Definition    Return to top

Ichthyosis vulgaris is a common skin disorder passed down through families that leads to dry, scaly skin.

Causes    Return to top

Ichthyosis vulgaris is one of the most common of the inherited skin disorders. It may begin in early childhood, before age 4. In most cases one parent is affected -- and each child has a 50-50 chance of developing the condition.

The condition is often more noticeable in the winter. It may occur along with atopic dermatitis, keratosis pilaris (small bumps on the back of the arms), or other skin disorders.

Symptoms    Return to top

The dry, scaly skin is usually most severe over the legs but may also involve the arms, hands, and middle of the body. Persons with this condition may also have many fine lines over the palm of the hand.

Exams and Tests    Return to top

Your doctor can usually diagnose this condition by looking at your skin. Tests may be needed to rule out other possible causes of dry, scaly skin.

Your doctor will ask you if you have a family history of similar skin dryness.

Treatment    Return to top

Your doctor will recommend heavy duty moisturizers. Creams and ointments work better than lotions. Apply these to moist skin immediately after bathing. You should use mild, non-drying soaps.

Your doctor may tell you to use moisturizing creams that contain chemicals that help skin to shed normally, including lactic acid, salicylic acid, and urea.

Outlook (Prognosis)    Return to top

Ichthyosis vulgaris can be a nuisance, but it rarely affects your overall health. The condition usually disappears during adulthood, but may return years later.

Possible Complications    Return to top

A bacterial skin infection may develop if scratching causes openings in the skin.
