Living with Lamellar ichthyosis

An inherited skin condition in which babies are born in a tight, clear membrane and later have large, dark, plate-like scales.

Understanding Lamellar ichthyosis

Lamellar ichthyosis is an inherited condition that mainly affects the skin.

Babies are typically born with a tight, clear sheath called a collodion membrane, which dries and peels in the first weeks. After that, they have scaly skin and eyelids and lips that turn outward. Large, dark, plate-like scales cover most of the body. Infants may develop infections, dehydration, and breathing problems. Hair loss, nail changes, less sweating, heat sensitivity, and thick palms and soles can also occur.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Large, plate-like scales
  • Dry skin
  • Eyelids turned outward (ectropion)
  • Thin or missing hair and eyebrows
  • Nail changes
  • Itching

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Foundation for Ichthyosis and Related Skin Types may keep lists of experts for this condition.
