Intracortical osteosarcoma.
A case of osteosarcoma arising in the tibia of a 15-year-old boy is reported. Of particular interest was the benign roentgenographic appearance and the confinement of the tumor within the cortex of the bone, an extremely rare phenomenon consistent with origin within the primitive mesenchyme of the Haversian canals.
