Abstract

Purpose

The study goal was to clarify the association between computed tomography (CT) findings, histologic features, and outcome of osteosarcoma of the jaw (OSJ).

Materials and methods

The CT findings and histologic features of 10 patients with OSJ were retrospectively analyzed. The patients were histopathologically diagnosed to have OSJ. The points analyzed on the CT included the patterns of osteogenesis and any signs of bone destruction. The histologic types were classified according to the 1993 World Health Organization histologic classification of bone tumors. Furthermore, the histologic subtype was classified into the following 3 types: osteoblastic, chondroblastic, and fibroblastic. The grade of the tumor tissue was classified from I to IV. These were compared with the affected jaw site and the outcome of the patients with OSJ.
