Immunohistochemical comparison between S100A10 and annexin A2 (ANX A2) in case 1. I: Tumor components with tumor buds and PDCs. a Immunolocalization is basically similar to those in Fig. 2b and c. S100A10 immunostain. b Image corresponds to (a). Immunoreactivity for ANX A2 is almost the same as that for S100A10. Arrowheads and asterisks indicate the same information presented in Fig. 2c, respectively. ANX A2 immunostain. c Image corresponds to both (a) and (b). The changes in the shape of tumor glands are more visible with pan-cytokeratin immunostain. AE1/AE3 immunostain. Bars: 100 μm
