title: [Clinical, radiological and pathological study of Ewing's sarcoma of the lumbar spine. Round cell sarcomas. Report on three cases (author's transl)].
abstract: Two cases of primary bone condensation type Ewing's sarcoma of a lumbar vertebra are described in children aged 8 and 10 years, as well as one case of the osteolytic form in a 14-year-old child. Ewing's sarcoma very rarely occurs in the spine, and the type with bone condensation is almost exclusively of a primary nature. The tumour extends simultaneously into the epidural space and the perispinal planes. Intravenous urography and myelography with metrizamide are therefore essential for evaluating the degree of tumour extension. Computed tomography examinations are also now necessary. Prognosis is bad and current therapeutic possibilities limited. Histological diagnosis is the only means of distinguishing Ewing's sarcoma from other round cell sarcomas in or around the spine.
