Dyschromatosis universalis hereditaria: report of six cases from a family.

Dyschromatosis universalis hereditaria (DUH) is a rare pigmentary disorder characterized by the presence of mottled hyperpigmented and hypopigmented macules over the trunk, extremities, and face. We have presented a case series comprised of six members of a family who had numerous hyperpigmented and hypopigmented macules distributed all over the body. Histological findings were suggestive of dyschromatosis universalis hereditaria.
