A Rare Occurrence of Metastatic Gastric Adenocarcinoma Causing Acute Spontaneous Tumor Lysis Syndrome and Acute Renal Failure: A Case Report and Review of the Literature

Tumor lysis syndrome is an oncologic emergency. It is typically seen in malignancies with high tumor burden and is seen much more frequently in hematologic malignancies than in solid tumors. More often, tumor lysis syndrome occurs as a result of anti-cancer treatment, however it can also occur spontaneously. Here we present a rare case, to our knowledge only the third ever reported case, of metastatic gastric adenocarcinoma causing acute spontaneous tumor lysis syndrome.
