Bevacizumab-Induced Nephropathy Presenting as Crescentic Glomerulopathy

Bevacizumab-induced nephropathy is a common adverse event observed in patients who receive chemotherapy. These patients usually present with hypertension and nephrotic range proteinuria. Thrombotic microangiopathy is the characteristic histologic pattern of bevacizumab-induced nephropathy. However, a few cases reported IgA vasculitis with nephritis as an unusual pattern. In this case report, we describe a patient diagnosed with bevacizumab-induced nephropathy with a distinctive histologic pattern demonstrating focal proliferative crescentic glomerulonephritis with polyclonal immune complex deposition.
