Fuldauer and Kuijpers (1964) described a pigmentary anomaly in many members of a Dutch family. Although the paper was entitled 'Incontinentia Pigmenti,' the distribution of the hyperpigmentation was quite different, being located on the wrists, hands, and neck and less consistently on the axillary folds, dorsa of the feet, and lines of the hands. Furthermore, incontinentia pigmenti is probably an X-linked dominant lethal in males. Many males were affected in this family.
