Lamellar ichthyosis is a rare skin condition that affects newborns.
Causes, incidence, and risk factorsLamellar ichthyosis is passed down through families (inherited).
SymptomsThe baby's skin appears scaly, and layers of skin fall off (are shed).
TreatmentMoisturizers containing urea and ammonium lactate may help. Also, retinoid medications such as tazarotene may be used on the skin (topically).
Lamellar ichthyosis is a rare skin condition that appears at birth and continues throughout a person's life.
Causes, incidence, and risk factorsLamellar ichthyosis is passed down through families (inherited). Both parents must have at least one abnormal gene to pass it to their children.
SymptomsA baby is born with a collodian membrane -- a shiny, waxy layer of skin that sheds within the first 2 weeks of life. Red, scaly skin remains underneath. It resembles the surface of a fish.
TreatmentMoisturizers containing urea, ammonium lactate, or other alpha-hydroxy acids may help. Also, retinoid medications such as tazarotene may be used on the skin (topically).
Gene therapy to correct the genetic defect may be possible in the future.
ComplicationsWhen the collodian membrane is shed, babies are at risk for infection.
Later in life, eye problems may occur because the eyes cannot close completely.

Many individuals with ichthyosis, particularly lamellar ichthyosis, do not sweat normally. The thickness of their skin and the scale does not allow their sweat to reach the surface of their skin and cool them effectively. In very hot and humid weather they are at risk for overheating, heat exhaustion, and heat stroke.
