MeSH

Inflammation of any one of the blood vessels, including the ARTERIES; VEINS; and rest of the vasculature system in the body.

Year introduced: 1978

Necrotizing VASCULITIS of small and medium size vessels, developing as a complication in RHEUMATOID ARTHRITIS patients. It is characterized by peripheral vascular lesions, cutaneous ULCERS, peripheral GANGRENE, and MONONEURITIS MULTIPLEX.

Year introduced: 2010

Group of systemic vasculitis with a strong association with ANCA. The disorders are characterized by necrotizing inflammation of small and medium size vessels, with little or no immune-complex deposits in vessel walls.

Year introduced: 2010

A heterogeneous group of diseases characterized by inflammation and necrosis of the blood vessel walls.

Year introduced: 2010

Inflammation of the retinal vasculature with various causes including infectious disease; LUPUS ERYTHEMATOSUS, SYSTEMIC; MULTIPLE SCLEROSIS; BEHCET SYNDROME; and CHORIORETINITIS.

Year introduced: 2003

Central nervous system vasculitis that is associated with SYSTEMIC LUPUS ERYTHEMATOSUS. Clinical manifestations may include DEMENTIA; SEIZURES; CRANIAL NERVE DISEASES; HEMIPARESIS; BLINDNESS; DYSPHASIA; and other neurological disorders.

Year introduced: 2000

Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)

Year introduced: 2000

Disorder characterized by a vasculitic syndrome associated with exposure to an antigen such as a drug, infectious agent, or other foreign or endogenous substance. Its pathophysiology includes immune complex deposition and a wide range of skin lesions. Hypersensitivity or allergy is present in some but not all cases.

Year introduced: 2010 (1995)

A systemic non-thrombocytopenic purpura caused by HYPERSENSITIVITY VASCULITIS and deposition of IGA-containing IMMUNE COMPLEXES within the blood vessels throughout the body, including those in the kidney (KIDNEY GLOMERULUS). Clinical symptoms include URTICARIA; ERYTHEMA; ARTHRITIS; GASTROINTESTINAL HEMORRHAGE; and renal involvement. Most cases are seen in children after acute upper respiratory infections.

Year introduced: 2022(1975)

Inflammation of ARTERIES in the CENTRAL NERVOUS SYSTEM that occurs in patients with ACQUIRED IMMUNODEFICIENCY SYNDROME or AIDS-RELATED OPPORTUNISTIC INFECTIONS.

Year introduced: 2000

Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from POLYARTERITIS NODOSA.

Year introduced: 1989

A rare cutaneous thrombotic disease due to occlusion of dermal vessels. It is characterized by purpuric maculae and ulcerations especially during summer which form scars called atrophie blanche. It is more associated with other syndromes (e.g., PROTEIN C DEFICIENCY; HYPERHOMOCYSTEINEMIA). Livedo reticularis with systemic involvement and stroke is SNEDDON SYNDROME.

Year introduced: 2022

Skin diseases affecting or involving the cutaneous blood vessels and generally manifested as inflammation, swelling, erythema, or necrosis in the affected area.

Year introduced: 1993

Date introduced: September 12, 2022

Date introduced: November 5, 2012

Date introduced: November 5, 2012

A rare type of leukocytoclastic vasculitis characterized by red, purple, brown, or yellow papules, plaques, or nodules usually on the extensor surfaces of the body. It is often associated with STREPTOCOCCAL INFECTIONS; HIV INFECTIONS; and HEPATITIS B.
