Unlabelled:
Sacral chordoma (SC) is a malignant bone tumor with high risk of local recurrence (LR) even after en bloc resection, generally in the first 10 years after resection. We report two cases of late LR, at 17 and 19 years. Two male patients, aged 45 and 53 years, presented with large SC needing a combined approach for en bloc resection. Surgical margins were safe for the first patient and borderline for the second. The patients had yearly follow-up. The first patient developed LR on the posterior wall of the right acetabulum and the second developed LR in the right sciatic notch, at 17 and 19 years, respectively. These two cases of very late LR of SC advocate for yearly screening of patients even more than 20 years after resection.
