I need to know about the pathology of leukocytoclastic vasculitis. This must be an extremely rare form of the disease, because there is hardly any information about leukocytoclastic vasculitis on the internet! My medical encyclopaedia doesn't even include leukocytoclastic vasculitis! Let's change that and get some info up on this thread. Can you please start by telling me how leukocytoclastic vasculitis progresses?
