Systemic disease characterized by formation of hyalinized and thickened collagenous fibrous tissue, with thickening of the skin and adhesion to underlying tissues (especially of the hands and face), dysphagia due to loss of peristalsis and submucosal fibrosis of the esophagus, dyspnea due to pulmonary fibrosis, myocardial fibrosis, and renal vascular changes resembling those of malignant hypertension.
Term for diseases that involve inflammation of and damage to blood vessels. May affect different-sized blood vessels, and affect skin and internal organs. Includes diseases such as giant cell arteritis, Churg-Strauss syndrome, Kawasaki disease, Takayasu’s arteritis, and polyarteritis nodosa. Symptoms may include a severe rash called palpable purpura, neuropathy, or signs of lung and kidney problems, such as coughing up blood. Other symptoms may occur, including joint pain, fatigue, fever, weakness, or abdominal pain. Necrotizing vasculitis occurs when inflammation causes thickening and scarring of blood vessel walls, damaging tissues and cutting off blood supply. This can cause visible symptoms like raised skin lesions or fingers turning blue. Glucocorticoids and immunosuppressants may help treat systemic vasculitis.
