Explanation: Wegener granulomatosis is a necrotizing vasculitis characterized by a specific triad of findings: * Granulomas of the lung and/or the upper respiratory tract (ear, nose, sinuses, throat) * Vasculitis of small to medium-sized vessels (capillaries, venules, aerioles, and aeries), most prominently in the lungs and upper respiratory tract * Glomerulonephritis "Limited" forms of disease can be restricted to the respiratory tract. Conversely, a widespread form of the disease can affect eyes, skin, and other organs, notably the hea; clinically, this resembles polyaeritis nodosa with the additional feature of respiratory involvement.
