Types of bone tumors
The doctrine of bone tumors is one of the least developed sections of Clinical Oncology. In the literature, there are no accurate statistics on the incidence and mortality from cancer tumors of bones.
According to the international histological classification, the following types of primary tumors and tumor-like bone diseases:
Bone forming tumors
Benign
- Osteoma
- Osteoid osteoma
- Osteoblastoma (Benign osteoblastoma)
Malignant
- Osteosarcoma (osteosarcoma)
- Periosteal osteosarcoma yukstakortikalnaya (parostalnaya sarcoma)
Hryascheobrazuyuschie tumor
Benign
- Xondroma
- Osteoxondroma (osteochondral exostosis)
- Xondroʙlastoma (Benign Chondroblastoma, epiphyseal Chondroblastoma)
- Xondromiksoidnaja fiʙroma
Malignant
- Xondrosarkoma
- Yukstakortikalnaya chondrosarcoma
- Mesenchymal chondrosarcoma
Giant cell tumor (osteklastoma)
Tumors of the bone marrow
- Sarkoma Juinga
- Retikulosarkome bones
- Lymphoma Bone
- Myeloma
Vascular tumors
Benign
- Gemangioma
- Limfangioma
- Angioneuroma (glomangioma)
Intermediate or undefined
- Gemangioэndotelioma
- Gemangiopericitoma
Malignant
- Angiosarkoma
Other connective tissue tumors
Benign
- Desmoplastic fibroma
- Lipoma
Malignant
- Fiʙrosarkoma
- Liposarcoma
- Malignant mezenhimoma
- Undifferentiated sarcoma
Other tumors
- Xordoma
- "Adamantinoma" long bones
- Nevrilemmoma (schwannomas, neurinoma)
- Nevrofibroma
Neklasifitsiruemye tumor
Tumor changes
- Solitary bone cyst (Easy one-part or a cyst)
- Aneurysmal bone cyst
- Yukstaartikulyarnaya bone cyst (intraosseous ganglion)
- Metaphyseal bone defect (neosteogennaya fibroma)
- Eosinophilic granuloma
- Fibroznaya dysplasia
- "Myositis ossificans"
- Brown tumor at hyperparathyroidism
The effectiveness of the treatment of tumors largely depends on the timeliness of diagnosis. Clinical diagnosis of malignant bone tumors often presents considerable difficulties. In recent years, for the purpose widely used method biopsy, allowing to determine the nature of the pathological process (tumor, inflammation, etc.). Besides, cytology makes it possible to determine the nature of the tumors (epithelial or non-epithelial), differentiate the primary lesion with secondary.
Puncture bones usually done after careful consideration of the medical history and x-ray evidence, and when a small lesion focus should be carried out under fluoroscopy.
