• Incontinentia pigmenti (Bloch-Sulzberger syndrome) is an uncommon genodermatosis that usually affects female infants. I reviewed 464 references from the world literature and found 653 apparently valid reports of patients with incontinentia pigmenti. Skin manifestations were found to be somewhat more common than previously reported, and systemic manifestations were found in 79.8% of the patients.
