Radiography, pathology and the treatment result in the patient's first presentation with tibial intra-cortical osteosarcoma. (a) Anteroposterior radiograph of the right tibia indicating an intra-cortical lytic bone lesion. (b) Longitudinal section of the en bloc histological specimen demonstrating a well-circumscribed intra-cortical mass enclosed by periosteum. (c) A tissue histological specimen (first episode) shows a tumor consisting of small nests and cords of cells (arrow) surrounded by thick anastomosing branches of osteoid without any chondrosarcomatous or fibrosarcomatous matrix (hematoxylin and eosin stain; original magnification, ×400). (d) The tibia was reconstructed by using an Ilizarov external fixator for bone transportation. (e) Radiographs showing the patient's tibia six months after Ilizarov removal (two years after bone resection). (f) Good functional activity of the patient's knee and ankle was shown after treatment.
