Summary

Excerpted from the GeneReview: Multiple Endocrine Neoplasia Type 4
Multiple endocrine neoplasia type 4 (MEN4) is characterized by the development of endocrine tumors, especially those involving the parathyroid and/or pituitary gland. Parathyroid adenomas and parathyroid hyperplasia manifest as hypercalcemia (primary hyperparathyroidism) as a result of the overproduction of parathyroid hormone. Anterior pituitary adenomas can secrete adrenocorticotrophic hormone (ACTH), growth hormone (GH), prolactin, or are nonfunctional (nonsecreting) adenomas. Well-differentiated endocrine tumors of the gastroenteropancreatic tract, carcinoid tumors, and adrenocortical tumors can also occur.
