Periosteal chondrosarcoma

Introduction

Introduction to periosteal chondroma Periosteal chondrosarcoma is a rare subtype that is classified into one class because of its unique anatomical and histological features, and because its prognosis is better than central chondrosarcoma. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: skin chondroma

Cause

Cause of periosteal chondrosarcoma

Cause:

The cause of this disease is not fully understood, and some scholars believe that it may be related to genetics, trauma, nutrition and other factors.

Prevention

Periosteal 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

Periosteal chondrosarcoma complications Complications skin chondroma

Compression of nerves, blood vessels, late dysfunction, lymphatic vessels, and hematogenous metastasis.

Symptom

Periosteal chondrosarcoma symptoms Common symptoms Hip lateral swelling and tenderness Lower extremity swelling and fatigue Upper limbs suddenly appear swelling, soreness, bone pain, soft tissue swelling

Sex and age are similar to central chondrosarcoma. They are located at the metaphysis or end of the long bone. They occur in the femur, tibia and fibula, and rarely occur in short or flat bone. The symptoms are mainly swelling with mild pain or No pain.

Examine

Examination of periosteal chondrosarcoma

X-ray examination showed a spherical mass, sometimes uneven surface, located on the surface of the cortical bone, possibly originating from periosteum or periosteum, similar to cortical osteosarcoma. When periosteal chondroma is located at the distal end of the femur, it is often located behind the bone. And to the axillary development, periosteal chondrosarcoma showed cartilage mass, sometimes not on the X-ray film, can only be defined by CT or MRI examination, the tumor often has granular, point and ring calcification, Occasionally there is a blurred bundle of ossification, the cortical bone under the tumor is sometimes intact, sometimes the surface is eroded, the erosion of the cortical bone can be blurred, but often the butterfly-shaped impression, the boundary is clear and thick, around the tumor There may be a periosteal reaction that produces a triangular ossification that partially surrounds the tumor base.

Diagnosis

Diagnosis and diagnosis of periosteal chondrosarcoma

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

Need to be differentiated from periosteal chondroma, in the image, periosteal chondrosarcoma is more swell, eroding cortical bone, does not invade the medullary cavity, but the most important identification is histological identification, it should be noted that mild in periosteal chondroma The abnormality represents benign lesions and does not represent malignant lesions, especially in childhood. Therefore, the diagnosis of grade I periosteal chondrosarcoma may be wrong. Periosteal chondrosarcoma needs to be differentiated from adjacent cortical osteosarcoma. Osteosarcoma invades the diaphysis and appears as a needle-shaped, impervious X-ray image perpendicular to the cortical bone in imaging. Although there are a large number of chondrocytes in histology, it can be seen as a tumor-forming osteogenesis.
