Pathology of Eosinophilic Pancreatitis

Dr Sampurna Roy MD             


Eosinophilic pancreatitis (EP) is a rare disease.

It typically occurs in the setting of either eosinophilic gastroenteritis or the hypereosinophilic syndrome.

Isolated eosinophilic infiltration of the pancreas is less common.     

Clinical presentation: EP usually presents as a pancreatic tumour with abdominal pain and/or obstructive jaundice.

The diagnosis is often not made until after pancreatic resection under suspicion of a pancreatic tumour.

Microscopic features:  Patients with eosinophilic pancreatitis may show two distinct histologic patterns:

1) a diffuse periductal, acinar, and septal eosinophilic infiltrate with eosinophilic phlebitis and arteritis; and 

2) localized intense eosinophilic infiltrates associated with pseudocyst formation.

Differential diagnosis: Prominent eosinophilic infiltrates are an unusual finding in the pancreas. 

Other causes of eosinophilic infiltrates include pancreatic allograft rejection, pancreatic pseudocyst, lymphoplasmacytic sclerosing pancreatitis (LPSP), inflammatory myofibroblastic tumor, and histiocytosis X.
