Living with Malignant atrophic papulosis

A rare blood vessel disorder, also called Degos disease, that can cause white skin spots and affect the gut and other organs.

Understanding Malignant atrophic papulosis

Malignant atrophic papulosis, also called Degos disease, is a rare blood vessel disorder that slows or stops blood flow in affected vessels.

Symptoms depend on how much and where blood vessels are affected. Some people have only skin involvement, with porcelain-white spots. Others have more widespread disease. It is described in adults.

Signs & symptoms

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

  • Small raised skin bumps (papules)
  • Thinning of the skin (atrophy)
  • Abdominal pain
  • Nausea and vomiting
  • Bleeding in the digestive tract
  • Weight loss and tiredness

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 autoimmune and inflammatory disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
