Incontinentia pigmenti (IP) is a rare affection inherited as X-linked dominant disease. It is usually lethal in male infants. IP can affect ectodermal tissues such as the skin, teeth, eyes, bones, and the central nervous system. Skin lesions occur mostly during the neonatal period and are characterized by a classic progression in 4 stages leading to hyperpigmentation. We report on the case of a female neonate presenting on the 3rd day of life with seizures without obvious cause, in which the diagnosis of IP was made 1 week later when skin lesions appeared.
