Exercise-induced vasculitis, CONSIDERED TO NE INNOCENT


What are the clinical features of exercise-induced vasculitis?

Exercise-induced vasculitis mainly affects one or both lower legs and thighs, with single or multiple episodes of a rash with the following characteristics:

  • Involvement of exposed skin and sparing of skin protected by socks or stockings
  • Red patches, urticarial lesions (weals) and purpura (purple spots)
  • Oedema (swelling) of the affected leg(s)
  • Intense itching, stinging, pain or burning

The patient is otherwise well, without fever, malaise or other symptoms.

Lesions resolve over 3 to 4 weeks. A purplish-brown mark may persist for longer.
