[Eosinophilic pleurisy (a study of 27 cases)].

After reviewing the specific literature mainly on cytokines role in eosinophilic pleural chemotaxis, the study on 27 cases of eosinophilic pleurisy is presented. Only 3 cases were malignant pleurisies. The ratio between blood and pleural fluid eosinophils has no semiologic significance. Tuberculosis and parasitoses have no special significance. Autonomous eosinophilic pleurisies are regarded as a distinct nosologic entity. Their prognosis is favourable. The glucocorticoids are the choice treatment.
