A case of cerebellar medullomyoblastoma in a young boy was investigated by electron microscopy. The neuroectodermal component shows the characteristics of a desmoplastic medulloblastoma. The mesodermal component consists of more or less differentiated cross-striated muscle cells. Undifferentiated muscle cells are very similar to proliferated endothelial cells of blood vessels within the muscular component, so that an origin of this component from pluripotential endothelial cells of the vessel wall is suggested. This tumor is considered a malignant teratoid because of the derivation from two blastodermic layers and because of the midline localization in children suggesting a malformative origin.
一名小男孩的小脑髓母细胞瘤病例通过电子显微镜进行了研究。神经外胚层成分显示出促纤维增生性髓母细胞瘤的特征。中胚层成分由或多或少分化的横纹肌细胞组成。未分化的肌细胞与肌肉成分内血管增生的内皮细胞非常相似，因此提示该成分起源于血管壁的多能内皮细胞。由于该肿瘤起源于两个胚层且在儿童中位于中线提示有畸形起源，所以被认为是恶性畸胎瘤。
