Definition
An intraosseous benign tumor of notochord origin that arises in the bones of the base of the skull, vertebral bodies, sacrum or coccyx. It contains vacuolated tumor cells without atypia, but lacks myxoid matrix, necrosis, and lobular architecture, which are features that characterize its malignant counterpart, chordoma. Most lesions are incidental findings.

Names
CancerIndex is a research and information platform. It does not diagnose and does not recommend treatment.
Key figures
Each figure carries its unit, period and source; ranks link to "Why this rank?".
No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
