abstractsDyschromatosis universalis hcreditaria is a rare autosomal dominant inherited disease characterized by generalized hyper-and hypo-pigmentation of the skin. Most of the reported cases of this disease are from east Asian. Early studies suggested that dyschromatosis symmetrica hereditaria might be a subtype of this disease. However, recent studies on pathogenic genes have revealed that dyschromatosis symmetrica hereditaria and dyschromatosis univcrsalis hereditaria belong to two distinct disease entities.
