Disseminated Ulcerations in Allergic Eosinophilic Gastroenterocolitis

An infant with allergic eosinophilic gastroenterocolitis is described. The patient presented with vomiting, diarrhea, gastrointestinal bleeding, and failure to thrive. Anemia, hypoproteinemia, and peripheral eosinophilia were also present. Gastrointestinal endoscopy revealed multiple mucosal ulcerations in the stomach, small intestine, and colon. Histological study of the affected areas showed infiltration of the mucosa by eosinophils, increased mucosal IgE plasma cells, and activated intraepithelial lymphocytes. Treatment with corticosteroids resulted in clinical and histological remission.
