Inflammation of a blood vessel or a lymph vessel. Also known as angiitis.



inflammation of the walls of the small blood vessels. Vasculitis is usually caused by influenza, typhus, streptococcal infections (erysipelas, angina), or physical factors (frostbite, burns). Vasculitis may also arise as a secondary manifestation of collagen or allergic diseases, such as rheumatism, lupus erythematosus, rheumatoid arthritis, and serum and drug diseases. Sometimes vasculitis may be caused by a combination of some of these factors. The most usual, and often the only, external symptom of vasculitis is affection of the skin (hemorrhages, rashes, necrotic nidi, and so forth). As vasculitis progresses, thrombi may form in the vessels (thrombovasculitis), necrosis of the walls of the vessels may occur, and aneurysms may form. In the final stage of vasculitis complete occlusion of the vessels by a thrombus may occur, which leads to the disrupting of nutrition to the corresponding tissues and organs, bursting of aneurysms, and hemorrhaging into the surrounding tissues. Vasculitis is classified according to site as cutaneous and visceral; the latter predominantly affects the vessels of serous and mucous membranes of internal organs, such as the liver and kidneys. Treatment consists of the removal of the main disease causing the vasculitis.

In particular, rheumatoid arthritis, Sjoumlren syndrome and lupus erythematosus may have an associated hypersensitivity vasculitis. So as far as RD is concerned he is not yet off the hook from CTD, but I hope it is not CTD as the presence of vasculitis in connective tissue disease like lupus often denotes active disease and possibly a poorer prognosis.

(8) Drug induced hypersensitivity vasculitis typically involves small vessels and its pathologic mechanisms include T-cell recognition of proteins or deposition of immune complexes in blood-vessel walls.
Cutaneous leukocytoclastic angiitisis (hypersensitivity vasculitis) is a clinical term that generally refers to an Immune Complex-mediated small vessel vasculitis of the skin that spares internal organs and usually follows drug exposures or infections.
