Figure 4 Well-differentiated pancreatic vipoma: Immuno-histochemical analysis (x 10) on 4 μm thick, serial sections of a paraffin block of the tumor. Stains for Chromogranine-A (A) and Ki-67 (B) are shown. In (A) an almost uniform and intense expression of Chromogranine-A is depicted. The tumor has a low proliferative rate as assessed by Ki-67 labeling (arrow-heads) with a mean index < 2% (B).
