Cutaneous vasculitis

Cutaneous vasculitis is a condition characterized by inflammation and damage to the blood vessels in the skin. This condition can be a primary condition, or it can be secondary to another disease or condition.

Symptoms

The symptoms of cutaneous vasculitis can vary depending on the severity of the condition. Common symptoms include:

• Rash: This is often the first symptom of cutaneous vasculitis. The rash can appear as red or purple spots or bumps on the skin.
• Pain: The affected areas of the skin may be painful.
• Itching: The rash may be itchy.
• Ulcers: In severe cases, ulcers can form on the skin.

Causes

The exact cause of cutaneous vasculitis is unknown. However, it is thought to be an autoimmune response, where the body's immune system mistakenly attacks the blood vessels in the skin. Certain factors may increase the risk of developing cutaneous vasculitis, including:

• Infections: Certain infections, such as hepatitis C, can trigger cutaneous vasculitis.
• Medications: Some medications, including certain antibiotics and nonsteroidal anti-inflammatory drugs, can cause cutaneous vasculitis.
• Autoimmune diseases: People with autoimmune diseases, such as lupus or rheumatoid arthritis, are at a higher risk of developing cutaneous vasculitis.

Diagnosis

The diagnosis of cutaneous vasculitis is usually made based on the patient's symptoms and a physical examination. Additional tests may be needed to confirm the diagnosis and determine the severity of the condition, including:

• Skin biopsy: A small sample of skin is removed and examined under a microscope.
• Blood tests: These can help to identify any underlying conditions that may be causing the vasculitis.

Treatment

The treatment for cutaneous vasculitis depends on the severity of the condition and the underlying cause. Treatment options may include:

• Topical corticosteroids: These are creams or ointments that are applied to the skin to reduce inflammation.
• Oral corticosteroids: These are medications that are taken by mouth to reduce inflammation throughout the body.
• Immunosuppressive drugs: These are medications that suppress the immune system, reducing the autoimmune response that is causing the vasculitis.
