Tumor lysis syndrome from a solitary nonseminomatous germ cell tumor

Abstract

Spontaneous tumor lysis syndrome is a rare clinical entity, which typically occurs in the context of rapidly proliferating hematologic malignancies. Tumor lysis syndrome in solid organ malignancies is even rarer, and typically provoked by cytotoxic treatment regimens. We describe a case of spontaneous tumor lysis of a solitary metastatic brain lesion from a nonseminomatous germ cell tumor. This case is unique in that spontaneous tumor lysis from a brain metastasis of a solid organ malignancy has never been reported, and spontaneous tumor lysis in a nonseminomatous germ cell tumor is exceedingly rare.
