title: Primary tumours in the spine and pelvis in adolescents: clinical and radiological features.
abstract: In 34 patients in their two first decades of life with primary bone tumours in the spine and pelvis, the most common benign tumour was histiocytosis X and the most common malignant tumour, Ewing's sarcoma. X-rays were positive in 32 out of 34 cases but of little diagnostic value and primary complaints were without significance. The final diagnosis can only be made after a biopsy.
