EZH2 and thymoma: When considering the percent of tumor cells staining as a continuous variable, thymic carcinomas had significantly more diffuse EZH2 staining compared to type A thymoma (p < 0.0001) and MNTLS (p < 0.0001), but not when compared to type B3 thymoma (p = 0.055, Wilcoxon rank sum tests, Figure 1 and Figure 2).
