A case of tumor of the spinal cord with a long clinical history was described. At autopsy, the tumor was composed of a mixture of two elemental cells, i.e. matured but neoplastic ganglionic cells and anaplastic glial cells. The clinical manifestations suggested that the tumor in this case developed in a benign form with malignant evolution occurring during the latter part of its clinical course. The malignant evolution, however, was due to aggressive and anaplastic growth only of the elemental glial cells, while the cytologic features of the elemental ganglionic cells remained always benign.
描述了一例具有较长临床病史的脊髓肿瘤病例。尸检时，肿瘤由两种基本细胞混合组成，即成熟但呈肿瘤性的神经节细胞和间变性神经胶质细胞。临床表现提示该病例中的肿瘤以良性形式发展，在临床病程后期发生恶性演变。然而，恶性演变仅归因于基本神经胶质细胞的侵袭性和间变性生长，而基本神经节细胞的细胞学特征始终保持良性。
