Discussion Vasculitis is inflammation of the blood vessels. The primary event initiating inflammation may be an abnormality of the blood, the vessel wall, or the tissues adjacent to the vessel. Small blood vessels with slow rates of flow are usually affected. The stagnant circulation in the capillaries and venules of the legs make these common sites for vasculitis.
Vasculitis can affect all organs.
The kidneys, lungs, and joints are often affected in addition to skin. Investigation showed no evidence of a bacterial endocarditis. The British National Formulary indicated that some ACE inhibitors cause a symptom complex which include fever, arthralgia, myalgia ,and vasculitis. Therefore his ACE inhibitor was discontinued. Within 24 hours his temperature had settled, and at 4 weeks' review in outpatients his vasculitis had completely resolved.
