Spontaneous tumor lysis syndrome in a patient with cholangiocarcinoma.
Tumor lysis syndrome (TLS) is a potentially deadly complication of tumors or their treatment. This syndrome consists of a constellation of laboratory parameters such as hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia and clinical complications such as seizures, acute renal insult, cardiac dysrhythmias and death. TLS is especially common in patients with hematological malignancies with rapid cellular turnover rates such as acute lymphocytic leukemia and Burkitt lymphoma, but is very rare in patients with solid tumors. However, it is essential to keep in mind that solid tumors can also lead to TLS. We present a case of a 66-year-old African American male with metastatic cholangiocarcinoma complicated by the development of spontaneous TLS. TLS has never been reported in a patient with cholangiocarcinoma.
