我们通过对煤工尘肺的病理形态学观察,认为肺气肿是煤工尘肺的基本病变之一;煤斑与气肿的组合应列为独立的一型,它具有病理和临床的重要意义。现报告如下: 材料与方法1976年以来,我们共收集了24例煤工尘肺尸检标本,以其中尘斑气肿病变为主的16例加以讨论。16例患者均为男性,年龄为34～60岁,平均50.6岁;最短工龄6年,最长34年,平均20.8年。所有的标本均用10%福尔马林固定,常规取材20块组 We observed the pathomorphology of coal workers ’pneumoconiosis that emphysema is one of the basic pathological changes of coal workers’ pneumoconiosis; the combination of coal and emphysema should be classified as independent type, which has pathological and clinical significance. Now report as follows: Materials and methods Since 1976, we collected a total of 24 cases of coal workers pneumoconiosis specimens, including dust plaque emphysema lesions mainly 16 cases to be discussed. All 16 patients were male, with an average age of 34.6 years (average 50.6 years). The minimum length of service was 6 years and the longest was 34 years (average 20.8 years). All specimens were fixed with 10% formalin, routinely drawn 20 groups
