first operation of a gingival carcinoma. The chest X-ray films and computed tomographic scans on admission revealed left pneumothorax and 2 lesions with a thin-walled cavity in the upper lung field. They seemed to be pulmonary metastasis from a carcinoma of gingiva and one of them ruptured into the pleural cavity. As airleak continued after tube thoracostomy, wedge resections of 2 lesions were performed through thoracotomy. Postoperative histological examination revealed that both of the lesions were moderately differentiated squamous cell carcinoma and they were the same histological findings as the gingival carcinoma excised previously. Pulmonary metastasis from a carcinoma of gingiva is rare, while it may be thought 1% of metastatic lung tumors. And also pulmonary metastasis is unusual cause of pneumothorax, especially without chemotherapy for it. We reported the very rare case of pneumothorax due to pulmonary metastasis from a carcinoma of gingiva.
一名72岁女性在牙龈癌首次手术后14个月出现左侧气胸。入院时胸部X线片和计算机断层扫描显示左侧气胸以及上肺野有2个薄壁空洞病变。它们似乎是牙龈癌的肺转移灶，其中一个破入胸腔。胸腔闭式引流术后漏气仍持续，遂通过开胸手术对2个病变进行楔形切除。术后组织学检查显示，这2个病变均为中分化鳞状细胞癌，组织学表现与之前切除的牙龈癌相同。牙龈癌的肺转移很少见，可能占转移性肺肿瘤的1%。而且肺转移也是气胸的不常见原因，尤其是在未进行化疗的情况下。我们报告了这例因牙龈癌肺转移导致气胸的极为罕见的病例。
