STAT6 and solitary fibrous tumor: Among the 4 cases (samples 11, 12, 13, and 14, Table 1) for which FISH results were not available, three (11, 12, and 13) tumors presented known recurrent fusion events: EWSR1-cAMP responsive element binding protein 3 like 2 (CREB3L2) fusion in sclerosing epithelioid fibrosarcoma [13], EWSR1-FLI1 in a case of Ewing sarcoma, and NGFI-A binding protein 2 (NAB2)-STAT6 in a solitary fibrous tumor.
