Hypomelanosis of Ito with cerebral malformation.

Syndromic forms of cortical maldevelopment continue to be a curiosity. Hypomelanosis of Ito (HI) is the presence of whirled hypochromic skin lesions often associated with nondermatological manifestations. The polymorphism of brain abnormalities associated with HI is well known. We report three cases of Hypomelanosis of Ito, occuring in infants and associated with cerebral malformation.
