title: Extraskeletal myxoid chondrosarcoma with multiple skeletal metastases.
abstract: Pulmonary metastases are not unusual in extraskeletal myxoid chondrosarcoma; however, only two patients have been reported with multiple bony metastases. We report here one patient with extraskeletal myxoid chondrosarcoma associated with lung and multiple bony metastases. After chemotherapy, the primary lesion was resected, but lung and multiple bony metastases were found 20 months later. The bony metastases were in the right femur, right humerus, and at multiple vertebral levels. Because of a pathologic fracture of the right femur, the metastases in the right femur and right humerus were surgically stabilized. After chemotherapy, the lung metastases were resected, and those in the vertebral bodies were treated with radiotherapy.
