RESUMO
Cow's milk allergy (CMA) is an immune-based disease that has become an increasing problem. The diagnosis and management of CMA varies from one clinical setting to another and represents a challenge in pediatric practice. In addition, because nonallergic food reactions can be confused with CMA symptoms, there is an overdiagnosis of the disease. In response to these situations, pediatric specialties from recognized institutions throughout Latin America decided to develop a clinical guideline for diagnosis and management of cow's milk allergy. These guidelines include definitions, epidemiology, pathophysiology overview, clinical and evidencebased recommendations for the diagnosis and treatment of CMA. They also include prevention and prognosis sections and identify gaps in the current knowledge to be addressed through future research.

The goal of this paper is to present a clinical case of a 4 year old boy, with hepatomegaly, splenomegaly and intestinal lipid infiltration due to a inborn error of lipid metabolism known as cholesterol ester storage disease. The main clinical manifestations were hepatomegaly, splenomegaly, hypertriglyceridemia, hypercholesterolemia. Duodenal endoscopy showed a yellow appearance of the mucous, and the histological study revealed the presence of macrophages with granular material. Liver biopsy showed steatosis infiltration at the hepatocytes, and macrophages with lipids. This disease is due to a lisosomal acid lipase partial deficiency, that is a glicoprotein that metabolize the hydrolysis of ester of cholesterol and triglycerides. The name of this pathology is cholesterol ester storage disease, but when the deficiency is total the name is Wolman's disease. We conclude that in all the children whit a clinical picture of hepatomegaly, splenomegaly, hypertriglyceridemia and hypercholesterolemia it is obligatory to rule out an inborn error of lipid metabolism like Wolman's disease or cholesterol ester storage disease.
