Acute tumor lysis syndrome in high grade lymphoblastic lymphoma after a prolonged episode of fever.

Acute tumor lysis syndrome occurs in rapidly growing lymphoid malignancies, usually as a consequence of chemotherapy or corticosteroids. We present what appears to be the first reported case of tumor lysis occurring after a sustained episode of high fever of 42.0 degrees C in a patient with high grade lymphoblastic lymphoma and a high tumor burden.
