Definition / general
- Most common malignant bone tumor is metastatic carcinoma
- In adults, 80% from prostate, breast, kidney, lung or thyroid
- In children, from neuroblastoma, Wilm tumor, osteosarcoma, Ewing / PNET or rhabdomyosarcoma
- Intraspinal seeding may occur along Batson’s plexus of veins
- Positive isotope bone scans (versus myeloma)
- Sarcomatoid carcinoma: consider if patient 60+ years with spindling bone malignancy; cells usually plumper than bone sarcomas and accompanied by carcinoma; renal cell carcinoma is most common primary site
- Common sites: axial skeleton, proximal femur, proximal humerus; usually marrow; very rare to be distal to elbow or knee
- Solitary metastases: kidney, thyroid
- Small bones of hands and feet: colon, lung, kidney
- Blastic lesions: prostate, carcinoid tumor, neuroendocrine tumors
