A 76-year-old female presented with a firm, non-tender mass that had grown gradually over the past year. This AP radiograph of the lower leg shows a bone-forming soft tissue lesion laying in the anterior compartment of the lower leg just anterior to the fibula. The zonal pattern suggests a soft tissue osteosarcoma because the mature, calcific portion of the lesion is centrally located as opposed to a myositis ossificans lesion where the mature ossification is seen at the periphery of the lesion. This was proven on biopsy to be an osteogenic sarcoma.
