However, biopsy specimens obtained from the esophagus, stomach, and duodenum revealed eosinophilic infiltration at 10-15 cells/high -power field (Fig. 4A, B). Biopsy specimens obtained from the terminal ileum to the rectum revealed eosinophil infiltration at 30-100 cells/high-power field (Fig. 4C, D).
