title: [Eosinophilic proctocolitis induced by foods. Report of a case].
abstract: The food-induced eosinophilic proctocolitis is a major cause of blood-tinged stools and appears in the first two months of life. The infant is generally described as well, but the clinical features and laboratory results are often nonspecific. We present an early infant with fresh blood stools at 50 days. The colonoscopy and biopsy of the rectum and lower sigmoid revealed lymphoid nodular hyperplasia of the submucose and eosinophil infiltration (40 to 50 per high power field) of the lamina propria and intraepithelial. Elimination of the offending protein from the diet, through the use of an extensively hydrolyzed casein-based formula and soy, lead to clinical resolution of bleeding at 48 hours. We made a review of the case.
