BACKGROUND: The growing teratoma syndrome (GTS) consists of a mature teratoma paradoxically enlarging during or after chemotherapy for malignant nongerminomatous germ cell tumors. METHODS AND RESULTS: We report two cases of GTS occurring in association with NSGCT of the pineal gland. Although an unusual event, clinicians and radiologists should be aware of its natural history. CONCLUSIONS: When normalized tumor markers after chemotherapy are associated with imaging features of a growing mass, the hypothesis of GTS must be taken in consideration. When early diagnosed, GTS can be managed surgically with good results. PMID: 20878531 [PubMed - indexed for MEDLINE]
