Abstract

Extra-axial soft tissue chordoma is rare. We report a case of extra-axial soft tissue chordoma of the right wrist in an 87-year-old man. The tumor was large, and the cut surface showed multinodular and myxoid appearance. Microscopically, nests of epithelioid and spindle cells were observed in the myxoid matrix. Vacuolated cells were also observed. The tumor cells were diffusely positive for brachyury and cytokeratin 19 on immunohistochemistry, suggesting that the tumor was extra-axial soft tissue chordoma. Extra-axial chordoma is the same entity as chordoma periphericum (parachordoma), as proposed by Laskowski and Dabska.
