Food protein-induced enterocolitis syndrome, an uncommonly encountered pathologic entity

摘要

Biopsies were taken from the esophagus, gastric body/antrum, duodenum, ileum, colon, and rectum. Besides the esophagus, the entire GI tract showed inflammatory changes, quite marked in some locations (Figs. 1-3). The stomach showed mild active gastritis with signs of chronic disease, including a hypercellular lamina propria with an in- filtrate containing plasma cells, lymphocytes, and a few eosinophils and scattered neutrophils. The duodenum showed more involvement, with an acute and chronic inflammatory infiltrate villous blunting and fo- veolar metaplasia, suggesting a more protracted course.
