The clinical manifestations of urticarial vasculitis are windmills of varying sizes, which remain pigmented after fading, usually with pain and burning sensation, often accompanied by fever, arthritis, arthralgia, abdominal discomfort, and so on.
Urticarial vasculitis is associated with immune complex deposition, and is most common in middle-aged women. The lesions are urticaria-like wheals, but they last longer, usually more than 24 hours, and are often painful and burning rather than itchy, and are often accompanied by irregular fever at the time of onset and hyperpigmentation when they subside, so they need to be differentiated from urticaria.
The disease is often accompanied by fever, arthritis, arthralgia, abdominal discomfort, enlarged lymph nodes and kidney involvement, and is often an early symptom of diseases such as dermatomyositis and systemic lupus erythematosus.
If you are suffering from urticarial vasculitis, it is recommended that you consult a doctor as soon as possible for systematic treatment to avoid delays.
