Cutaneous Vasculitis (skin vasculitis)

Symptoms

The symptoms of cutaneous vasculitis vary depending on the severity and location of the blood vessel inflammation. Common symptoms include:

• Red or purple spots on the skin, usually on the legs
• Swelling and pain around the affected areas
• Itching or a burning sensation
• Blisters or skin ulcers in severe cases
• General malaise such as fever or fatigue

These symptoms can appear suddenly and vary in intensity.

Causes
The exact cause of cutaneous vasculitis is often unknown, but the condition can be associated with:

• The immune system attacking the blood vessel walls, which sometimes occurs after an infection, the use of certain medications, or as part of another disease such as lupus or rheumatoid arthritis
• Genetic factors, although the precise role of genetics is still being investigated
• Exposure to certain external factors such as infections or allergens that can trigger an inflammatory response

Diagnosis
The diagnosis of cutaneous vasculitis is usually made by a dermatologist based on:

• A physical examination of the skin
• A detailed medical history
• Blood tests to detect inflammation and possible underlying conditions
• Skin biopsy of an affected area to examine the nature of the inflammation and the involved blood vessels

Treatment
The treatment of cutaneous vasculitis focuses on relieving the symptoms and, if possible, treating the underlying cause. Treatment methods include:

• Anti-inflammatory medication such as corticosteroids to reduce inflammation
• Medication to suppress the immune system if the vasculitis is caused by an autoimmune disease
• Treatment of any underlying infections
• In severe cases, medication to improve blood flow and prevent further damage to the blood vessels

Self-care tips
Some self-care tips to manage symptoms include:

• Protect the skin from injuries and extreme temperatures
• Wear comfortable, non-restrictive clothing
• Use skincare products to minimize irritation
• Adopt a healthy lifestyle with regular exercise and a balanced diet
• Avoid known triggers such as certain medications or foods if these have been identified
