Study Notes
Bone and Cartilaginous Tumors: Key Characteristics and Types
- Chondrosarcomas lead to hematogenous metastasis, particularly to the lungs and skeleton, and require wide excision for treatment.
- Fibrous and fibroosseous tumors, such as fibrous cortical defect and nonossifying fibroma, are developmental disorders often detected incidentally, typically smaller than 5 mm, and common in the distal femur and proximal tibia.
- Fibrous dysplasia, a benign tumor, is caused by GNAS gene mutations and exists in three clinical forms: monostotic, polyostotic, and a form associated with endocrine disorders, skin pigmentations, and precocious puberty due to McCune Albright Syndrome.
- Monostotic fibrous dysplasia cases, which make up 70% of instances, often occur in the ribs, femur, tibia, jaw bones, skull, and humerus and can cause significant enlargement, deformity, pain, and pathological fractures.
- Poliostotic fibrous dysplasia, found in younger individuals, is not accompanied by endocrine disorders and tends to involve the femur, skull, tibia, and humerus, causing severe deformity and spontaneous fractures.
- Bone lesions with osteoclast-like giant cells, including giant cell tumor, aneurysmal bone cyst, and others, are benign but locally aggressive, occurring predominantly in people aged 20-40 and often located around the knee epiphysis.
- Aneurysmal bone cyst, comprising about 2.5% of all bone tumors, is a benign locally destructive neoplasm commonly found in skeletally immature patients, especially in the first two decades of life.
- Chordoma is a malignant tumor arising from notochord residues in intervertebral discs, typically located in the sacrococcygeal vertebra region and diagnosed with the BRACHURY marker.
- Metastatic bone tumors are the most common bone tumors, with over 75% originating from prostate, breast, kidney, and lung cancers in adults, and from neuroblastoma, Wilms tumor, and rhabdomyosarcomas in children.
- Ewing sarcoma, a small round cell malignant tumor of bone and soft tissue, is the second most common primary bone sarcoma after osteosarcoma, often diagnosed in individuals under 20 years old.
- Osteogenic tumors, Ewing's sarcoma, chondroblastoma, and giant cell tumor typically occur in individuals under 20 years old, while chondrosarcoma is more common in individuals over 50.
- Osteosarcoma is usually located in the metaphysis of long bones, chondrosarcoma in the pelvis and proximal ends of long bones, and Ewing sarcoma in the diaphysis of long bones, providing insight into the localization of these tumors.
