Abstract
Mixed germ cell tumors (GCT) with teratoma components can transform into somatic malignancies which can include histologiesoutside of traditional germ cell lineages. We describe a case of an 18-year-old man with a metastatic testicular GCT with bothmature and immature teratoma components containing malignant transformation into multiple histologies including PNET inthe primary testicular tumor and osteosarcoma in a separate pulmonary metastatic lesion. Management with targetedchemotherapy resulted in a durable remission. This is thefirst reported case that we know of a patient with primary PNETmalignant transformation with subsequent metastatic transformation to osteosarcoma
