Tumor lysis syndrome developing intraoperatively

Tumor lysis syndrome is a potentially life threatening condition which is most commonly encountered in patients being treated with chemotherapy. We report a case of spontaneous tumor lysis syndrome that developed intraoperatively in a patient with undiagnosed Burkitt's lymphoma. Characteristic electrolyte disturbances and white emulsion like urine following laparotomy and tumor handling intraoperatively suggested the diagnosis. This is a rare perioperative complication and the report emphasizes the importance of being vigilant in recognizing the same.
