We encountered 2 cases of intrapulmonary lymph node. Case 1 was in a 48-year-old woman who had been given a diagnosis of progressive systemic sclerosis. Case 2 was in a 49-year-old woman with idiopathic pulmonary fibrosis. In each patient, a follow-up chest CT scan showed a pulmonary nodule, which could not be seen on chest X-ray film. Each nodule has an irregular margin and a linear shadow resembling pleural indentation. Histological examination of the open biopsy specimens revealed that these nodules were intrapulmonary lymph nodes surrounded by interstitial pneumonia. Previous case reports and these 2 cases indicate that unless a thoracotomy is done intrapulmonary lymph nodes are difficult to distinguish from lung cancers.
我们遇到了2例肺内淋巴结病例。病例1为一名48岁女性，被诊断为进行性系统性硬化症。病例2为一名49岁患有特发性肺纤维化的女性。在每位患者中，胸部CT随访扫描显示有一个肺结节，而胸部X光片上未见该结节。每个结节边缘不规则，有类似胸膜凹陷的线状阴影。对开放活检标本的组织学检查显示，这些结节是被间质性肺炎包围的肺内淋巴结。既往病例报告及这2例病例表明，除非进行开胸手术，否则肺内淋巴结很难与肺癌区分开来。
