Environmentally triggered small vessel vasculitis.
Ten randomly selected patients with recurrent non-specific small vessel vasculitis (edema, petechiae, spontaneous bruising, peripheral cyanosis) were studied under rigid environmental control. All cleared their symptoms without medications. All patients had their vasculitis reproduced after direct challenge with numerous individual foods and chemicals. Multiple incitants were found in each patient.
