Extraosseous chordomas are extremely rare. In this case report, we describe an extraosseous chordoma in the coccygeal region that later metastasized to the cerebellum. A 30-year-old man presented with a progressively enlarged lesion in the coccygeal region with painful sensation. Preoperative computed tomography and magnetic resonance imaging showed a large lobular mass in the coccygeal region without sacrococcygeal destruction. Pathology showed physaliphorous cells and the immunohistochemical staining pattern typical of chordoma.
