Granulomatous polyangiitis, formerly called Wegener's granulomatosis, is a vasculitis of medium and small arteries, including venules and arterioles. It produces granulomatous inflammation of the respiratory tracts and necrotizing, pauci-immune glomerulonephritis.
While it is considered a rare disease (3 cases per 100,000 people in the U.S.),[1] Wegener's is the most common cause of saddle nose deformity in USA (nose flattened due to destruction of nasal septum by granulomatous inflammation). It also has a high mortality rate if untreated.
Diagnosis
Almost all patients with Wegener's have the c-ANCA form of antineutrophil cytoplasmic antibodies, but not vice versa.
