Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage.
Treatment should be directed towards the specific underlying cause of the vasculitis. If no underlying cause is found and the vasculitis is truly limited to the skin then treatment is primarily supportive. [13] Such treatment involves measures such as leg elevation, stockings, and topical steroids to relieve itching/burning.
Golfer's vasculitis, also called exercise-induced vasculitis, sport-induced vasculitis, Disney rash, or hiker's rash, is a form of small blood vessel inflammation resulting in a rash. [1] It occurs in the lower legs, and is caused by excessive walking in hot temperatures. It is more common in elderly people.
Necrotizing vasculitis, also called systemic necrotizing vasculitis, [1] is a general term for the inflammation of veins and arteries that develops into necrosis and narrows the vessels.

Livedoid vasculopathy (LV) is an uncommon thrombotic dermal vasculopathy that is characterized by excruciating, recurrent ulcers on the lower limbs. [4] Livedo racemosa, along with painful ulceration in the distal regions of the lower extremities, is the characteristic clinical appearance.
Henoch–Schönlein purpura is a small-vessel vasculitis in which complexes of immunoglobulin A (IgA) and complement component 3 (C3) are deposited on arterioles, capillaries, and venules (hence it is a type III hypersensitivity reaction).
Peripheral artery disease (PAD) is a vascular disorder that causes abnormal narrowing of arteries other than those that supply the heart or brain. [5] [15] PAD can happen in any blood vessel, but it is more common in the legs than the arms.
