Study of differtent types of chordomas, a case series

Chordoma is a rare, low grade, primary malignant bone tumour arising from primitive notochord remnants. It accounts for 1-4% of all primary skeletal tumours. Sacrum represents the more common anatomical site of origin followed by skull base region, cervical vertebrae and thoracolumbar vertebrae. Ours is a case series of three patients diagnosed to be suffering from different types of chordoma’s, that is conventional, chondroid and de-differentiated based on histopathology, immuno-histochemistry and radiological findings.
