Metastatic chordoma to the mandible

Area of Science:

• Oncology
• Orthopedic Oncology
• Neurosurgery

Background:

• Chordomas are rare, slow-growing bone tumors originating from notochordal remnants.
• They most commonly occur in the sacrum and spine, with distant metastasis being infrequent.
• Spinal cord tumor management typically involves surgical excision and adjuvant radiation therapy.

Observation:

• This case details a patient with a primary sacral chordoma.
• Four years after initial treatment, metastasis to the mandible was diagnosed.
• The mandibular lesion presented as a distinct clinical challenge.

Findings:

• This represents the first documented instance of chordoma metastasis to the mandible in medical literature.
• The mandibular chordoma showed resistance to radiation therapy.
• Surgical resection was effective in controlling the mandibular tumor.

Implications:

• This case highlights the potential for rare distant metastasis in chordomas, even after primary tumor control.
• It underscores the need for vigilance in monitoring for unusual metastatic patterns.
• The findings suggest that surgical management may be a primary treatment option for mandibular chordoma recurrence or metastasis.
