[Sacrococcygeal tumours--diagnosis-treatment strategies based on personal examinations]

Sacrococcygeal tumours very often appear soon after birth when they are usually benign. In older children more frequently malignant tumours are observed. The authors present diagnostic and therapeutic strategy based on clinical material consisting of 34 patients (15 benign tumours, 19 malignant tumours) treated at the National Research Institute of Mother and Child in the period 1980-1999.
