sarcoma
Introduction
Introduction to sarcoma Malignant tumors derived from mesenchymal tissue (including connective tissue and muscle) are called "sarcomas", which occur mostly at the skin, subcutaneous, periosteum and long bones. For example, fibrosarcoma grows rapidly, and there are often necrosis, hemorrhage, and cut gray in the late stage of the tumor. Red, uniform and fine as raw fish. Osteosarcoma is more common in young people, and it occurs at the two ends of the long bones of the extremities, especially at the lower end of the femur, the upper end of the humerus and the upper end of the tibia. Osteosarcoma develops rapidly and has a short course of disease. It begins to grow in the cortex and can gradually develop into the medullary cavity. Sometimes it breaks through the periosteum and invades the surrounding soft tissue. It is easy to cause pathological fractures. Commonly, leiomyomas, lymphosarcoma, and synovium In sarcoma, blood transfer can occur early. Sarcoma is a malignant tumor. basic knowledge The proportion of illness: 1% Susceptible people: no special people Mode of infection: non-infectious complication:
Cause
Sarcoma cause
(1) Causes of the disease
The cause is still unknown.
(two) pathogenesis
The pathogenesis is still unclear.
Prevention
Sarcoma prevention
There is no effective preventive measure for this disease. Early detection and early treatment are the key to prevention.
Complication
Sarcoma complications Complication
Physical pain, joint pain, low fever, fatigue, skin flushing and swelling.
Symptom
Symptoms of sarcoma Common symptoms Low heat, low heat, fatigue
Local symptoms: local pain and swelling or accompanied by localized skin redness, hot joint effusion, pain or restriction of limb or joint activity.
Systemic symptoms: low heat and fatigue, discomfort, and dysfunction of related parts.
Examine
Sarcoma examination
X-ray examination, CT scan, MRI (magnetic resonance examination), bone scan can be used for preliminary diagnosis of various sarcomas, and if necessary, puncture and tissue biopsy should be performed to confirm the diagnosis.
Some patients may have anemia and neutrophilia, and erythrocyte sedimentation rate may increase. Serum alkaline phosphate and lactate dehydrogenase may be elevated in patients with osteosarcoma and Ewing's sarcoma. Chondrosarcoma may have abnormal glucose tolerance test.

Differential diagnosis
It should be differentiated from fibrosarcoma or malignant fibrous histiocytoma, Ewing sarcoma.
