Targeting the vascular endothelial growth factor (VEGF) signaling pathway has become an important approach to current cancer therapy. Anti-VEGF therapy-related renal adverse effects may present as hypertension, non-nephrotic proteinuria, and rarely as nephrotic syndrome (NS) and acute kidney injury.In this report, we present a 15-year-old boy who had developed nephrotic syndrome and thrombotic microangiopathy 26 months after administration of anti-VEGF therapy. Treatment was discontinued and nephrotic syndrome remitted spontaneously within 3 months.Nephrologists should be aware of the side effects of anti-VEGF therapy. Early diagnosis and prompt management with withdrawal of the agents will result in spontaneous remission.
