We report a 3-year-old boy born with light brown skin that progressively became much darker. The color change was insidious in onset at the age of 3 months, asymptomatic, and progressive involving the entire body surface. Hyperpigmentation may be congenital or acquired, hereditary or nonhereditary, localized or universal, of known or unknown origin. Universal acquired melanosis is a rare form of hyperpigmentation, which has been synonymously referred to as ''carbon baby.''
