Dyschromatosis symmetrica hereditaria (also known as reticulate acropigmentation of Dohi, and symmetrical dyschromatosis of the extremities) is a rare autosomally inherited dermatosis. It is characterized by progressively pigmented and depigmented macules, often mixed in a reticulate pattern, concentrated on the dorsal extremities.: 855 It presents primarily in the Japanese, but has also been found to affect individuals from Europe, India and the Caribbean.

- Hypopigmented macules
