Vasculitis (plural: vasculitides) is a group of disorders that destroy blood vessels by inflammation. Both arteries and veins are affected. Lymphangitis is sometimes considered a type of vasculitis. Vasculitis is primarily caused by leukocyte migration and resultant damage.Although both occur in vasculitis inflammation of veins (phlebitis) or arteries (arteritis) on their own are separate entities.
