Cutaneous Lupus Erythematosus

Cutaneous lupus erythematosus is a manifestation of the autoimmune disease systemic lupus erythematosus (SLE) that affects the skin. It may be triggered by sun exposure.

Cutsaneous lupus is classified into three main types:

  • Acute cutaneous lupus– often presents as a butterfly rash with redness and irritation over the cheeks and nose.
  • Subacute cutaneous lupus- manifests as a red, raised, scaly rash on sun-exposed areas of the body. It may mimic psoriasis.
  • Chronic cutaneous lupus- also known as discoid lupus, and presents with round red to purple scaly sores on the face and scalp, and heals with discolored scarring.
