[Incontinentia pigmenti (the Bloch-Sulzberger syndrome)].

The course and histologic skin signs are described at the stage of inflammation in 2 cases of incontinentia pigmenti (IP) or the Bloch-Sulzberger syndrome. In the authors' opinion, the pigmentary stage of skin lesion in IP does not replace the warty stage, but accompanies it or the inflammatory one as blebs disappear. In IP, the latter contain eosinophils; there is plasma and cell infiltration with a touch of eosinophils and connective tissue matrix lysis in the area of blebs.
