Malignant bone tumours in pregnancy (a report of two cases and review of literature).

Two cases of malignant bone tumours in pregnancy are reported. The optimum management is not clearly defined due to the rarity of the condition and limited individual experience. Our patients delivered healthy babies without any signs of maternal malignant disease. Cancer chemotherapy was instituted during the postmortem period. Pregnancy did not appear to exacerbate the tumour growth nor in any way affect the ultimate outcome of the patients.
