POSTN immunohistochemical reaction in the three types of testicular neoplasms considered. Difference between tumours has been noted in: ( A ) the number of positive cells and ( B ), the intensity of the reaction ( p < 0.0001). P-value obtained by the Kruskal-Wallis ANOVA analysis with post-hoc Dunn test: * p < 0.0001; ** p < 0.0001; *** p < 0.0001; **** p < 0.0001
