[Chronic eosinophilic pneumonia. Apropos of 2 cases].

Pathologic findings in two patients with no previous history of atopic affections were apical pulmonary infiltration, a marked general syndrome with altered general state and hyperthermia, a productive cough, and a circulating eosinophilia. Clinical manifestations and the particular radiographic images of homogeneous condensation of the two apices in the form of "helmet crests", together with the typical course during corticoid treatment and histopathologic findings in one case, established a diagnosis of chronic eosinophil pneumonia. The principal characteristics of this affection, as exemplified by these two cases, are analyzed.
