[Clinicopathological study of osteosarcoma of the jaw]

Eighty-five cases of osteosarcoma of the jaw were analyzed for clinical and histologic characters. According to the predominant histologic differentiation of the tumor, it was divided into osteoblastic, chondroblastic and fibroblastic type. Chondroblastic osteosarcoma was associated with the worst survival rate. The histologic grade was closely related to the prognosis of tumor.
