Sarcoma Osteogenic Ectopic

Osteogenic ectopic sarcoma (s. osteogenum ectopicum) is a malignant tumor that develops from mesenchymal precursor cells and is characterized by the production of tumor bone tissue. Ectopic osteosarcoma usually occurs in soft tissues such as muscle and subcutaneous fat rather than bone.

The main clinical manifestations include the appearance of a painful node in the soft tissues and local tumor growth. Histologically, the tumor consists of tumor cells that produce bone (osteoblasts) and immature bone tissue (osteoid). Diagnosis is based on the clinical picture, imaging (X-ray, CT, MRI) and histological examination of the biopsy material.

The main treatment method is surgical removal of the tumor. Often combined and complex treatment is carried out using radiation therapy and chemotherapy. The prognosis depends on the size, location and possibility of radical removal of the tumor. The overall prognosis is less favorable compared to osteosarcoma of the bone. Relapses and metastasis are possible.

S. osteogenium ectopic sarcoma is a rare type of bone tumor that develops at the junction of two bones or some distance from a bone. It can occur in both long bones and short bones. This disease can lead to serious complications, so it is necessary to promptly diagnose and treat ectopic osteogenic sarcoma.

Osteogenic sarcoma (OS) is a malignant tumor arising from connective tissue cells (chondrocytes), and osteogenic sarcoma is from bone tumors. Sarcomas of this type are quite rare cancerous bone tumors. They are characterized by rapid growth, invasion of adjacent tissues and the ability to metastasize, which increases the risk of death of the patient.

In most cases, OM occurs in long tubular bones – the bones of the limbs. Approximately 15% of tumors involve the bones of the lower and upper extremities, while the rest occur in the chest, sternum, collarbone, spine and sacrum, as well as in the flat bones of the pelvis.

The etiological factor of OM is radiation, radiation sickness or radiation during chemotherapy courses. In addition, OM can be caused by genetic mutations and defects in the immune system. There is an increased risk of cancer in people over 50, especially those who already have immune system diseases or have a family history of bone cancer. Women get sick more often than men.

Over time, CO increases in size, destroying surrounding tissues, and can become a threat to the patient's life. Treatment for OM should be started immediately. Treatment consists of surgical removal of the tumor, radiation and chemotherapy (depending on the stage of the disease and other factors). Surgery involves resection of the bone and removal of the affected tissue. It is important to consider that OM is resistant to chemotherapy and radiation can cause secondary lymphomas.
