Eosinophilic enteritis with perforation

A case of eosinophilic granuloma of the gastrointestinal tract with free perforation is described. The authors believe this is the first such case to be published. The patient, a 60-year-old woman, had no history of allergy. At laparotomy, 100 ml of pus was aspirated. A 42-cm section of small bowel, containing multiple punched-out ulcers, was excised. The mucosa and submucosa of the operative specimen were edematous; there was a moderate inflammatory infiltrate containing numerous eosinophils and neutrophils. The lesion appeared to represent a local reaction to some antigen with resultant eosinophilic infiltration.
