Results: The histopathological changes seen in lymph node were metal debris containing sinusoidal macrophages in a background with numerous epithelioid granulomata in the remaining lymph node. Conclusion: The identification of regional lympadenopathy in patients with past history of malignancy usually indicates metastatic disease. Post-prosthesis lymph node histiocytosis resembling metastatic disease is described, and that is why we need resect and examine lymph nodes with the use of polarized light microscopy to identify birefringent particles of prosthetic debris for an accurate histologic diagnosis. Objective: Chordoma is a slow-growing malignant bone tumor that exhibits notochordal differentiation. Nearly 90 % of cases occur in the sacrococcygeal region and in the base of the skull. The remaining cases develop in the mobile spine, predominantly in the cervical and lumbar vertebrae. We report a rare case of paravertebral mediastinal chordoma without bone destruction. Method: Case report.
