Chordomas are rare malignant tumors that originate from remnants of the notochord, a primitive structure present during fetal development. Although they can occur along the entire axial skeleton, they most frequently develop at the base of the skull or along the sacrococcygeal region, which includes the area at the tailbone’s base. When a chordoma forms at this location, it can present unique challenges in diagnosis and management due to its deep-seated position and proximity to vital structures.
The tailbone, or coccyx, is a small, triangular bone at the bottom of the vertebral column. While many may consider it a minor part of the skeletal system, tumors in this area can significantly impact quality of life. Chordomas at the base of the tailbone often grow slowly but can become quite large before symptoms prompt medical attention. The slow progression sometimes leads to delayed diagnosis, as initial signs may be subtle or mistaken for benign conditions.

Patients might notice a palpable mass or swelling in the area, and in some cases, neurological symptoms such as numbness, weakness, or bowel and bladder disturbances can occur if the tumor compresses nearby nerves or the spinal cord. Because of the deep location, physical examination alone may not suffice, necessitating advanced imaging techniques to evaluate the tumor’s extent.
Imaging studies play a crucial role in diagnosing a chordoma. MRI scans are particularly valuable, providing detailed images of soft tissues and helping delineate the tumor boundaries. CT scans assist in assessing bone involvement or destruction. A biopsy, often guided by imaging, is essential for confirming the diagnosis histologically. Under the microscope, chordomas display characteristic physaliphorous cells—large cells with bubbly, vacuolated cytoplasm. Chordoma at the Base of Tailbone
Treatment strategies for a sacrococcygeal chordoma primarily involve surgical removal. Given the tumor’s location, complete excision can be technically challenging, requiring specialized surgical expertise. The goal is to remove as much of the tumor as possible while preserving function and minimizing damage to surrounding tissues. Achieving clear margins is critical because chordomas have a high propensity for local recurrence if residual tumor remains. Chordoma at the Base of Tailbone
Radiation therapy, especially high-dose proton beam therapy, often complements surgery. It can target residual tumor cells and reduce the risk of recurrence. Chemotherapy has limited effectiveness against chordomas, but ongoing research explores targeted therapies and immunotherapy options. Chordoma at the Base of Tailbone
Prognosis depends on factors such as tumor size, extent of local invasion, and success in achieving complete resection. Because of the tumor’s slow-growing nature, patients can live many years post-treatment, but long-term follow-up is essential due to the risk of recurrence and distant metastases, which, although less common, may occur.
Living with a diagnosis of a chordoma at the tailbone’s base requires a multidisciplinary approach involving oncologists, surgeons, radiologists, and rehabilitation specialists. Advances in surgical techniques and radiotherapy have improved outcomes, enabling many patients to maintain a reasonable quality of life despite the diagnosis.
Early detection and treatment are vital. If persistent lower back or tailbone pain occurs, especially if associated with a noticeable mass, seeking medical evaluation promptly can lead to earlier diagnosis and better management outcomes. Chordoma at the Base of Tailbone
