A 79-year-old man with metastatic melanoma of the right maxillary sinus and multiple liver metastases received a single dose of nivolumab. Eight days later, he experienced impaired consciousness, accompanied by abnormal laboratory and electrocardiographic findings. He was therefore diagnosed with tumor lysis syndrome (TLS). Laboratory and electrocardiographic findings improved immediately after continuous hemodiafiltration; however, he died 22 days after receiving nivolumab. Autopsy revealed massive tumor necrosis in the liver. There are few case reports of TLS associated with immune checkpoint inhibitors, indicating that we should be prepared to manage especially in a patient with liver involvement of high tumor burden.
