Soft tissue tumors with the characteristics of Ewing sarcoma of bone have thus far only been studied by light microscopy. A pelvic tumor of this type in a 13-year-old girl was examined by electron microscopy. Comparison of its ultrastructural features with those of reported cases of bony Ewing sarcoma reveal much similarity. It is believed that they are probably identical and that the tumor cells are of immature mesenchymal type. However, their site of origin and the direction of their potential differentiation remain obscure.
迄今为止，具有骨尤文肉瘤特征的软组织肿瘤仅通过光学显微镜进行过研究。对一名13岁女孩的盆腔此类肿瘤进行了电子显微镜检查。将其超微结构特征与已报道的骨尤文肉瘤病例相比较，发现有许多相似之处。据信它们可能是相同的，且肿瘤细胞为未成熟间充质类型。然而，它们的起源部位及其可能的分化方向仍不清楚。
