title: Primary osteosarcoma of the skull.
abstract: In 33 cases of primary osteosarcoma of the skull in a relatively old age group, the sex ratio and poor prognosis is the same as in osteosarcoma of long bones. However, patients in the second decade of life free of neurologic disease have a better prognosis.
