Common ichthyosis; Fish scale disease
Definition of Ichthyosis vulgaris
Ichthyosis vulgaris is a common skin disorder passed down through families that leads to dry, scaly skin.
Causes, incidence, and risk factors
Ichthyosis vulgaris is one of the most common of the inherited skin disorders. It may begin in early childhood, before age 4. The condition is inherited in an autosomal dominant pattern. That means you only need to get the abnormal gene from one parent in order for you to inherit the disease.
Signs and tests
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 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.
Ichthyosis vulgaris can be a nuisance, but it rarely affects your overall health. The condition usually disappears during adulthood, but may return years later.
