Acquired Universal Melanosis (Carbon Baby Syndrome)



Generalized pigmentation in a child may be attributed to a wide range of disorders. Acquired universal melanosis (AUM), also known as carbon baby syndrome, is one such rare condition, characterized by progressive hyperpigmentation of the skin since infancy with histopathologic features of heavy melanization of the entire epidermis. Since its initial description, only a few cases of AUM have been described in the English-language literature. We describe here a case of a young child with AUM for its rarity and a few unusual features.
