Synchronous Primary Multifocal Skeletal Chondrosarcoma of Extremity: A Report of 2 Cases.

ABSTRACT

CASE Multifocal synchronous primary skeletal chondrosarcomas of an extremity are rarely reported. In this study, we report 2 such cases. The first case is a 32-year-old woman who presented with extensive right femoral and tibial diaphysis lesions. The second case is a 36-year-old woman with lesions in the left proximal humerus, the coracoid process of scapula and sternum. Both patients underwent limb salvage surgery and were disease-free at the 38- and 20-month follow-up. CONCLUSION: Athough rare, the possibility of multifocal chondrosarcoma should be kept in mind during the workup of a patient with chondrosarcoma.
