Case Report: An Uncommon Presenting Complaint of GPA
Granulomatosis with polyangiitis (GPA) is a small vessel vasculitis associated with anti-neutrophil cytoplasmic antibodies (C-ANCA), specifically proteinase 3 (PR3) ANCA. GPA classically presents with multi-organ involvement. The first description of GPA defined a triad of features: 1) systemic necrotizing angiitis, 2) necrotizing inflammation of the respiratory tract and 3) necrotizing glomerulonephritis.1 Few cases of digital…

Case Report: Migratory Polyarthritis as the Presenting Symptom of GPA
Granulomatosis with polyangiitis (GPA) is a primary, necrotizing granulomatous vasculitis, involving small- to medium-sized arteries, that causes systemic disease. Almost any organ can be affected, but the most affected systems are the upper airways, lungs, kidneys, eyes and peripheral nerves. Migratory polyarthritis is reported in approximately 25% of patients with anti-neutrophil cytoplasmic antibody (ANCA) associated…
Case Report: GPA or IgG4-Related Disease in an 11-Year-Old Girl?
Granulomatosis with polyangiitis (GPA) is a type of anti-neutrophil cytoplasmic antibody (ANCA) associated small vessel vasculitis that typically affects the kidneys, lungs and sinuses.1 Due to an overlap in signs and symptoms, GPA may initially be difficult to distinguish from IgG4-related disease, another condition that can affect multiple tissues and has variable presentations. Further complicating…
