We report a case of digital extra-axial extra-osseous soft-tissue chordoma located in a flexor synovial sheath of the little finger of the left hand. Histology-immunohistochemistry (brachyury) analysis after broad en-bloc resection confirmed the diagnosis. Exhaustive MRI assessment of the entire spine, skull and pelvis found no other locations. No recurrence was reported at last follow-up. Hand surgeons should be aware of the diagnosis and treatment of brachyury-positive extra-axial soft-tissue chordomas, whence the importance of recognizing its typical and differential characteristics to guide optimal therapeutic strategy.
