Multiple endocrine neoplasia

Multiple endocrine neoplasia
Classification & external resources
ICD-10 D44.8
MeSH D009377

The term multiple endocrine neoplasia (MEN) encompasses several distinct syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. In some cases, the tumors are malignant; in others, they are benign.

The older names "multiple endocrine adenomas", or "multiple endocrine adenomatosis" -- "MEA" -- should not be used.

The presence of any one tumor type does not automatically have a patient labelled as MEN, but a search of the other at-risk areas is usually undertaken, especially when there are suggestive clinical signs. Confusingly, a single report of "MEN4" (OMIM 610755) has appeared.

The "MEN" syndromes discussed in this article are not the only medical conditions in which multiple endocrine tumors occur. Others include Carney complex and McCune-Albright syndrome. In general medical parlance, however, and in this article, "MEN" refers to the syndromes with "MEN" in their name, plus the entity of familial medullary thyroid cancer (FMTC).

MEN syndromes are inherited as autosomal dominant disorders.

MEN 2B was transiently known as MEN 3 in the 1970s, but that term is no longer used. An early report was Schimke et al in 1968.[3]

In November 2007, cardiologist John G. Sotos announced his hypothesis that Abraham Lincoln, the 16th President of the United States (1861–1865), had MEN 2B.[4][5]
