Case: AP323
Contributor's Comment: Despite the arrangement of the tumor cells in cords in myxoid stroma, high magnification showed rhabdoid cytology with conspicuous nucleoli while physaliferous cells were not obvious. In addition, chordoid meningioma is not common in pediatric patients. INI-1 stain was required and it showed loss of INI-1 staining in the tumor cells in this case.
