File:IPLab13CF3.jpg
This low-power photomicrograph of pancreas shows increased interstitial connective tissue resulting in accentuation of the lobular pattern.
File:IPLab13CF2.jpg
This section of duodenum demonstrates dilation, loss of rugae, and areas of ulceration (arrows).
File:IPLab13CF1.jpg
This is a gross photograph of liver and pancreas from the autopsy. The pancreas is slightly smaller than normal and it has a mucous consistency.

File:IPLab13WT10.jpg
This high-power photomicrograph shows the differences in cell morphology between the blastema (1) and the fibroblast type cells (2).
