title: The aid of electron microscopy in the diagnosis of osteosarcoma of the bone (case report).
abstract: Osteogenic sarcoma with marked cellular anaplasia and little or no osteoid formation may present major problems in histologic identification. The application of electron microscopy is demonstrated in a case of a poorly differentiated osteosarcoma of the tibia. Unequivocal electron microscopic diagnostic findings are described in relation to light microscopic data.
