Dyschromatosis symmetrica hereditaria (DSH) is a rare autosomal dominant genodermatosis that prominently occurs among Japanese and Korean individuals. Dyschromatosis symmetrica hereditaria presents with a mixture of hyperpigmented and hypopigmented macules distributed on the face and the dorsal aspects of the extremities. We report a case of a 4-year-old girl with DSH and review the pertinent features of this genodermatosis.
