Additionally, GLUT1 is a sensitive immunohistochemical marker for perineural cells and a subset of mesenchymal neoplasms, including chordoma, desmoplastic small round cell tumors, desmoid-type fibromatosis, epithelioid sarcoma, gastrointestinal stromal tumor, myoepithelioma, schwannoma, and undifferentiated pleomorphic sarcoma [5,11]. Here, SLC2A1 is linked to epithelioid sarcoma.
