[Osteosarcoma: 2d malignant tumor following treatment with radiotherapy].
The authors report a case of postirradiation osteosarcoma that appeared in a seven year old girl after having received radiation therapy for a soft tissue sarcoma. The latent period between the two malignancies was 5 and a half years and the apparently radiation-induced osteosarcoma developed within the radiation field of the primary tumor.
