title: [Chondrosarcoma of the vertebral column L5--S1].
abstract: A case of chondrosarcoma of the spine in a 15-year-old female patient has been described. The tumor was localized within the body of S1 and it partially involved the left wing of the ilium. The radiological condition corresponded with the so-called "ivory vertebra". The symptoms of compression of the cauda equina took the lead. Surgical decompression of the cauda equina was performed and an attempt of resection of the tumor was undertaken but it failed because of extension of the process. The further course of the disease, in spite of radiotherapy, was exceptionally malignant and within several months, the process became generalized.
