Managing growing teratoma syndrome: new insights and clinical applications

Although a recognized condition, growing teratoma syndrome (GTS) has no guidelines for management, and patients diagnosed with the condition are managed empirically by the most appropriate teams. We report a case of GTS in a 33-year-old patient who was initially treated with unilateral salpingo-oophorectomy and subsequent chemotherapy for a germ cell ovarian tumor. GTS was subsequently diagnosed with massive pelvic and upper abdominal masses as well as lung tumors. We also conducted a literature review on cases of GTS presenting with large tumors. Based on this, we suggest a management plan to guide the care of women with GTS. The condition is best managed in a multidisciplinary team involving the relevant surgeons, including gynecologist, abdominal and thoracic surgeons.
