[A case of vertebral chondroblastoma].

The authors have observed a case of cervical chondroblastoma in a child aged nine years. Clinically there was a mediastinal syndrome, with pulmonary tract infection. Resection was achieved in two stages. One year later a local recurrence was treated by a third resection, followed by radiotherapy. Three years later there was no sign of recurrence. A review of the literature summarises the difficulties of diagnosis.
