We report the case of a 79-year-old woman referred to our institution for persistent cough and right-sided chest pain. A computed tomographic scan revealed a 2-cm round nodule in the right lower lobe. A wedge resection of the lesion was achieved by video-assisted thoracic surgery. Pathologic examination was consistent with the diagnosis of chordoma. Magnetic resonance imaging of the whole spine and skull basis was normal. Therefore, a diagnosis of primary lung chordoma, an exceptional condition, could be established.

: EnBloc resections of bone tumors of the spine are very demanding as the target to achieve a tumor-free margin specimen (sometimes impossible due to the extracompartimental tumor extension) is sometimes conflicting with the integrity of neurological functions and spine stability. : The surgical treatment of a huge multi-level chordoma of the thoracic spine with unusual extension is reported. Anteriorly, the tumor widely invaded the mediastinum and displaced the aorta; on the left side, it expanded in the subpleuric region; posteriorly, it was uncommonly distant 13 mm from the posterior wall.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Objective: Skull base chordomas (SBCs) often present with cranial nerve (CN) VI deficits. Studies have not assessed the prognosis and predictive factors for CN VI recovery among patients presenting with CN VI deficits.
Methods: The medical records of patients who underwent resection for primary chordoma from 2001 to 2020 were reviewed.

The sacrum can harbor a diverse group of both benign and malignant tumors, including metastases. Primary tumors of the sacrum can arise from bone, cartilage, marrow, notochordal remnants, or surrounding nerves and vessels. Among a variety of primary tumors of the spine, chordoma, germ cell tumors and Ewing's sarcoma are recognized for their propensity to occur in the sacrum.
