SFT and hemangiopericytoma were previously considered distinct; however, as most tumors exhibit the characteristic NGFI‐A‐binding protein 2 (NAB2)‐signal transducer and activator of transcription 6 (STAT6) gene fusion [3, 4], they have been recognized as a single disease [1, 2]. Here, STAT6 is linked to solitary fibrous tumor.
