extraosseous chondrosarcoma
Introduction
Introduction of extra-osseous chondrosarcoma Extra-osseous chondrosarcoma is a chondrosarcoma of soft tissue, which can be divided into mucous type, mesenchymal type and differentiated type. Since the differentiation type is rare, only extramedicular mucinous chondroma is introduced here. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: anemia
Cause
Causes of extra-osseous chondrosarcoma
The etiology of this disease is not fully understood yet. It can be grown from the epiphyseal cartilage to the bone surface. It can also originate from the tympanic cell layer or the anterior cartilage fibrous tissue originating from the tendon attachment. In genetics, the abnormalities of chromosomes 8, 11, and 19 are abnormal. It has a certain relationship with the occurrence of osteochondroma.
Prevention
Extra-osseous chondrosarcoma prevention
There are no special and effective preventive measures, and some adjustments can be made in the diet:
1. Maintain an ideal weight.
2. Ingest a variety of foods.
3. The diet includes a variety of vegetables and fruits.
4. Ingest more high-fiber foods (such as whole grain cereals, beans, vegetables, and fruits).
5. Reduce total fat intake.
6. Limit the intake of alcoholic beverages.
7. Limit the intake of marinated, smoked, and nitrite-containing foods.
Complication
Extracorporeal chondrosarcoma complications Complications anemia
Late stage dysfunction, anemia, weight loss and other systemic symptoms.

1. Extramedullary mucinous chondrosarcoma occurs mostly in middle age, with an average age of about 50 years. Males are more than females. The thighs and knees are more common, generally in the deeper layers of the muscles.
2. Extramedullary mesenchymal soft sarcoma is a young woman aged 15 to 35 years old, more common in the head and neck, and the other limbs, the posterior peritoneum can also occur.
Examine
Examination of extra-osseous chondrosarcoma
Extramedullary mucinous chondrosarcoma
(1) The tumor seen by the naked eye is multi-nodular, with complete capsule, lobulated surface, viscose-like, bleeding, and cystic zone.
(2) The cells seen under the microscope are lobularly distributed. In the mucous matrix rich in the lobular leaves, the small tumor cells are arranged in a cord shape, and the chondrocytes are seen, the cells are eosinophilic and have vacuolar cells and small. Concentrate the cell nucleus.
Extramedullary mesenchymal soft sarcoma
(1) The tumor seen by the naked eye is large, multi-nodular, and the cut surface is grayish-white fish-like, and there may be scattered small cartilage-like tissue.
(2) The tumor seen under the microscope consists of undifferentiated mesenchymal cells. The cells are spindle-shaped, with thick nuclear staining and few cytoplasm. Differently differentiated island-like cartilage tissue can be seen, and the cartilage center can be calcified.
Diagnosis
Diagnosis and diagnosis of extra-chondral chondrosarcoma
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
1. Extramedullary mucinous chondrosarcoma should be differentiated from mucinous liposarcoma, mucinous malignant fibrous histiocytoma.
2. Extramedullary mesenchymal soft sarcoma should be differentiated from synovial sarcoma
