OverviewIncontinentia pigmenti produces darkly-pigmented swirling marks on the skin. It occurs more frequently in females. The skin lesions are divided into three stages: blisters (vesicles and bullae) are present at birth or within the first 6 to 7 weeks, followed by a rough wart-like (verrucous) stage, and lastly, swirled and bizarre patterns of dark pigmentation (hyperpigmentation) appear.
