One of the main areas of revision included the description of 2 pathophysiologically different groups of small vessel vasculitis including immune complex vasculitis and AAV (Table 1).

Immune complex vasculitis usually has a largely dependent distribution, and the pauci-immune variety has a random distribution.
In vasculitic purpura, it's important to determine the variety of immune complex vasculitis, because IgA-associated vasculitis is more likely than IgG- or IgM-predominant vasculitis to persist, recur, ulcerate, and be associated with systemic disease, he said.
A dependent distribution suggests immune complex vasculitis.
