What is ichthyosis?
"Ichthyosis (ick-thee-o-ses) is the name of a rare genetic skin disorder. Since it's a genetic mutation, it isn't contagious--you can't "catch" it. Ichthyosis causes the skin to build up and scale, causing it to be extremely dry, among other problems.
Most types of ichthyosis are present at birth, and are life-long. Currently, there is no cure, only treatments."
Ichthyosis is the name given to at least 28 genetic skin disorders. All 28 types are characterized by dry, thickened, scaly, or flaky skin. The skin is said to resemble the scales on a fish, which is why the word ichthyosis comes from the ancient Greek word ichthys which means "fish." The most common type of ichthyosis is ichthyosis vulgaris. A doctor can diagnose the condition by looking at the skin or viewing family history. There is no way to prevent ichthyosis, but it may be treated using topical creams and emollient oils.
