Allergic vasculitis

Definition

Allergic vasculitis is an extreme reaction to a drug, infection, or foreign substance that leads to inflammation and damage to blood vessels of the skin.

Alternative Names

Vasculitis - allergic; Hypersensitivity vasculitis; Cutaneous leukocytoclastic vasculitis

Causes, incidence, and risk factors

Allergic vasculitis is caused by an allergic reaction to a drug or other foreign substance. Most patients are older than 15 years.

Even with a thorough history, the cause of this condition cannot be identified.

Symptoms

  • Purple-colored spots and patches
  • Skin lesions usually located on the legs, buttocks, or trunk
  • Blisters on the skin
  • Hives (urticaria), may last longer than 24 hours
  • Open sores with dead tissue (necrotic ulcers)

Signs and tests

The diagnosis is based on your symptoms and how the skin looks after you take a certain medicine or are exposed to a foreign substance (antigen).

Results from an ESR test may be high. Skin biopsy shows inflammation of the blood vessels.

Treatment

The goal of treatment is to reduce inflammation.

Your health care provider may prescribe aspirin or corticosteroids to reduce inflammation of the blood vessels. (DO NOT give aspirin to children except as advised by your health care provider.)

If possible, your doctor may tell you to stop taking the medicine that caused this condition. Do not stop taking any medicine without first talking to your doctor.

Expectations (prognosis)

Allergic vasculitis usually goes away over time. On occasion, people will have repeated episodes.

Complications

  • Permanent damage to the blood vessels or skin with scarring
  • Inflammation of the blood vessels affects the internal organs

Calling your health care provider

Call for an appointment with your health care provider if you have symptoms of allergic vasculitis.

Prevention

Avoid exposure to medications to which you have known allergies.
