Bevacizumab-induced immunoglobulin A vasculitis with nephritis: A case report

Rationale: Bevacizumab—an inhibitor of vascular endothelial growth factor—is effective against various advanced cancers. However, it is associated with the development of hypertension and high-grade proteinuria during thrombotic microangiopathy of the kidney. In addition, there are several reports of immunoglobulin A deposition in the glomeruli, but the etiology is unclear.
