Case Reports
Transoral resection and reconstruction for primary osteogenic sarcoma of the second cervical vertebra.
A case of primary osteogenic sarcoma at the second cervical vertebra is reported. ⋯ The axis is a very rare location for the occurrence of primary osteosarcoma. Osteosarcoma may histologically mimic chondroblastoma. The axis can be surgically exposed, resected, and instrumented transorally. The stabilization must be augmented by posterior occipitocervical fusion.
