Overview
Osteosarcoma may be classified according to the World Health Organization’s histologic classification of bone tumors into three groups: central (medullary) tumors, surface (peripheral) tumors, and extraskeletal tumors.[1]
Classification
Osteosarcoma may be classified according to the World Health Organization’s histologic classification of bone tumors into three groups:[1]
Central (medullary) tumors:
- Conventional central osteosarcomas.
- Telangiectatic osteosarcomas.
- Intraosseous well-differentiated (low-grade) osteosarcomas.
- Small-cell osteosarcomas.
Surface (peripheral) tumors:
- Parosteal (juxtacortical) well-differentiated (low-grade) osteosarcomas.
- Periosteal osteosarcoma: Low-grade to intermediate-grade osteosarcomas.
- High-grade surface osteosarcomas.
Extraskeletal:
- Extraskeletal osteosarcomas.
