Pancreas - Nodular Hyperplasia
Neoplasia
- Originates from the exocrine tissue or excretory ducts
- Neoplasia of the Islet cells is rare but may cause hypoglycaemia due to overproduction of insulin
Adenoma
Carcinoma

- In older dogs, more common in Airedale terriers, rare in cats, other species too
- Tend to arise centrally in the gland
- Highly invasive and infiltrative
- Metastases to the liver, visceral serosa, abdominal lymph nodes, spleen, adrenals etc.
- Similar to malignant ovarian tumours - implant on the peritoneum
Gross appearance
- Usually spherical nodules with adhesions to nearby structures
- Single or multiple, variable size
- Greyish or yellow fibrous tissue - firm on cutting
- May show internal necrosis and haemorrhage
- Some tumours may contain cysts wih mucinous content
- Adhesions may occur
Microscopic appearance
- May be well differentiated with normal acini and ducts
- Or diffuse sheet of undifferentiated cells
