Figure 3. Pathologic findings of OFMTs with CREBBP-BCORL1 (A–F) and KDM2A-WWTR1 fusions (G–I).

Figure 3

Case#1 was composed of uniform evenly-spaced small round cells arranged in cord-like structures in a fibromyxoid to hyalinized stroma (A,B), which based on the increased cellularity and mitotic activity was classified as malignant (arrows, C). Case#3 showed alternating collagenous and myxoid areas with focal microcystic change (D), with bland round cells with uniform nuclei and scant cytoplasm (E) arranged in cord-like to reticular patterns (F). The KDM2A-WWTR1 positive OFMT#2 was located within dermis (G) and superficial subcutis. It was composed of uniform ovoid tumor cells set in a loose fibromyxoid background (H). The tumor showed distinctive giant collagen rosettes throughout (I).
