Dyschromatosis symmetrica hereditaria: report of a sporadic case.

A group of pigment disorders is included under the denomination of "dyschromatosis". Dyschromatosis symmetrica hereditaria is a dominant autosomal genodermatosis mostly reported in Eastern countries. It has been rarely reported in nonoriental races and spontaneous cases are scarce. We report a spontaneous case in the West, a boy 6 years of age, with a typical presentation and who was confused initially with vitiligo.
