Living with Linear atrophoderma of Moulin

A skin condition with slightly thinned, darker bands on the trunk or limbs that starts in childhood or adolescence.

Understanding Linear atrophoderma of Moulin

Linear atrophoderma of Moulin (LAM) is a skin condition with mildly thinned, darker band-like patches on the trunk or limbs.

The bands follow the lines of Blaschko. It begins in childhood or adolescence and does not progress. There is no inflammation beforehand and no later scleroderma.

Signs & symptoms

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

  • Darker band-like skin patches (linear hyperpigmentation)
  • Mildly thinned skin

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 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.
