rheumatic vasculitis
Introduction
Introduction Rheumatoid vasculitis: a common systemic connective tissue disease characterized by non-suppurative polyarthritis. If extra-articular manifestations are the main clinical symptoms, such as pleurisy, myocarditis, pneumonia, neuritis and vasculitis, it is called malignant rheumatoid arthritis. Vasculitis is one of the basic pathologies of rheumatoid arthritis. Its various vascular lesions, most without symptoms, are only found at autopsy, so there is generally no clinical significance, but if multiple blood vessels occur (including medium arteries, small When the arteries and capillaries are inflammatory occlusion, the symptoms are obvious and even fatal, which is generally called rheumatoid vasculitis.

Clinical manifestations of cutaneous vasculitis damage, limited access to purpura, non-specific erythema of the trunk, vascular infarction, bullae and ulcers, 20% of patients with finger (toe) gangrene. Capillary vasodilation, infarct papules and nodules occur in nail folds. Histopathological manifestations of leukocyte fragmentation vasculitis, also seen lymphocytic necrosis vasculitis. Invasion of blood vessels is different, and the condition is different. Intensive invading small and medium arteries has extensive systemic damage. Systemic signs and symptoms have moderate fever, fatigue, myalgia, joint pain, abdominal pain and/or gastrointestinal bleeding, pleurisy or pulmonary infiltration, pericarditis, mild proteinuria and hematuria, retinal hemorrhage, and central or peripheral nervous system Affected.
Diagnosis
Differential diagnosis
1. Skin-type nodular polyarteritis is mostly in the lower limbs, there are subcutaneous nodules distributed along the small arteries, conscious pain and obvious tenderness, skin histopathological manifestations of arteritis and small arterial necrosis.
2. It should also be differentiated from hyperglobulinemia, acute acne-like lichen-like pityriasis and nodular vasculitis.
