Idiopathic Adult Onset Fanconi’s Syndrome in a Patient Treated with Oxaliplatin

Abstract

Proximal tubular injury is known complication of chemotherapy such as carboplatin. However, there are far more other causes of injury and in many situations, the etiology is difficult to elucidate. Here we describe a case of a patient who presented with a urine analysis consistent of Fanconi’s syndrome with signs and symptoms of the disorder prior to chemotherapy but requiring admission for aggressive electrolyte replacement soon after the chemotherapy was completed. We further discuss causes of Fanconi’s syndrome and the importance of evaluation of the proximal convoluted tubule prior to administration of chemotherapy.
