Is Livedoid vasculopathy contagious?

Livedoid vasculopathy is not a contagious disease and cannot be spread to others through touch, bodily fluids, or any form of social contact. It is a chronic, non-infectious inflammatory condition of the small blood vessels in the skin, meaning there is zero risk to family members, caregivers, or friends when interacting with someone who has the condition.

What causes Livedoid vasculopathy?

Livedoid vasculopathy is considered a localized, occlusive vasculopathy. Rather than being caused by a virus or bacteria, it results from the clotting of blood within the small vessels of the dermis, which leads to tissue ischemia (lack of blood flow) and painful ulcerations. While the exact underlying mechanism remains a subject of ongoing research, it is frequently associated with hypercoagulable states—conditions where the blood is prone to clotting—or underlying autoimmune disorders.

Why is there confusion regarding contagion?

The confusion often stems from the visual appearance of Livedoid vasculopathy, which presents as painful, purpuric lesions and porcelain-white scars (atrophie blanche). Because these skin changes can look dramatic or "infectious" to the untrained eye, patients sometimes face social stigma. It is important to clarify that Livedoid vasculopathy is an internal vascular process, not a skin infection, and poses no public health risk.

Are there environmental or external triggers?

While Livedoid vasculopathy is not infectious, certain environmental factors can exacerbate symptoms for those already diagnosed. Patients often report that their condition flares in response to:

• Prolonged standing or physical trauma to the lower extremities.


• Exposure to cold temperatures, which can further constrict blood vessels.


• Hormonal changes or the use of oral contraceptives.


• Underlying inflammatory triggers that increase blood viscosity.

Next steps

• Consult a board-certified dermatologist or a vascular specialist to discuss personalized management plans, such as anti-platelet or anti-coagulant therapies.


• Connect with the 15 members currently sharing experiences with Livedoid vasculopathy on DiseaseMaps.org to find community support.


• Keep a symptom diary to identify if specific environmental triggers correlate with your personal Livedoid vasculopathy flares.
