Fulminant Primary Manifestations Of Wegener'S Granulomatosis Might Not Be Pauci-Immune

Wegener's granulomatosis is an ANCA-associated small vessel vasculitis. Because histologically immune complex deposits are frequently lacking, the term pauci-immune has been introduced for this subgroup. We report a patient with fulminant, severe PR3-ANCA-positive Wegener's granulomatosis and multi-organ involvement (upper respiratory tract, lung, kidneys, skin and general symptoms), who showed pronounced immunoglobulin and complement deposits within the skin biopsy. Our observation supports the hypothesis that immune complex deposits may be under-recognized in early lesions of ANCA-associated Wegener's granulomatosis.
