Malignancy risk factors and prognostic variables of pancreatic mucinous cystic neoplasms in Chinese patients

Figure 2 Representative micrographs showing the mucinous cystic neoplasm. A: The epithelium exhibits mild to moderate cellular and structural dysplasia, and there is subepithelial ovarian-type stroma (OTS), haematoxylin-eosin staining (H&E) × 200; B: The epithelium demonstrates papillary hyperplasia with some cells shedding into the lumen, and the stroma is partially replaced by fibrous collagen, H&E × 100; C: MCN-associated invasive carcinoma extended into the adjacent pancreatic tissue, and the epithelium exhibited severe dysplasia, H&E × 100; D: The OTS was positive for PR-staining, EnVision × 200.
