Thoracic bone tumor

Introduction to chest wall bone tumor Thoracic wall tumors account for 7% to 8% of whole body bone tumors. Most chest wall tumors are malignant, 85% to 90% occur in ribs, and 10% to 15% occur in the sternum, with a male to female ratio of 2:1. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: chest wall soft tissue tumor

Chest wall bone tumor cause

Causes

A chest wall tumor is a tumor that occurs in deep tissues of the thorax, including tumors of bone, periosteum, muscle, blood vessels, nerves, etc., but does not include skin, subcutaneous tissue, and breast tumors. The chest wall tumors are divided into two major categories: primary and secondary. The primary tumors are divided into benign and malignant. Primary benign tumors include lipoma, fibroids, neurofibroma, schwannomas, bone fibrous dysplasia, osteofibroma, chondroma, osteochondroma and bone cysts; primary malignant tumors with fibrosarcoma, nerve Fibrosarcoma, angiosarcoma, rhabdomyosarcoma, chondrosarcoma, osteosarcoma, osteochondroma and malignant giant cell tumor are common. Secondary chest wall tumors are almost all metastasized from malignant tumors in other parts, often causing local destruction of ribs or pathological fractures, causing pain, but local lumps are not obvious, mainly metastatic cancer.

Chest wall bone tumor prevention

At present, there is no relevant information, mainly paying attention to some details of life in life.

Chest wall bone tumor complications Complications chest wall soft tissue tumor

Chest pain, infection.

Chest wall bone tumor symptoms common symptoms chest pain

The slowly increasing chest wall mass, 20% to 25% asymptomatic, eventually causes chest pain, and chest pain is more common in malignant bone tumors.

Examination of chest wall bone tumor

Chest radiograph, chest fluoroscopy, chest MRI, chest CT examination, tumor radioimmunoimaging (RII).

Diagnosis and diagnosis of chest wall tumor

According to the bone tumor biopsy.

1. Open biopsy: The purpose is to remove the biopsy of lesions with higher likelihood of benign, preferably with pathology, radiologist consultation, excision biopsy is very suitable for malignant diseases, operation methods: longitudinal incision; sharp separation to direct tumor, To pass through the muscle tissue, do not walk between the muscles; the unaffected anatomical space should not be revealed; avoid all large vascular nerves to avoid contamination; the whole piece of resected tissue, pseudo-envelope, capsule and whole tumor, Use formalin to fix or send frozen; bone wounds should be as small as possible to avoid infection; wounds should be strictly hemostasis; effective wound drainage; if the resection is continued after biopsy, the instruments should be replaced.

2. Needle biopsy: still an open biopsy, the biopsy path should be within the resectable range.

Fine needle biopsy:

1 relying on the cytological analysis of experienced pathologists;

2 accuracy rate is 65% to 95% (depending on the amount of specimen collected);

3 can not do immunohistochemical analysis.

Core needle biopsy:

1 is a stamping card structure, the outer sleeve encloses the needle core, and the tissue specimen is grasped;

2 more needles can get more samples, can do immunohistochemical analysis;

3 accuracy rate is 75% to 95%.

The unfavorable factors of needle aspiration biopsy are: the tumor necrosis site may be worn, so the diagnosis cannot be made, or the tissue taken may be the reaction tissue around the tumor, which cannot represent the actual tumor. Relatively speaking, the frozen section is not These shortcomings.

3. Frozen section: If the specimen is sufficient and is the diseased tissue, the diagnosis can be confirmed; if the lesion is inflammation, it needs to be cultured; it can be confirmed whether further examination is needed; rapid diagnosis can be made to determine further treatment (surgery).

Imaging studies can identify chest wall tumors and lung tumors, and MRI can be used to distinguish soft tissue tumors from vascular lesions.
