Abstract
- Sarcoma is a malignant tumor originated from bone, cartilage, fat tissue, nerve, blood vessel, bone marrow, endothelium, etc. and for this reason it exhibits considerable variation not only clinical but histologic appearance. Osteosarcoma occurs chiefly in young persons and in patients older than 40 years it is usually associated with Paget's disease, irradiated bone, multiple hereditary exostosis or polyostotoc fibrous dysplasia and sometimes with preceding trauma. Radiographically it is divided into three forms: an osteoblastic or sclerosing type, an osteolytic type, and mixed type. Histologically it is divided into osteoblastic type, chondroblastic type, fibroblastic type. The treatment of osteosarcoma is radical excision, combined chemotherapy but the prognosis is poor and overall 5-year survival rate is 20-40%. We present two different type sarcomas of 22-year-old male and 56-year-old male patients which we performed surgical excision, combined chemotherapy and radiation therapy.
