Figure 5 Histopathologic findings (HE × 200). A: Histopathological examination showed the presence of cystically dilated ducts with formation of papillary growth lined by mucin-secreting columnar epithelium at the level of the pancreatic head; B: The mucin-secreting epithelium reveals stratification of atypical nuclei. No obvious stromal invasion was seen and the features suggested a diagnosis of intraductal papillary mucinous carcinoma, noninvasive type; C: The section of the pancreatic body showed that it was focally involved by the lesion (arrow); D: The section of the pancreatic tail showed the focal presence of atypical ducts.
