What is Livedoid vasculopathy

TL;DR: Livedoid vasculopathy is a rare, chronic inflammatory vascular disease characterized by painful, recurring ulcers on the lower legs that heal into ivory-white, star-shaped scars known as atrophie blanche. It results from the blockage of small blood vessels in the skin, often requiring long-term management by dermatologists and vascular specialists.

What exactly is Livedoid vasculopathy?

Livedoid vasculopathy is a localized condition where the small blood vessels in the dermis (the deeper layer of skin) become inflamed and occluded by blood clots. This process, known as thrombotic vasculopathy, prevents oxygen and nutrients from reaching skin tissue, leading to the formation of painful lesions. While 15 members of the DiseaseMaps.org community are currently navigating this diagnosis, it remains a rare condition that is frequently underdiagnosed or mistaken for other forms of vasculitis.

Which body systems are affected?

Livedoid vasculopathy primarily affects the skin, specifically on the lower extremities, including the ankles and the tops of the feet. Symptoms typically follow a progression:

• Initial stage: Small, red-purple spots or plaques appear on the skin.


• Ulceration: These spots break down into painful, shallow ulcers that can persist for weeks or months.


• Scarring: As they heal, they leave behind characteristic, porcelain-white, depressed scars called atrophie blanche, often surrounded by a red or purple rim.

Who is typically affected by Livedoid vasculopathy?

Livedoid vasculopathy most commonly affects women, with a female-to-male ratio of approximately 3:1. The average age of onset is typically between 30 and 50 years old, though it can occur at any age. The condition is often exacerbated by prolonged standing or heat, and many patients report that symptoms worsen during the summer months.

How is Livedoid vasculopathy different from other conditions?

Unlike systemic vasculitis, Livedoid vasculopathy is generally confined to the skin and does not usually involve internal organs. Physicians differentiate it from other conditions by the absence of systemic inflammation markers and by the specific appearance of the atrophie blanche scars. A skin biopsy is often the gold standard to confirm the diagnosis by revealing hyalinized vessel walls without true vasculitis (vessel wall inflammation).

Next steps

• Consult with a board-certified dermatologist who specializes in vascular skin disorders.


• Keep a symptom diary to track triggers, such as heat or extended periods of standing.


• Join the DiseaseMaps.org community to connect with other patients and share experiences.


• Ask your physician about potential underlying clotting disorders, as Livedoid vasculopathy is sometimes associated with hypercoagulable states.
