A mother and two children with nonbullous congenital ichthyosiform erythroderma.

A mother and her two daughters were all afflicted by congenital nonbullous ichthyosis. The clinical and ultrastructural picture are in accordance with recessive congenital ichthyosiform erythroderma. The mode of inheritance for the children is assumed to be by pseudo-dominance. Nonbullous congenital ichthyosiform erythroderma and lamellar ichthyosis are probably heterogeneous.
