Living with Annular lichen planus

A rare skin condition that causes ring-shaped, slightly raised purple patches.

Understanding Annular lichen planus

Annular lichen planus is a rare form of lichen planus that causes ring-shaped, slightly raised, purple patches on the skin.

Lichen planus is a condition that affects the skin and/or mouth. In the annular form, the patches have no central atrophy (tissue breakdown). Purely annular lichen planus is very rare, but ring-shaped patches show up in about 10% of all lichen planus cases. It can begin at any time in life.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet, but its summary describes the main skin finding:

  • Ring-shaped, slightly raised, purple skin patches
  • No tissue breakdown (atrophy) in the center of the rings

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.

  4. Connect with expert centers

    Autoimmune Association may keep lists of experts for this condition.
