Clear cell chondrosarcoma

Introduction to clear cell chondrosarcoma Clear cell chondrosarcoma is a rare subtype that is somewhat similar to chondroblastoma and has a malignancy between grade I and II central chondrosarcoma. Located in the epiphysis or bone convex, occurs in the proximal femur, proximal humerus, flat bone and short bone. basic knowledge Sickness ratio: 0.0001% Susceptible people: no specific population Mode of infection: non-infectious Complications: chondrosarcoma periosteal chondroma

Clear cell chondrosarcoma etiology

1. Seen by the naked eye: The tumor is soft, is a fuzzy cartilage-like substance, sometimes has a bone-like substance, which can be granular, and the tumor is often red or bloody.

2. Seen under the microscope: the tumor is leafy, the nucleus of the transparent cell is slightly centered, the cytoplasm is rich and transparent, the PAS staining is strong positive, the pleomorphism is obvious, the mitosis is rare, and the cell is more than the periphery of the leaf. Reactive multinucleated giant cells can be seen. Differently differentiated chondrosarcoma cells can be seen between these cells, which are equivalent to grade I to II chondrosarcoma. Sometimes there may be calcification between cells (like in chondroblastoma), sometimes visible. Bone products (reactive), sometimes these can be in the cytosol.

Clear cell chondrosarcoma prevention

It is a malignant chondroma, which is a type that occurs in adults. It is also rare, has a low degree of malignancy, and has a better prognosis than other chondrosarcomas.

Clear cell chondrosarcoma complications Complications chondrosarcoma periosteal sarcoma

Complications include joint pain, limited joint fluid and joint activity.

Clear cell chondrosarcoma symptoms common symptoms joint effusion joint deformity joint pain shoulder joint activity limitation

Gender and age are similar to chondrosarcoma, located in the epiphysis or bulge, occurring in the proximal femur, proximal humerus, flat bone and short bone, clinically often characterized by joint pain, joint effusion and joint mobility.

Examination of clear cell chondrosarcoma

X-ray findings are similar to those of chondroblastoma that occur in the epiphysis. It appears (at least in the early stage) that there is a clear boundary osteolytic area, but the lesion can recur after curettage. If not treated, it appears to have Quite invasive, X-ray calcification is visible in the tumor, and the tumor grows slowly or very slowly.

Diagnosis and diagnosis of clear cell chondrosarcoma

Clinically, it needs to be differentiated from aneurysmal cyst, benign chondroblastoma, osteoblastoma, highly malignant clear cell osteosarcoma, and metastatic clear cell carcinoma.
