[Intolerance to cow's milk proteins: cases contribution].
The authors report their own case-report about cow's milk protein intolerance observed in the last seven years in the gastroenterology-department of Pediatric Clinic in Pisa. They underline the symptomatologic polymorphism of the illness and, analysing the laboratory data, point out the absence of absolute diagnostic assurance tests. For this reason they conclude that at the present state the diagnosis of certainty is overall committed to the resolution of the symptomatology after exclusion-diet and following clinic relapse after milk load.
