Carbon baby syndrome: An unusual cause of progressive generalized melanosis

Abstract

Universal acquired melanosis, also referred to as Carbon baby syndrome, is a rare cause of progressive generalized hyperpigmentation of skin and mucosa. We describe a case of a 2-year-old boy with diffuse darkening of skin and mucosa for 3 months of age. Histopathology revealed increased melanin in the basal and suprabasal layers of the epidermis.
