Fig. 1: Imaging and gross findings of NFATc2-rearranged sarcomas.

a, b (case 4), magnetic resonance imaging with STIR (Short tau inversion recovery) showing a large tumor replacing the medullary cavity of the distal femur associated with a massive extra-osseous component. Grossly, the tumor was a large fleshy mass with hemorrhagic areas and multilobular contours. c, d (case 7), radiograph of the surgical specimen showing an ill-defined lytic mass growing posteriorly into the soft tissues. Grossly, the tumor manifested as a large destructive fleshy mass breaking through the cortex and invading the surrounding tissues, note the marked periosteal reaction. Scale bars 5 cm.
