Vasculitis - allergic hypersensitivity; Cutaneous Leukocytoclastic Vasculitis

• skin lesions usually located on legs, buttocks, or trunk
• palpable (able to be felt with the fingers) purpura
  • multiple papules (small, solid, raised skin areas)
  • purpura (bleeding into the skin)
• blisters on the skin
• urticaria (hives), may last longer than 24 hours
• necrotic ulcers (open sores with dead tissue)

The diagnosis is primarily based on a history of skin lesions that develop after exposure to medications or a foreign substance (antigen ) and the pattern of symptoms.

• The ESR (sed rate) may be elevated.
• Skin biopsy shows vasculitis (inflammation of the blood vessels).
