Acquired universal melanosis also known as carbon baby syndromeis a rare condition of progressive generalised hyperpigmentation of skin and mucosal lining with histopathological features of increased epidermal basal layer melanisation. We diagnosed two siblings of the same family who developed progressive darkening of skin and mucosa since infancy with histopathological evidence of excessive melanin pigmentation of the epidermis.
