ABSTRACT
Primary osteosarcoma of the skull is a rare finding. We report here on a pathologically proven case of osteosarcoma that presented as a painless mass in the frontal bone of a 7-year-old boy. This unusual form of osteosarcoma had features of desmoplastic fibroma in a large portion of the tumor. We also include a review of the medical literature related to osteosarcoma.
