Figure 4

Pathological findings of pancreatic tumor obtained by EUS-FNA and surgical resection. Tumor tissues were obtained from a tumor of the tail of the pancreas. Tumor tissue comprised a cluster of mild atypical cells with clear cytoplasm on hematoxylin and eosin staining (a). IHC stain of tumor tissue obtained by EUS-FNA showed that CD10 (b) and NSE (c) were positive and synaptophysin (d), MUC6 (e), and cytokeratin 7 (f) were negative. PAX-8 (g) and vimentin (h) were positive in tumor tissue obtained by surgical resection.
