ABSTRACTWe describe the cases of three patients who developed a symmetrical purpuric rash on the legs, after long walks on hot days. Histological examination of one lesion showed signs of leukocytoclastic vasculitis without fibrinoid necrosis. The cases were diagnosed exercise-induced vasculitis. The treatment consisted in oral antihistamines and topical corticosteroids with favorable outcome. Exercise-induced vasculitis is a self-limiting process with good prognosis that can be differentiated from other forms of leukocytoclastic vasculitis.
