Short answer · Medically reviewed summary · Last updated: 2026-05-08
Degos disease, also known as malignant atrophic papulosis, is an exceptionally rare, life-threatening condition characterized by the occlusion of small-to-medium-sized blood vessels, leading to tissue death (infarction) in the skin, gastrointestinal tract, and central nervous system. Because the disease causes widespread blood vessel damage, it can affect multiple organ systems simultaneously, often requiring a multidisciplinary medical approach. What are the two types of Degos disease? Medical literature typically distinguishes between two forms of Degos disease.

What is Degos Disease? Plain-language, medically reviewed definition plus the lived reality told by patients.
Degos disease, also known as malignant atrophic papulosis, is an exceptionally rare, life-threatening condition characterized by the occlusion of small-to-medium-sized blood vessels, leading to tissue death (infarction) in the skin, gastrointestinal tract, and central nervous system. Because the disease causes widespread blood vessel damage, it can affect multiple organ systems simultaneously, often requiring a multidisciplinary medical approach.
What are the two types of Degos disease?
Medical literature typically distinguishes between two forms of Degos disease. The systemic form is the most severe, involving the skin alongside the gastrointestinal tract and brain. The benign or "cutaneous-only" form of Degos disease is limited to the skin and does not progress to involve internal organs, which significantly changes the prognosis for the patient.
Which body systems are affected by Degos disease?
The pathophysiology of Degos disease involves a process called obliterative vasculopathy, where the lining of the blood vessels becomes inflamed and blocked. The most common manifestations include:
- Skin: Small, porcelain-white papules with red borders, which are the hallmark sign.
- Gastrointestinal: Bowel perforations and abdominal pain resulting from blocked blood flow to the gut.
- Neurological: Strokes, headaches, or cognitive changes due to restricted blood flow in the brain.
How rare is Degos disease and who does it affect?
Degos disease is extremely rare, with fewer than 200 cases reported in medical literature globally. It can affect individuals of any age, though it is most commonly diagnosed in adults between 20 and 50 years old. There is no known geographic, ethnic, or gender preference for Degos disease, though the rarity of the condition makes it difficult to establish precise epidemiological statistics.
What differentiates Degos disease from other conditions?
Unlike other vasculitis conditions, Degos disease is characterized by a specific type of vessel occlusion that does not typically respond to standard anti-inflammatory treatments. Its unique skin lesions—often described as "porcelain-white"—are the primary clinical indicator that helps physicians distinguish it from lupus, dermatomyositis, or other systemic vascular disorders.
