[An comparative analysis of the radiographic appearances and the pathologic findings in anthracosilicosis and anthracosilicosis associated with tuberculosis].

Pulmonary tuberculosis is a serious complication of anthracosilicosis and a promoting factor for death. It is very difficult to distinguish the advanced stage of atypical anthracosilicosis from anthracosilicosis associated with tuberculosis by the chest radiograph when the tubercule bacili is negative in sputum, but it is necessary for physician to treat and administrate. In order to probe into the differential diagnosis of these two diseases author made a comparison analysis between the radiographic appearances and the pathological findings of 21 autopsies cases which were clinically diagnosed as anthracosilicosis associated with tuberculosis. There were 8/21 cases (38.1%) of misdiagnosis before the misdiagnosis there were the lack of series observation on the similarities and differences in radiographic appearances between these two diseases and neglect of sputum examination. The main points of clinical differentiation between them were summed up.
