• 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)

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.
