[Reye's syndrome: pathological aspects].

A clinical and statistical review of Reye's syndrome is made, reporting the case of a female seven months old infant with disturbances of the digestive tract associated to hepatomegaly, convulsive crises, maculopapular exanthema, extreme hypoglycemia, hyperammoniemia and high blood urea. The post-mortem study showed fine drop diffuse liver steatosis, renal tubuli steatosis, focal steatosis of myocardial fibers, generalized meningoencephalic edema and viral pneumonia. These clinico-pathologic characteristics lead to the diagnosis of Reye's syndrome, an infrequent entity in our milieu judged by national literature.
