[Cutaneous mastocytosis. Description of 4 cases]

The Authors describe four cases of cutaneous mastocytosis observed during paediatric age. They notice that the disease presents itself with a clinical polymorphous situation which sometimes exceeds the limits of the cutaneous gambit, until the illness reveals itself a systemic serious disease. Besides they point out uncertain etiopathogenesis, the utility of a correct diagnostic approach and the utility of a therapy which is continually in evolution.
