Microscopic findings of four additional OFMTs with PHF1-TFE3 fusions. Tumors displayed a typical morphology, such as OFMT#3 arising in the abdominal wall of a 69-year old female (A); OFMT#4 arising in the deep soft tissue of the posterior neck in a 59-year-old-female (B), a malignant OFMT, OFMT#2, arising in the deep soft tissue of the thigh in a 62-year-old male (C); and a malignant OFMT, OFMT#5 arising in the scapula of a 64-year-old male (D). These tumors were composed of ovoid to epithelioid tumor cells, arranged in reticular, fascicular, and trabecular patterns, with the malignant tumors showing increased cellularity. The microscopic features of these four OFMTs with PHF1-TFE3 fusions match that of a malignant OFMT with a PHF1-MEAF6 fusion as shown in Figures 3E–F for comparison
