Differential diagnosis of chondrosarcoma in the following areas:
Differential diagnosis of a chondrosarcoma. Mesenchymal chondrosarcoma tumor cells in the tumor consistent with a small round mesenchymal cells, tumor tissue contains the more mature chondrocytes Island. Poorly differentiated tumor cells of chondrosarcoma polymorphism and dysplasia of the more obvious, and well-differentiated chondrosarcoma tissues do not contain large areas of undifferentiated mesenchymal tumor cells, it is not difficult to identify.
Differential diagnosis of chondrosarcoma 2. Osteosarcoma osteosarcoma more cartilage components, were identified to be, and chondrosarcoma. Incidence of osteosarcoma younger, mostly in adolescence, rapid growth, easy to early transfer, the tumor cells directly into bone tissue or bone tumor; and chondrosarcoma late onset, slow growth, late stage can be transferred, the bone of bone lesions are cartilaginous. If the tumor on imaging or central part of the main part of the tumor showed calcification of cartilage and bone when the edge of the visible tumor to the possibility of a large chondrosarcoma; In addition, less periosteal reaction chondrosarcoma.
3 Differential diagnosis of chondrosarcoma. Chondroma differentiated chondroma chondrosarcoma must identify, in benign and malignant tumor of the judgments about, in the long bones, axial skeleton, the scapula and pelvis, etc. of chondrosarcoma, especially in the larger, Even if benign imaging findings should be seen as low-grade, located in the hand, foot and the bone tumors were benign, rarely malignant. Based mainly on identification of abnormal cells and whether the infiltration of the host.
