Polyarteritis nodosa and allied conditions
Polyarteritis nodosa
- form of necrotizing vasculitis involving small- and medium-sized arteries; signs and symptoms result from infarction and scarring of the affected organ system.
Acute febrile mucocutaneous lymph node syndrome (mcls)
- systemic disease primarily of infants and young children, characterized by skin rash, swelling of hands and feet, enlarged cervical lymph nodes, "strawberry tongue", dry and cracked lips, high fevers, and coronary artery disease.
Hypersensitivity angiitis
Hypersensitivity angiitis unspecified
Goodpasture's syndrome
- combination of pulmonary hemorrhage and glomerulonephritis; known also as the lung purpura glomerulonephritis complex; considered by some to be a form of hypersensitivity reaction.
Other specified hypersensitivity angiitis
Lethal midline granuloma
- An aggressive, progressive, and destructive lesion affecting the nasal cavities, paranasal sinuses, and the palate. The vast majority of cases are malignant lymphoproliferations affecting the midline of the face in patients with nasal type extranodal NK/T-cell lymphoma.
Wegener's granulomatosis
- multisystem disease chiefly affecting males, characterized by necrotizing granulomatous vasculitis involving the upper and lower respiratory tracts, glomerulonephritis, and variable degrees of systemic small vessel vasculitis; considered an aberrant hypersensitivity reaction to an unknown antigen.
Giant cell arteritis
- subacute, granulomatous arteritis involving the external carotid arteries, especially the temporal artery; occurs in elderly persons and may be manifested by constitutional symptoms, particularly severe headache, and sometimes sudden unilateral blindness; shares many of the symptoms of polymyalgia rheumatica.
Thrombotic microangiopathy
- The syndromes of microangiopathic hemolytic anemia, thrombocytopenia, and variable signs of organ impairment, due to platelet aggregation in the microcirculation.
