Overview
Granulomatosis with polyangiitis must be differentiated from other diseases that cause purpura, alveolar hemorrhage, fever, arthralgia, myalgia, necrotizing extra-capillary glomerulonephritis, such as Microscopic polyangiitis and Eosinophilic granulomatosis with polyangiitis.[1]
Differentiating Granulomatosis with polyangiits from other Diseases
Granulomatosis with polyangiitis must be differentiated from other diseases that cause purpura, alveolar hemorrhage, necrotizing extra-capillary glomerulonephritis, such as Microscopic polyangiitis and Eosinophilic granulomatosis with polyangiitis.[1] [2]

Differentiating Granulomatosis with polyangiitis from other Diseases
Granulomatosis with polyangiitis must be differentiated from other diseases that cause purpura, alveolar hemorrhage, fever, arthralgia, myalgia, necrotizing extra-capillary glomerulonephritis and include:[1]
- mononeuritis multiplex
- venous thrombosis
- necrotizing vasculitis of small-sized vessels
- ear nose throat involvement
