Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))
Upper limits of pancreas weight[1][notes 1]
Patient age Men Women
<20 years 115g 80g
21-30 years 115g 125g
31-40 years 155g 140g
41-50 years 155g 110g
51-60 years 175g 125g
>60 years 160g 110g
Overall 160g 120g

In autopsy

Inspect the pancreas regarding color and consistency. ((Separate it and measure its dimensions.))

Cut it in consecutive short axis slices.[notes 2] Note the appearance of the parenchyma (and the size of the duct).

Microscopic examination

Look for pancreatic intraepithelial neoplasia and pancreatic tumors.

  • Pancreatic lipomatosis is a common finding. This case shows moderate to severe lipomatosis, with mainly interlobular but also scattered intralobular fatty infiltration. Reporting is optional in at least mild to moderate cases.

Notes

  1. ↑ Upper limit is calculated as mean plus 2 standard deviations.
  2. ↑ The pancreas may also be cut in the longitudinal plane.
