Causes and Risks

Ichthyosis vulgaris is one of the most common of the inherited skin disorders. It may begin in early childhood, before a child is 4 years old. In most cases one parent and one-half of the children will be affected. It usually disappears during adulthood, but may recur when elderly.

Ichthyosis involves development of dry, scaly skin. It is usually most severe over the legs but may also involve the arms, hands, and trunk in some cases. It is usually associated with many fine lines over the palm of the hand. The condition is often more noticeable in the winter. It may be associated with atopic dermatitis, keratosis pilaris (small bumps on the back of the arms), or other skin disorders.
