Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. [1]: 831 [2] The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, [3]
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.
Malaise, arthralgia, sinusitis, and rhinitis are typically present at the beginning of Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Prodromes often occur weeks or months before pulmonary-renal syndrome. [3] Anti-glomerular basement membrane (anti-GBM) vasculitis patients usually report sudden onset of anuria or oliguria.
[7] [14] Inflammation of the outer layers of the eye (scleritis and episcleritis [15] [16]) and conjunctivitis are the most common signs of GPA in the eye; involvement of the eyes is common and occurs in slightly more than half of people with the disease. [6] Kidney: rapidly progressive glomerulonephritis (75%), leading to chronic kidney disease
Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. [1] It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis, among others. [2]
For assessment of the morphological and functional aspects of microcirculation, nailfold videocapillaroscopy (NVC) can be used, in which videocapillaroscopy is performed at the nailfold, where capillaries are arranged with the longitudinal axis parallel to the skin surface, so that they can be examined along their entire length.

Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
