ABSTRACT
Growing teratoma syndrome (GTS) is documented in literature to be a rare complication of non-seminomatous germ cell tumors that arises following chemotherapeutic treatment. Though represented through multiple case reports, the condition is rare that it evades observation and diagnosis, leading to complications secondary to metastasis and unchecked growth. GTS is identified via incidental finding on imaging (e.g. CT) or due to complications involving mass obstruction. Due to the potential severity of undiagnosed malignancy, it is important to effectively diagnose GTS in those presenting with non-specific symptoms and a history of testicular/ovarian cancer. It is also necessary to develop a method on how to monitor those considered to be at increased risk for developing such a condition. Here, we present a case of a middle-aged male who presented with complaints of a left lower quadrant abdominal mass and incidental finding of right retroperitoneal lesion, consistent with GTS.
