Abstract Dyschromatosis universalis hereditaria (DUH) is a rare genodermatosis. It is clinically characterized by the symmetrical distribution of hyperpigmented and hypopigmented macules that give an impression of mottling. The cosmetic disfigurement accompanying DUH can have a significant psychosocial impact on the patient. We report a case of a 34-year-old male with DUH having unusual involvement of oral mucosa and palms.
