What causes a butterfly rash?

A butterfly rash is most often associated with systemic lupus erythematosus, or lupus. Lupus is a chronic autoimmune disease that can have a serious and widespread effect on the body, including the skin, joints, muscles, and other organs.

In some cases, a red facial rash with a butterfly-like shape can appear on the face, but it is related to other causes besides lupus. The rash seen in these other diseases, disorders or conditions does not always involve the nose. They include:

  • Dermatomyositis (chronic disease characterized by muscle inflammation and weakness)
  • Drug photosensitivity (rash worsens with UV exposure)
  • Erysipelas (bacterial skin infection)
  • Pellagra (niacin, or vitamin B3 deficiency)
  • Rosacea (chronic, inflammatory skin condition)
  • Scarlet fever
  • Sunburn or windburn

What are the potential complications of a butterfly rash?

You can best minimize the serious and potentially life-threatening complications of lupus, which is the most common cause of a butterfly rash, by following your treatment plan and seeing your healthcare provider as recommended. Complications of lupus can affect almost any organ in the body and include:

  • Arthritis

  • Bleeding

  • Blood clots

  • Central nervous system damage and stroke

  • Frequent infections

  • Kidney damage and kidney failure

  • Liver damage

  • Myocarditis (inflammation of heart tissue)
  • Pleurisy

  • Seizures

  • Vasculitis

  • Worsening of the butterfly rash and other rashes on the body, especially with sun exposure
