Which hormone-secreting islet cell tumor pairs are commonly included?

Explanation:
Pancreatic islet cell tumors, or pancreatic neuroendocrine tumors, secrete hormones. Among these, the two most commonly tested functioning tumors are insulinoma and gastrinoma. Insulinoma comes from beta cells and causes hypoglycemia due to excess insulin, while gastrinoma secretes gastrin, leading to excess stomach acid and ulcers. These two are classic examples you’ll see highlighted in questions about islet cell tumors. The other pair listed involves rarer hormone-secreting islet tumors, and the last option isn’t an islet cell tumor at all (it’s non-islet pancreatic or lymphoid pathology).
