Resumen

Introduction: Growing teratoma syndrome (GTS) is characterized by tumor enlargement during or after chemotherapy for non-seminomatous germ cell tumors, accompanied by the normalization of previously elevated tumor marker levels and the presence of mature teratoma components in histological examination. Clinical case: We present the case of a 25-year-old man diagnosed with a mixed germ cell tumor. The patient underwent surgery and chemotherapy; however, one year later, he was diagnosed with GTS due to the presence of a retroperitoneal mass that did not respond to a second chemotherapy regimen.
