A 72-year-old male gave a history of prostate cancer that was treated with local radiation therapy three years before. The man had also undergone a total hip replacement for osteoarthritis. He had developed recent symptoms of pain in the hip that were progressive over the past three months. This AP radiograph shows neoplastic activity in the para-acetabular area and posterior column of the hip extending down into the ischium with lytic changes as well as blastic activity within the ischium. Biopsy proved the biopsy of osteosarcoma arising in the area of previous radiation therapy.
