Incontinentia Pigmenti

Incontinentia pigment! (Bloch-Sulzberger syndrome) is a rare neuroectodermal dysptasia. It is an X-linked dominant disorder caused by mutations in the IKBKG/NEMO gene on Xq28. Approximately 80% of patients have a deletion of exons 4 to 10. Incontinentia pigmenti has an estimated incidence of 0.7 cases per 100,000 births. In hemizygous males, it is usually lethal, while in females, it has a wide spectrum of clinical manifestations. Incontinentia pigmenti is a muttisystemic disease that invariably features skin changes. These changes are the main diagnostic criteria and they evolve in 4 stages, in association with other abnormalities affecting the central nervous system, eyes, teeth, mammary glands, hair, nails, skin, and other parts of the body. The aim of this brief review is to highlight the clinical features of this genodermatosis and underline the importance of case-by-case interdisciplinary management, including genetic counseling.
