Pancreas - Parasitic Pathology

Parasites become important if they occlude the pancreatic duct directly or induce inflammation
Commonly caused by flukes of families Opisthorchidae and Dicrocoelidae when present in large numbers and overspill from the billiary tract
Nematodes, particularly ascarids, and cestodes occasionally lodge within pancreatic ducts
In pigs, Stephanurus dentatus can form cysts in the pancreas after migration through the liver
Parasites tend to cause chronic interstitial pancreatitis
Tend to destroy acinar tissue, islets of Langerhans being unaffected
