The results showed that the sarcoma was negative for CD34, S100 Calcium Binding Protein B (S100B), Desmin, H-Caldesmon Antibody (h-CALD), Signal Transducer And Activator Of Transcription 6 (STAT6), CD117 (YR145), β-Catenin, SRY-Box Transcription Factor 10 (SOX10), smooth muscle Actin (SMA), epithelial membrane antigen (EMA), Cytokeratin AE1/AE3 [CK (AE1/AE3)], Anaplastic lymphoma kinase 5A4 [ALK(5A4)], SS18-SSX, CD31, ERG, MyoD1, leukocyte common antigen (LCA)', CD21, CD35, Somatostatin Receptor 2 (SSTR2), Myogenin, and Pan Trk (Figure 1B).
