- Incontinentia pigmenti (Syndrom Bloch-Sulzbeger) Incontinentia pigmenti (IP) is a rare, genetic disorder characterized by unusual patterns of discolored skin. The disorder is caused by excessive deposits of melanin (normal skin pigment).

IP is divided into 4 stages, which frequently overlap or appear together. During the first stage, which begins between birth and 6 months of age, there is inflammation accompanied by skin redness and spiral lines of small fluid-filled blisters. The second stage gradually develops with rough, warty skin growths which appear on the arms or legs and, sometimes, on the head or trunk. These growths, which are often arranged in the same spiral or linear pattern as in the first stage, usually resolve during infancy or early childhood. The third stage begins between 3 months and 2 years of age and is characterized by discolorations appearing in unusual patterns. The fourth stage consists of diminished pigmentation or atrophy in areas of previous discoloration.
