Aetiology
- Hypoplasia of panceatic islets where exocrine cells are functional
- Degeneration of the islet cells occurs in acute pancreatic necrosis along with acinar tissue necrosis, atrophy occurs during chronic interstitial pancreatitis
- Extensive neoplastic destruction may also contribute to islet loss
- Causes Diabetes mellitus (DM)
- In cats
- Amyloidosis of the islets is sometimes observed and may be restricted to just them
- May result in signs of DM or have no symptoms
- Hydropic (vacuolar) degeneration of beta cells
- Acumultion of glycogen within the cytoplasm
- Develops in response to long-term overstimulation due to peripheral insulin resistance
- Amyloidosis of the islets is sometimes observed and may be restricted to just them
- In dogs
- Sclerosis of the islets is sometimes observed in dogs with DM without pancreatic necrosis but also in dogs without DM
