Many of the vasculitides (conditions associated with vasculitis) have a cutaneous component. In all cases a thorough work-up is required to investigate for an underlying cause and/or associated systemic features Differential diagnosis includes other vasculitic disorders that affect small- and medium-sized vessels. Infections, especially those due to slow-growing fungi or acid-fast organisms, should be ruled out by staining and culture of the sampled tissues

Rheumatoid vasculitis (RV) is a rare complication of rheumatoid arthritis (RA). RV usually occurs in the setting of prolonged severe RA with high rheumatoid factor (RF) titers, typically over a decade after the initial diagnosis of RA. Disease incidence has decreased from approximately 5% to 1%, most likely due to improvements in the clinical. Polyarteritis nodosa (PAN) is a systemic necrotizing inflammation of blood vessels (vasculitis) affecting medium-sized muscular arteries, typically involving the arteries of the kidneys and other internal organs but generally sparing the lungs' circulation.

Francès The main differential diagnosis of infectious necrotizing granulomas is granulomatosis with polyangiitis (Wegener's granulomatosis). The key distinguishing feature is the presence of a true necrotizing vasculitis. • A subset of necrotizing granulomas will not have an identifiable aetiology histologically or clinically.

Cutaneous vasculitis and their differential diagnose

Wegener's granulomatosis (WG) is a multisystemic vasculitis, with skin involvement in 14% of cases and with palpable purpura, subcutaneous nodules and necrotic papules as the common features. (1) We present a patient diagnosed with WG who had multiple whitish papules similar to those of malignant atrophic papulosis (Degos' disease), which. Figure 2 illustrates the differential diagnosis of ANCA and non-ANCA-associated vasculitis. About 10 percent of patients with microscopic polyangiitis (the most common type of ANCA-associated small vessel vasculitis) and Wegener's granulomatosis have negative assays for ANCA; however, this finding does not completely rule out these. The differential diagnosis for LCV is extensive. A skin biopsy will largely aid in the diagnosis. Other small vessel vasculitis: Immunoglobulin A vasculitis (formerly Henoch-Schönlein purpura) - Acute onset of palpable purpura usually seen in children aged younger than 10 years in the lower extremities / buttocks 1-2 weeks after a. Demonstration of necrotising vasculitis and granulomatous inflammation on tissue biopsy can confirm the diagnosis in the appropriate clinical setting. The differential diagnosis of GPA varies significantly with the pattern, extent, and severity of organ involvement. Risk factors. There is no gender predominance Diagnosis History. An accurate history is important as it will heavily guide the differential diagnosis for AF. The age of the patient and the past medical history (e.g., vasculopathic risk factors, history of migraines, cardiac or valvular disease, vasculitis) are important predisposing considerations

Wegener's is a collagen vascular disease with vasculitis involving the lung, kidney and sinuses. In the lung the vasculitis causes infarcts which first present as ill-defined areas of consolidation.
