Living with Actinic lichen planus

A rare form of lichen planus with mildly itchy, coin-shaped patches on sun-exposed skin.

Understanding Actinic lichen planus

Actinic lichen planus is a rare form of lichen planus, a condition that affects the skin and sometimes the mouth.

People develop mildly itchy, coin-shaped patches on sun-exposed areas such as the face, neck, and backs of the hands. It is extremely rare in Caucasians but more common in dark-skinned populations. GARD lists onset as any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD's summary lists these:

  • Mildly itchy skin
  • Coin-shaped patches
  • Patches on sun-exposed skin (face, neck, backs of hands)

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 skin, hair, and nail specialists.

  3. Ask which tests can help

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