Abstract:
Objective To investigate the clinical presentations,pathological features and radiographic appearance of intraosseous well differentiated osteosarcoma and its differential diagnosis.Methods One case of intraosseous well differentiated osteosarcoma was analyzed,and the clinical presentations,radiographic appearances and histological features of intraosseous well differentiated osteosarcoma were summaried on the basis of reviewing the related literatures.Results The age of onset of this disease was mostly within a range of 30~40 years.The scopes of this lesion were almost large,and the metaphyses of the long bone were the major targets of the lesions,especially the inferior extremity of femur and superior extremity of tibia.The tumor appeared as destruction of combined with bony restoration within the medullary cavity.The tumor was composed of fiber and bony tissue which had well differentiated cells with rarely nuclear division.About 50 % of patients was diagnosed incorrectly as benign lesion at first.Conclusion It is difficult to early diagnose intraosseous well differentiated osteosarcoma,but comprehending its pathological,immunohistological features and combining clinic will benefit for the correct diagnosis.
