Living with Dermatomyositis

Information, shared experiences and research connections for people living with dermatomyositis and those who support them.

Understanding Dermatomyositis

Dermatomyositis is an autoimmune condition, meaning the immune system mistakenly attacks the body, that causes muscle inflammation and weakness along with a distinctive skin rash.

Its exact cause isn't known; weakness may come on suddenly or build over weeks to months, and the course varies, with some people, especially children, seeing symptoms go away completely.

Signs & symptoms

Dermatomyositis affects both the skin and the muscles. Common signs include:

  • A purple-red rash, often on the upper eyelids, face, neck or upper body
  • Red bumps over the knuckles and other joints
  • Weakness that makes it hard to climb stairs, stand up or raise your arms
  • Muscle stiffness or soreness
  • Trouble swallowing
  • Shortness of breath or tiredness

Tell your care team about new or changing symptoms.

Diagnosis

  1. Exam and history

    A clinician looks closely at the skin and checks muscle strength.

  2. Blood and other tests

    Blood tests for muscle enzymes and immune markers, plus tests such as EMG, MRI, or lung and swallowing studies, may be used.

  3. Skin and muscle biopsy

    A small piece of skin and muscle may be studied under a microscope to help confirm the diagnosis.

Care & treatment

Monitoring
Follow-up may include muscle strength checks, blood tests, and checks of the lungs and heart, plus cancer screening, since cancer can be linked to dermatomyositis.
Treatment
Care often starts with medicines that calm inflammation, which are lowered slowly over time, and other medicines that quiet the immune system may be added.
Your plan
People respond differently, so your care team may adjust the plan if symptoms continue or come back.

Discuss benefits, risks and follow-up with your care team.

Everyday life

Tracking changes over time can help you and your care team.

  • Note when everyday tasks like climbing stairs, standing up or lifting your arms get harder or easier.
  • Take dated photos of rash changes to share at visits.
  • Ask your care team about protecting your skin from the sun, since skin can be sensitive to sunlight.
