Differential diagnoses include syndromic forms of ichthyosis, recessive X-linked ichthyosis and autosomal dominant ichthyosis vulgaris in mild forms, and CIE in case of erythroderma (see these terms). Ichthyosis is a family of genetic skin disorders characterized by dry, thickened, scaly skin. If an individual receives one working gene and one non-working gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms. A skin biopsy is required to make the diagnosis. Eine Erzahlung Von Hartmann von Aue.
