Living with Lupus erythematosus tumidus

A rare type of chronic skin lupus with smooth pink to violet bumps on sun-exposed skin that heal without scars.

Understanding Lupus erythematosus tumidus

Lupus erythematosus tumidus is a rare type of chronic cutaneous (skin) lupus erythematosus.

It causes smooth, non-scarring pink to violet pimples (papules) on sun-exposed areas, such as the face, upper back, neck, trunk, and arms. They usually affect both sides of the body, and they normally clear without scars. People usually do not have other symptoms of systemic lupus. It can appear at a variety of ages.

Signs & symptoms

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

  • Smooth pink to violet bumps (papules)
  • Red raised patches (erythematous plaques)
  • Sensitivity to sunlight (photosensitivity)

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.
