Systemic Vasculitis Mimics Pancreatic Tumor

Segmental arterial mediolysis mimics systemic vasculitis.

Segmental arterial mediolysis (SAM) is a rare, nonarteriosclerotic, noninflammatory vascular disease and mostly affects medium-to-large sized abdominal arteries as well as presents with hemorrhages in the abdominal cavity. We report the case of a patient with SAM of the celiac, right renal, jejunal branch of the superior mesenteric, left gastric, and splenic arteries who was diagnosed by exclud...

Systemic vasculitis.

The systemic vasculitides are characterized by inflammation of blood vessel walls. Vessels of any type, in any organ can be affected, resulting in a broad spectrum of signs and symptoms. The heterogenous nature of vasculitides presents a diagnostic challenge. The American College of Rheumatology classification criteria and the Chapel Hill Consensus Conference nomenclature are the most widely us...

Cardiac tumor-like mass in a patient with systemic vasculitis.

Leukocytoclastic vasculitis: another condition that mimics syphilis.

Syphilis, a disease that in the past was associated with significant morbidity and lethality rates, has resurged in recent years principally as a consequence of changes in risk behavior. An epidemiological group that is commonly affected is the HIV-infected population. The characteristics of the disease and its progression may differ in these patients. The present report describes a case of an ...

Autoantibodies in Systemic Vasculitis

Systemic vasculitis is a heterogeneous group of disorders characterized by inflammation andnecrosis in the vessel wall. The diagnosis of a systemic vasculitis is challenging, because patients usually present a broad spectrum of manifestations that vary according to the predominant size of vessels affected, organs and systems involved, and the extent of the inflammatory process (1). In systemic ...
