Pulmonary Eosinophilia

Abstract

A review of 450 cases reported in the literature plus 16 observed by the authors. This group of diseases is classified as follows: (1) simple pulmonary eosinophilia (Loffler''s syndrome); (2) prolonged pulmonary eosinophilia, without asthma; (3) pulmonary eosinophilia with asthma; (4) tropical pulmonary eosinophilia; (5) polyarteritis nodosa. The pathological findings in the different types classified suggest that they are different grades of the same fundamental process.
