[Considerations on pleural puncturo biopsy, based on the results of an analysis of 100 samples].

Results are given on 100 cases in which pleural bioptic puncture (PBP) has been performed for diagnosis purposes. The data given in the study show the large possibilities to apply this method, readily acceptable by patients. The high diagnosis value of PBP method in based on strictly objective criteria. Stress is laid upon the contribution of the method in precising the etiology of pleural fluids, which, up to the application of PBP, were labelled as having an "undetermined" etiology. The right therapeutic measures to be taken on precise diagnosis are also stressed in the study.
