Two cases of chordoma of the sacrococcygeal region have been histochemically evaluated. In both cases an irregularly shaped stellate cell, containing large amounts of glycogen, is the prevailing cell type. Neoplastic cells interact with an extracellular matrix consisting of a collagenous framework and a heterogeneous family of glycosaminoglycans with a prevalence of chondroitin sulfate chains and, to a smaller extent, of hyaluronate molecules. We emphasize the value of these data in order to differentiate this tumor from other sacrococcygeal neoplastic lesions.
对两例骶尾骨区域脊索瘤进行了组织化学评估。在这两例病例中，主要的细胞类型是形状不规则的星状细胞，含有大量糖原。肿瘤细胞与由胶原框架和一组异质性糖胺聚糖组成的细胞外基质相互作用，其中硫酸软骨素链占优势，透明质酸分子含量较少。我们强调这些数据对于将该肿瘤与其他骶尾骨肿瘤性病变相鉴别的价值。
