Osteoblastoclastoma Malignant

Osteobastoislatosis is a tumor formation that arises from cells similar to bone tissue. It is not associated with metastasis and does not lead to damage to other organs, therefore it is considered a benign tumor. Osteoblastoiditis is a rare and quite aggressive disease. It is believed that in some cases the formation is malignant, in which case it is called osteoblastolitis, which is due to the presence of cancer cells in the structure of the tumor. This is rare, but in most cases, malignant cells are found in isolated areas of tissue. Benign and malignant tumors differ in the structure of tissue elements.

Ostebolato and lastoma have a similar appearance and cause similar symptoms. They are dense and hard growths in the bones of the skull, pelvis or trunk that can be painful and often lead to decreased movement and decreased quality of life. However, malignant tumors are more aggressive and can spread beyond the bone. This can lead to metastases in other parts of the body and the development of complications such as anemia, pain and dysfunction of vital organs and systems. Therefore, if you observe neoplasms in yourself, be sure to consult a doctor for diagnosis and treatment.



Osteosarcoma are malignant bone tumors. Most often, the bones of the skull and pelvis or the tubular bones of the extremities are affected, especially in the area of ​​the metaphyses.

Osteogenic bone sarcomas occur at any age, but predominantly in males. By the end of the second decade of life, osteosarcomas are detected twice as often as in other age groups. There are two types of sarcomas in children: the most common is osteogenic metaplastic tumor (about 80% of cases) and the less common is osteoblastosarcoma.

Etiology

Malignant tumors arise only in bones that have formed after the process of their formation is completed. Bones that remain incomplete (for example, the phalanges of the fingers and toes in children) cannot be a substrate for the development of a tumor. The source of the tumor can only be the compact substance of the bone and only in a small number of patients - its spongy part. In 70-80% of cases, the diagnosis is made in adults over 50 years of age, which is associated with more frequent injuries in young people. Bone is also the site of synthesis of substances responsible for its growth, and influences the development of the tumor, therefore the formation of a malignant bone tumor is called intramedullary, or intraosseous. The tumor can grow both symmetrically from the inside of the bone (exophytic type of growth), and symmetrically or atypically from the outside, peeling off the interosseous membrane with the formation of an exo- or endo-deposit of tumor cells in the surrounding soft tissues. The combination of some of the risk factors with trauma and previous therapy with hormonal drugs contributes to the recurrence of a malignant tumor of bone marrow origin. To localize and evaluate the tumor, the WHO classification system (1973) is used: 1. Endosta
