A cadaveric kidney transplant recipient, with no history of a connective tissue disease, was admitted with malaise, arthralgias, diplopia, mild headache, and a painful left eye. The patient was on maintenance immunosuppression for 14 years with cyclosporine and methylprednisolone. Initial laboratory data indicated an elevated serum creatinine from baseline, 2+ proteinuria, and 50 to 100 red blood cells (RBCs)/high-power field (HPF) in the urine. Renal biopsy was consistent with necrotizing vasculitis involving glomerular capillaries, with crescent formation and an absence of immune complexes. Perinuclear antineutrophil cytoplasmic autoantibodies (P-ANCA) and anti-myeloperoxidase (MPO) were found to be elevated. To the best of our knowledge, this is the first reported case of an ANCA-associated small vessel vasculitis (SVV) developing in a renal transplant recipient without history of connective tissue disease.
