In the findings of the current study, SEF and LGFMS exhibit strong MUC4 expression (Figures 20, 22), other sarcoma types including fibrosarcoma (Figure 2), liposarcoma (Figure 6), MPNST (Figure 9), myxofibrosarcoma (Figure 11), and leiomyosarcoma (Figure 18) showed no MUC4 expression. Here, MUC4 is linked to malignant peripheral nerve sheath tumor.
