==Overview==
Multiple endocrine neoplasia (MEN) encompasses several distinct [[syndrome]]s featuring [[Endocrine gland neoplasm|tumors of endocrine gland]]s, each with its own characteristic pattern. Multiple endocrine neoplasia may be classified according to [[tumor]] characteristics into 3 subtypes: [[Multiple endocrine neoplasia type 1]], [[Multiple endocrine neoplasia type 2a]], and Multiple endocrine neoplasia type 2b.
==Multiple Endocrine Neoplasia==
* The term multiple endocrine neoplasia (MEN) encompasses several distinct [[syndrome]]s featuring [[Endocrine gland neoplasm|tumors of endocrine gland]]s, each with its own characteristic pattern.  In some cases, the [[tumor]]s are [[malignant]], in others, [[benign]]. [[Benign]] or [[malignant]] [[tumor]]s of nonendocrine [[tissue]]s occur as components of some of these [[tumor]] [[syndrome]]s.
* MEN syndromes are inherited as [[autosomal dominant]] disorders.<ref>{{DorlandsDict|six/000070637|multiple endocrine neoplasia}}</ref>

==Terminology==
{{SK}} MEN syndromes; Familial endocrine adenomatosis; Multiple endocrine adenomatosis; Multiple endocrine neoplasia syndrome; MEN; MEN-Multiple endocrine neoplasia syndrome; Multiple endocrine neoplasms
* The older names, "multiple endocrine [[adenomas]]" and "multiple endocrine [[adenomatosis]]" (MEA), have been replaced by the current terminology.
* The term multiple endocrine neoplasia is used when two or more [[endocrine]] [[tumor]] types, known to occur as a part of one of the defined MEN syndromes, occurs in a single patient and there is evidence for either a causative [[mutation]] or hereditary transmission. The presence of two or more [[tumor]] types in a single patient does not automatically designate that individual as having MEN because there is a small statistical chance that development of two "sporadic" [[tumor]]s that occur in one of the MEN syndromes could occur by chance.

* In 1903 Erdheim described the case of an acromegalic patient with a [[pituitary adenoma]] and three enlarged [[parathyroid gland]]s.
* In 1953 Underdahl ''et al.'' reported a case series of 8 patients with a [[syndrome]] of [[pituitary]], [[parathyroid]], and pancreatic islet [[adenoma]]s.
* In 1954 Wermer noted that this [[syndrome]] was transmitted as a dominant trait.
* In 1959 Hazard ''et al.'' described medullary (solid) [[thyroid carcinoma]].
* In 1961 Sipple described a combination of a [[pheochromocytoma]], [[medullary thyroid carcinoma]] and [[parathyroid adenoma]].
* In 1966 Williams ''et al.'' described the combination of mucosal neuromas, [[pheochromocytoma]] and [[medullary thyroid carcinoma]].
* In 1968 Steiner ''et al.'' introduced the term "multiple endocrine neoplasia" (MEN) to describe disorders featuring combinations of [[endocrine]] [[tumor]]s and proposed the terms '[[Wermer syndrome]]' for MEN 1 and '[[Sipple syndrome]]' for MEN 2.
* In 1974 Sizemore ''et al.'' showed that the MEN 2 category included two groups of patients with MTC and [[pheochromocytoma]]: one with [[parathyroid]] [[disease]] and a normal appearance (MEN 2A) and the other without [[parathyroid]] [[disease]] but with mucosal neuromas and mesodermal abnormalities ([[MEN 2B]]).
* In 1988 the [[MEN1]] [[locus]] was assigned to [[Chromosome]] 11 (11q13).

The causative mutation is in the MEN1 gene at 11q13 which encodes a nuclear protein called menin that is believed to act as a tumor suppressor. Most cases of multiple endocrine neoplasia type 1 are inherited in an [[autosomal dominant]] pattern.

MEN syndrome types 2 and 3 have their basis in molecular genetics. Individuals can be tested for this genetic disorder reliably even when asymptomatic. The mutation is in the [[RET proto-oncogene]]. Most cases of multiple endocrine neoplasia types 2 and 3 are inherited in an [[autosomal dominant]] pattern.

Type 2 is also known as Sipple syndrome (after the American Dr John H. Sipple, who described it in 1961)<ref>Sipple JH. ''The association of pheochromocytoma with carcinoma of the thyroid gland.'' Am J Med 1961;31:163-166.</ref> and used to be called type 2A:
 
#[[Medullary carcinoma]] of the [[thyroid]] which is associated with increased [[calcitonin]] secretion. A test for elevated calcitonin should be done after [[pentagastrin]] injection and/or calcium infusion, to ensure that all affected patients are detected.  
#[[Pheochromocytoma]]
#[[Parathyroid]] hyperplasia/tumour causing [[hyperparathyroidism]].
 
===MEN type 3/type 2b===
This syndrome has no eponym; it was described by Schimke ''et al'' in 1968.<ref>Schimke RN, Hartmann WH, Prout TE, Rimoin DL. ''Syndrome of bilateral pheochromocytoma, medullary thyroid carcinoma and multiple neuromas. A possible regulatory defect in the differentiation of chromaffin tissue.'' [[N Engl J Med]] 1968;279:1-7. PMID 4968712</ref> Originally thought to be a third MEN, then considered a variant of II (especially after linkage to ''RET'' was confirmed), it is now considered its own syndrome.
#[[Pheochromocytoma]]
#Medullary carcinoma of [[thyroid]] which is associated with increased [[calcitonin]] secretion. A test for elevated calcitonin should be done after pentagastrin injection and/or calcium infusion, to ensure that all affected patients are detected.
#Mucosal neuromas which are usually situated in the [[gastrointestinal tract]].

Overview

Multiple endocrine neoplasia (MEN) encompasses several distinct syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. Multiple endocrine neoplasia may be classified according to tumor characteristics into 3 subtypes: multiple endocrine neoplasia type 1, multiple endocrine neoplasia type 2 and multiple endocrine neoplasia type 4.
