Malignant transformation of a germ cell tumor, referring to the occurrence of somatic, nongerm cell malignancy within a germ cell tumor is a rare entity. The authors report a case of malignant transformation of an unreseceted sacrococcygeal teratoma to neuroblastoma in a 6-year-old girl and discuss this case in the light of relevant literature. This case shows that complete resection of germ cell tumor is necessary to prevent malignant transformation; In addition, when malignant transformation occurs, the treatment strategy must include surgery together with histology adapted systemic chemotherapy.
