The first report of postirradiation sarcoma was by Beck in 1922. Since then sarcoma arising in previously irradiated bone and soft tissue has been well recognized, but the incidence is low.We report a case of postirradiation osteosarcoma of sacrum. A fifty-eight-year old female was admitted to Kitakyushu Municipal Kokura Hospital in March 1985 because of severe sacral pain. In 1966, the patient underwent radical hysterectomy and radiation therapy for carcinoma of the cervix, after which she remained asymptomatic. In December 1984, she was admitted to Kokura Memorial Hospital for sacral pain. X-rays revealed massive osteoblastic changes of sacrum. Open biopsy was performed and the diagnosis of osteogenic sarcoma was established. Corresponding to Arlen's criteria, we thought this tumor was postirradiation osteosarcoma.
