title: Pulmonary infiltrate with eosinophilia in a 14-year-old child.
abstract: A prolonged case of pulmonary infiltrates with eosinophilia of the lung was submitted to a large immunological enquiry. The biological results, added to the immunofluorescence study of a lung biopsy, militated for a complex underlying immune mechanism with, on one hand IgE, eosinophils and mast cells, and on the other hand plasma cells and IgG.
