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.
