In recent years, more and complex clinical syndromes, from reactive (secondary) to eosinophilic leukemia are increasingly considered by doctors different specialties. The aim our work was present a case secondary in child with minimal manifestations. Highlights: Sometimes patient is an unexpected finding physician, especially if complaints scanty, nonspecific, objective examination does not reveal any significant health abnormalities. presented case, (reactive) peripheral diagnosed due intestinal damage induced food allergens. This practical interest physicians, presenting eosinophilia, which eventually proved be mixed IgE/ non-IgE mediated allergy manifesting as enterocolitis. IgE-mediated mechanism evidenced high level IgE its decrease administered elimination diet; delayed-type response low severity manifestations allergy, well suggest allergy. this particular laboratory changes (blood increase levels specific IgE) associated scarce symptoms. An opposite situation observed, especially, young children where disease manifests pronounced pattern enterocolitis absence changes.
