Malignant bone tumors of the chest wall.

Malignant bone tumors constitute only 0.2% of all tumors. Bone sarcomas occur at a rate approximately one tenth that of sarcomas of the soft tissue. Malignant bone tumors of the chest wall and sternum are even more rare because most bone tumors occur in the long bones or joints. Because of the relative paucity of experience treating these malignancies, progress in successful therapies has been limited. Chondrosarcomas remain the most common bony malignant chest wall lesions and are discussed elsewhere in this issue. Other lesions in descending order of incidence include Ewing's sarcoma, osteosarcoma, malignant fibrous histiocytoma, solitary plasmacytoma, and Askin tumors. This article reviews these remaining five malignant bony chest wall tumors, along with their symptoms, presentations, and current approaches to therapy.
