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.en10.1097/MPH.0b013e3181d4181cinfo:eu-repo/semantics/openAccessChildrenGerm Cell TumorMalignant TransformationNeuroblastomaSacrococcygeal Mature Cystic TeratomaArticle32323323520387262Q3WOS:000276667800008Q3
