The etiology of most malignant bone tumors is poorly understood, and most bone malignancies are believed to arise de novo. Nevertheless, a small number of malignant bone tumors arise in recognizable benign precursors, and these lesions may be may be divided into three conceptual categories: diseases with documented predisposition to malignant bone tumors; sporadic benign tumors with a known risk for secondary malignancy; and postradiation malignant tumors (Table 1). The following review attempts to summarize the more common entities in each category with an emphasis on clinical manifestations and pathological findings.
