The need to distinguish true primary systemic vasculitis from its multiple potential mimickers is one of the most challenging diagnostic conundrums in clinical medicine. This article reviews 9 challenging vasculitis…
The diagnosis of large-vessel vasculitis has experienced substantial improvement in recent years. While Takayasu arteritis diagnosis relies on imaging, the involvement of epicranial arteries by giant-cell arteritis facilitates histopathological confirmation….
The major manifestations of antiphospholipid syndrome (APS) are caused by thrombosis within the venous or arterial vasculature, whereas the vascular lesions in systemic vasculitis result from an inflammatory infiltrate in…
Cryoglobulins are immunoglobulins that precipitate at temperatures less than 37°C. They occur secondary to infectious, autoimmune, and malignant processes. In the Brouet classification, type I cryoglobulinemia is caused by hyperviscosity,…
Cogan and Behcet syndromes are considered large vessel vasculitides. Both are rare diseases, with varied clinical manifestations affecting multiple organ systems. Although both have hallmark symptoms (ocular and vestibuloauditory inflammation…
Polyarteritis nodosa (PAN) is a systemic disease, but variants are cutaneous PAN and single-organ disease. Histologic confirmation of vasculitis in medium-sized arteries is desirable, and biopsies should be obtained from…
Kawasaki disease (KD) is the archetypal pediatric vasculitis, exemplifying the unique aspects and challenges of vascular inflammation in children. The condition is almost unheard of in adults, is closely associated…
Primary angiitis of the central nervous system (PACNS) is a rare disease, although it is increasingly recognized both in adults and children. Little is known about pathogenesis, but efforts at…
Small vessel vasculitis in the skin manifests with palpable purpura on the lower extremities. This clinical presentation prompts a complete physical examination, history, and review of systems, as well as…
This article provides an update on the diagnosis and management of the antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides, granulomatosis with polyangiitis (formerly Wegener), microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis (formerly…
