Livedo reticularis is a skin condition that appears as a bluish or purplish, net-like pattern on the skin. It is often found on the legs, arms, or trunk and worsens with cold. It is usually a harmless condition but can sometimes be a sign of an underlying medical issue. At Heights Dermatology, we would like to help you learn about and be aware of skin conditions like livedo reticularis in order to keep your skin healthy.
What Causes Livedo Reticularis?
Livedo reticularis is caused by abnormalities in the blood flow through the small blood vessels close to the skin's surface. When these blood vessels constrict or become blocked, the skin can become mottled or develop a lace-like appearance. Some of the potential causes of livedo reticularis are:
1. Temperature Sensitivity: Exposure to cold can trigger livedo reticularis in some individuals. This is called "physiologic livedo reticularis" and can resolve when the skin is warmed.
2. Vascular Conditions: Vascular conditions such as vasculitis or antiphospholipid syndrome can lead to more chronic forms of livedo reticularis.
3. Autoimmune Disorders: Conditions like rheumatoid arthritis or lupus can cause changes in blood flow that can result in livedo reticularis.
4. Medications: Certain medications that affect blood flow or clotting can result in the development of this skin pattern.
5. Blood Disorders: Some disorders such as overproduction of red blood cells or other clotting disorders can also be associated with livedo reticularis.
Symptoms of Livedo Reticularis
The primary symptom of livedo reticularis is a purple, net-like skin discoloration. The other symptoms are not constant and vary according to the underlying condition and may feature:
- Ongoing or persistent skin mottling
- Cold or numb sensation in the affected area
- Skin discoloration that does not improve with warmth
- Pain or ulcerations (severe cases linked with vascular diseases)
If you notice persistent or unusual changes in the skin, it is important to have a medical examination to rule out any underlying medical conditions.
