'''Insulinomas''' are slow growing, well-encapsulated, functional tumours of the beta cells of the pancreatic islet cells.  They secrete inappropriately high amount of insulin irrespective of the serum glucose level.  They are predominantly malignant (90% of canine insulinomas), with a high metastatic rate to regional lymph nodes, liver and omentum.  60% of isulinomas are carcinomas, which are more likely to be endocrinologically active, the others being adenomas.
