Which condition is most likely to occur with a pancreatic tumor in MEN type 1?

In Multiple Endocrine Neoplasia (MEN) type 1, also known as Wermer's syndrome, there is a triad of endocrine tumors typically involving the pituitary gland, pancreas, and parathyroid glands. One of the key associations of pancreatic tumors in MEN type 1 is the development of gastrin-secreting tumors, known as gastrinomas, which are responsible for Zollinger-Ellison syndrome. This syndrome leads to excessive gastric acid production, resulting in peptic ulcers and often causing diarrhea.

Hypercalcemia is a hallmark of primary hyperparathyroidism, which is common in MEN type 1, but this condition primarily arises from parathyroid gland tumors rather than pancreatic tumors directly. Hyperthyroidism is associated with thyroid gland tumors, and while hyperlipidemia can be found in various metabolic and endocrine disorders, it is not specifically tied to pancreatic tumors in MEN type 1.

Hypoglycemia can indeed occur in the context of insulinomas, another type of pancreatic tumor in MEN type 1. However, the correct choice focuses on the association of pancreatic tumors with hypercalcemia due to parathyroid involvement. Therefore, hypercalcemia, resulting from parathyroid adenomas typically seen in MEN type
