Thoracic chordoma in a 36-year-old female.

Chordomas are rare tumors that occur in the bones of the skull base and spine, affecting 1 in 1 000 000 people per year. Thoracic chordomas comprise just 1% of chordomas. A 36-year-old female underwent a right video-assisted thoracoscopic surgical resection for a cystic mass at the level of T2-3 which was well-circumscribed. Despite efforts to achieve an intact resection, there was tumor spillage due to friability, and it was taken off the bony vertebral body with no margin. The final pathologic diagnosis was chordoma. Thoracic chordomas are rare, slow-growing, recurring neoplasms that require proper preoperative diagnostic imaging and ideally preoperative trocar computed tomography-guided biopsy from a posterior approach if anatomic access is possible. They are prone to dissemination and sarcomatous differentiation. The surgical approaches for reported thoracic chordoma tumors vary due to their rarity and the variation in tumor location and presentation.
