原始神经外胚层肿瘤(primitive neuroectodermal tumor,PNET)是一种少见的神经嵴衍生小圆细胞恶性肿瘤[1],主要由原始神经上皮组成,可伴有多向分化潜能,因原始神经外胚层肿瘤与尤文肉瘤(EWS)具有相似的遗传背景和基因改
Primitive neuroectodermal tumor (PNET) is a rare malignant tumor derived from neural crest [1], mainly composed of primitive neuroepithelial epithelial cells, which may be associated with the potential of multidirectional differentiation due to primitive neuroectodermal tumors And Ewing’s sarcoma (EWS) has a similar genetic background and genetically modified
