Hypomelanosis of Ito (HI) appears to be the third most common neurocutaineous disease, second only to neurofibromatosis and tuberous sclerosis. Approximately three fourths of the patients with typical skin lesions have systemic manifestations. A few cases have been associated with musculoskeletal and neurological manifestations. Male-to-female ratios vary. The key sign consists of macular hypo pigmented skin lesions presenting by 2 years after birth in 90% patients.

Abstract


Hypomelanosis of Ito (HI) appears to be the third most common neurocutaineous disease, second only to neurofibromatosis and tuberous sclerosis. Approximately three fourths of the patients with typical skin lesions have systemic manifestations. A few cases have been associated with musculoskeletal and neurological manifestations. Male-to-female ratios vary. The key sign consists of macular hypo pigmented skin lesions presenting by 2 years after birth in 90% patients.
