Eosinophilic enteritis associated with chronic eosinophilic pneumonia.

A case of eosinophilic pneumonia and eosinophilic infiltration of the small bowel and colon is reported. The patient presented with nonspecific chest and abdominal symptoms, and lack of response to therapy for presumed pneumonia. Further investigation including lung, muscle, and gastrointestinal tract biopsies revealed eosinophilic infiltration of the lung and gastrointestinal tract, an association that does not appear to have been previously documented.
