通过肺良性肿块和肺癌的比较分析，了解肺良性肿块的临床特点及与肺癌的区别。方法总结手术治疗的肺良性肿块１３０例（Ａ组）的资料，并与同期手术的肺癌４７８例（Ｂ组）进行比较，从诊断、治疗和并发症的处理几个方面进行分析。结果Ａ组患者年龄小，病程长，临床大咯血相对较多，Ｘ线部分病灶内可见钙化和脂肪组织，手术中可见胸腔粘连多，术后严重并发症少、病死率低，与Ｂ组差异均有显著性。结论肺良性肿块一般年龄小、病程长。诊断不明者应积极手术，以免延误肺癌的治疗。确诊良性者应尽量作楔形切除，以保留尽可能多的正常肺组织
Through the comparative analysis of lung benign mass and lung cancer, the clinical features of benign pulmonary mass and its difference with lung cancer are known. Methods A total of 130 cases of benign pulmonary masses (group A) were surgically treated and compared with 478 cases (group B) of lung cancer undergoing surgery. The diagnosis, treatment and complications were analyzed. Results The patients in group A were young and had a long course of disease, and had a large amount of clinical hemoptysis. Calcification and adipose tissue were visible in some X-ray lesions. Thoracic adhesions were seen during surgery. There were fewer serious postoperative complications and lower mortality. Both are significant. Conclusion The benign lung masses are usually young and have a long duration. Those with unknown diagnosis should undergo active surgery to avoid delay in the treatment of lung cancer. Benign definite persons should try to make a wedge resection to retain as much normal lung tissue as possible
