Osteoblastosarcoma

Osteoblastosarcoma: symptoms, diagnosis, treatment

Osteoblastosarcoma is a rare type of malignant tumor that occurs in the bones. This tumor comes from osteoblasts, which are the cells responsible for the formation of bone tissue. Osteoblastosarcoma usually affects large bones, such as the hip or upper arm, and most often occurs in teenagers and young adults.

Symptoms of osteoblastosarcoma may include pain in the area of ​​the affected bone, swelling, limited movement, and weakness in the limb. ABOUT

Osteoblastosarcoma: description Osteoblastosarcoma (osteol sarcea) is a rare malignant tumor of osteogenic cells originating from bone tissue. The majority of morbidity cases occur in people over 30 years of age. It occurs in different parts of the body - from the skull to the skin, subcutaneous tissue, organs and bone fractures. Most often, the disease occurs in a highly differentiated manner, less often in a poorly differentiated manner, in the area of ​​long tubular bones.

Clinically, the disease makes itself felt by the gradual development of a tumor with an increase in not only the subcutaneous part, but also the bone surfaces themselves, which leads to disruption of normal processes in bone tissue and its compaction. Upon external examination, redness corresponding to the tumor, the formation of erosions and pits (in the bone tissue) are visible. The resulting pathological inclusions significantly interfere with patients' walking, and some of them do not support body weight well and cause bone formation in the joints and bedsores. Patients develop osteoporosis and the structure of the tubular elements is disrupted. It is possible that the size of the abdomen may increase due to the accumulation of fluid in the abdomen. A tumor can form either against the background of a normal state or remain relatively stable for a long time. In case of degeneration into sarcomatoid tissue, the prognosis sharply worsens - about 50% of patients die within 2 years from the moment of diagnosis.
