C-ANCA Positive Vasculitis in a Case of Amyloidosis

Case report An unusual presentation of C-ANCA vasculitis

A 54-year-old woman presented to casualty with left arm weakness, having had a preceding transient ischaemic episode in the same area and generalized flu-like symptoms a few days before admission. She had no traditional risk factors for vascular disease other than being an ex-smoker.

Diffuse Alveolar Hemorrhage in IgA Vasculitis with an Atypical Presentation

IgA vasculitis (IgAV) commonly occurs in young children, who present with a tetrad of purpura, abdominal pain, arthralgia and nephritis. Diffuse alveolar hemorrhage (DAH) is a rare complication of IgAV. We herein report an adult case of IgAV with a presentation of DAH and nephritis (pulmonary renal syndrome, PRS), but without other typical manifestations, such as purpura, abdominal pain and art...

Lung vasculitis and alveolar hemorrhage: pathology.

Pulmonary vasculitides are a diverse group of limited and systemic disorders associated with inflammation of pulmonary vessels and parenchyma. These diseases often have distinctive clinical, serological, and histopathological features-extrapulmonary sites of involvement, circulating autoantibodies, predispositions for small or large vessels, and others. Some have characteristic inflammatory les...

Alveolar hemorrhage in vasculitis: primary and secondary.

Diffuse alveolar hemorrhage (DAH) in primary and secondary vasculitis occurs when capillaritis is present. The diagnosis of DAH is considered in patients who develop progressive dyspnea with alveolar opacities on chest imaging (with density ranging from ground glass to consolidation) that cannot be explained otherwise. Hemoptysis, a valuable sign, is often absent. A decline of blood hemoglobin ...
