摘要
Eight cases of mesenchymal chondrosarcoma either of skeletal(5 cases) or extrasketetalorigin (3 cases) are reported. According to histopathological and diagnostic criteria,mesenchymal chondrosarcoma were classified into two types cartilage isiand cell type andundifierentiated small cell type It is believed that the application of this classification in the study ofmesenchymal chondrosarcoma is helptul the estimation of its malignancy and choice of treatmentas well al in the prediction of its prognosis. Mesenchymal chondrosarcoma is a highly malignant neoplasm with poor prognosis. None ofthe patients in this series survived more than five years after they were diagnosed. The diffentialdiagnosis of malignant lymphoma, chondrosarcoma, hemangiopericytosarcoma, etc. was discussed.My data support the assumption that mesenchymal chondrosarcoma originates from the secondarymesenchyme rather than the primary mesenchyme.
