title: The pathology of large-vessel vasculitides.
abstract: Vasculitis affecting large elastic arteries, including the aorta and major proximal branches, encompasses various diseases including Takayasu arteritis, giant cell (or temporal) arteritis, and tertiary syphilis, but also may occur as a rare complication of Behçet's disease, rheumatoid arthritis, sarcoidosis, Cogan syndrome, Kawasaki disease, ankylosing spondylitis, systemic lupus erythematosus and Wegener's granulomatosis. Recent reports have also established a link between inflammatory abdominal aortic aneurysm as well as lymphoplasmacytic thoracic aortitis with an overabundance of IgG4-producing plasma cells and the burgeoning constellation of 'Hyper-IgG4' syndromes. This review focuses on morphologic aspects of large-vessel vasculitis pathology associated with giant cell arteritis, Takayasu arteritis, idiopathic or isolated aortitis, lymphoplasmacytic thoracic and ascending aortitis, and the inflammatory aneurysm/retroperitoneal fibrosis syndrome.
