Lamellar ichthyosis


Definition:

Lamellar ichthyosis is a rare skin condition. It appears at birth and continues throughout life.

Causes:

Lamellar ichthyosis is passed down through families. Both parents must have at least one abnormal gene to pass the condition to their children.

Symptoms:

A baby with this condition is born with a shiny, waxy layer of skin called a collodian membrane. The membrane sheds within the first 2 weeks of life. The skin underneath the membrane is red and scaly. It resembles the surface of a fish.

Treatment:

Moisturizers containing medicines such as urea or other substances may help shed dead skin layers. Also, medicines that contain retinoids may be applied to the skin.

Possible Complications:

Babies are at risk for infection when they shed the collodian membrane.

Eye problems may occur later in life because the eyes cannot close completely.
