Background: Sacrococcygeal chordomas are rare and difficult to diagnose tumors.
Case report: A 73-year-old man in the last 6 months felt a pain in and around the coccyx when sitting and especially when rising from the sitting position. He consulted his family physician and was referred by him to a general surgeon with the diagnosis of pilonidal disease. During the operation, the surgeon found an unusual mass and performed a wedge biopsy of the tumor. When chordoma was returned as the diagnosis, the patient was referred to our tertiary hospital for further treatment. The sacrococcygeal chordoma was excised en bloc with the coccyx and the fifth sacral vertebra by posterior approach.
Conclusions: Because of minimal response to chemo- and radio-therapy, resections with wide margins at initial surgery is the most important factor influencing local recurrence.
