Sacrococcygeal chondroid chordoma: a case report and literature review

Abstract

Chordomas are low-grade malignant tumours that arise from remnants of the notochord, usually from within the vertebral bodies It accounts for 1%-4% of malignant primary bone tumours, 50% of which are located in the sacrococcygeal region. It's annual incidence is 0.1/100 000 population. The greatest incidence was found between the fifth and the seventh decades with a male predominance. In spite of its slow-growing nature, chondroid chordoma tends to relapse, and it may eventually become malignant, often jeopardising the patient's prognosis. We report the case of sacrococcygeal chondroide chordoma and the treatment performed.
