However, STAT6 positivity is not entirely exclusive to SFT, as it has been reported in a subset of soft tissue neoplasms (Table 1), including liposarcoma/myxoid liposarcoma, desmoid fibromatosis, deep fibrous histiocytoma, unclassifiable sarcoma, neurofibroma, undifferentiated pleomorphic sarcoma, low-grade fibromyxoid sarcoma, and ovarian fibroma [3,5]. This evidence concerns the gene STAT6 and solitary fibrous tumor.
