Multiple Endocrine Neoplasia Type 1

Multiple Endocrine Neoplasia Type 1 (MEN1), also called Wermer syndrome, is an inherited tumor syndrome characterized by the development of tumors in multiple endocrine (hormone-producing) glands. The classic triad involves tumors of the parathyroid glands, pituitary gland, and pancreatic islet cells, though tumors can occur in other tissues as well.

Parathyroid tumors are the most common manifestation, occurring in 90-95% of individuals with MEN1, often causing hyperparathyroidism (elevated calcium levels) with symptoms including kidney stones, bone loss, fatigue, and cognitive changes. Pancreatic tumors occur in 30-80% of patients and may produce excessive hormones causing specific syndromes (like Zollinger-Ellison syndrome from gastrin-producing tumors). Pituitary tumors occur in 15-50% and may affect hormone production or cause headaches and vision problems.

Other tumors associated with MEN1 include adrenal cortical tumors, carcinoid tumors (particularly in the thymus, lungs, and stomach), lipomas (fatty tumors), and facial angiofibromas. While most tumors in MEN1 are benign, some can be malignant, particularly pancreatic and carcinoid tumors. Early detection through regular surveillance is critical.

MEN1 is caused by mutations in the MEN1 gene, which encodes a tumor suppressor protein called menin. The condition is inherited in an autosomal dominant pattern, meaning a 50% chance of passing it to each child. Regular screening protocols help detect tumors early, when they are most treatable. Surgical removal of affected glands is often necessary.
