In vivo and ex vivo confocal endomicroscopy of pancreatic cystic lesions: A prospective study

Figure 2 In vivo endoscopic ultrasound guided needle based confocal laser endomicroscopy, ex vivo confocal laser endomicroscopy, and histopathology of mucinous cystic neoplasms. Panels A, B, and C are from subject 3 (low grade). Panels D, E, and F are from subject 4 (low grade). Panels G, H, and I are from subject 5 (low to moderate grade). Epithelial bands with incomplete papillary formation are observed in CLE. The in vivo CLE demonstrates horizon like bands where ex vivo CLE demonstrates better defined epithelial bands. Corresponding histopathology (panel C, × 40 and panel F, × 20) show low grade dysplasia and panel I (× 40) reveals moderate grade dysplasia. CLE: Confocal laser endomicroscopy.
