Extensive morphological and biochemical studies were carried out on two sibling cases of ichthyosis linearis circumflexa. The condition was found to be similar to psoriasis in the following ways: effectiveness of PUVA therapy, psoriatic changes on light and electron microscopy, high urinary polyamine levels, elevation of several enzyme activities in the scales, and a remarkable change in keratin molecules. These results may reflect an increased epidermal proliferation with a reduced epidermal transit time, as occurs in psoriasis.
