周围型肺癌在支气管肺癌中占一定比例,正确的病理诊断及合理治疗,将会获得良好疗效。但是,肺癌病理形态学复杂,不同肿瘤形态各异,同一肿瘤的不同部位结构也不尽相同,诊断上往往有一定困难。目前应用电子显微镜,通过光镜与电镜的相互配合,对肺癌形态可进一步了解。本文对20例周围型肺癌进行形态学观察,并对其组织发生学加以分析。 Peripheral lung cancer accounts for a certain proportion of bronchial lung cancer. Correct pathological diagnosis and reasonable treatment will yield good results. However, the pathological morphology of lung cancer is complex. Different tumors have different shapes. The structure of different parts of the same tumor is also not the same. Diagnosis is often difficult. The current application of electron microscopy, through the cooperation of light and electron microscopy, can further understand the shape of lung cancer. In this paper, 20 cases of peripheral lung cancer were observed by morphological observation and histogenetics were analyzed.
