How do I know if I have Degos Disease?

Degos disease, or malignant atrophic papulosis, is a rare vasculopathy characterized by distinctive porcelain-white skin lesions with erythematous borders. If you suspect you have Degos disease, you should seek an evaluation from a dermatologist or rheumatologist to differentiate these specific skin findings from more common dermatological conditions.

What are the early signs of Degos disease?

The hallmark of Degos disease is the appearance of small, round, reddish papules that eventually develop a depressed, white, porcelain-like center. These lesions are typically found on the trunk and extremities. While the skin is the most visible indicator, systemic Degos disease can involve the gastrointestinal tract and central nervous system due to the underlying small-vessel occlusion.

How can I perform a self-assessment?

Monitoring your skin is the primary step in self-assessment for Degos disease. Look for these specific patterns:

• Lesions that do not heal or resolve like typical acne or insect bites.


• The presence of a "porcelain-white" center surrounded by a raised red rim.


• Unexplained abdominal pain or neurological symptoms (headaches, weakness) occurring alongside these skin changes.


• The lesions are typically asymptomatic but persist over time.

When should I seek urgent medical evaluation?

You must seek immediate medical attention if you experience severe abdominal pain, as Degos disease can cause bowel perforation, or if you develop sudden neurological deficits. When speaking to your doctor, explicitly mention your concern regarding a "vasculopathy" or "small-vessel occlusion" and ask for a skin biopsy of a new lesion, which is the gold standard for diagnosing Degos disease.

How do I advocate for my health?

Because Degos disease is exceptionally rare, many physicians may not have encountered it. If your concerns are dismissed, bring printed literature from reputable sources like NIH GARD or the Degos disease patient community at DiseaseMaps.org. Request a referral to a center of excellence or a specialist in rare vasculitis.

Next steps

• Schedule an appointment with a board-certified dermatologist for a skin biopsy.


• Keep a photographic log of your skin lesions to track changes over time.

• Consult a rheumatologist to screen for systemic involvement.
