In 1992, the Chapel Hill Consensus Conference on the Nomenclature of Systemic Vasculitis adopted the term microscopic polyangiitis to connote a necrotizing vasculitis with few or no immune complexes affecting small vessels (capillaries, venules, or arterioles). Glomerulonephritis is very common in microscopic polyangiitis, and pulmonary capillaritis often occurs. The absence of granulomatous inflammation in microscopic polyangiitis is said to differentiate it from granulomatosis with polyangiitis (Wegener’s).
