Multiple endocrine neoplasia overview

Overview
Multiple endocrine neoplasia (MEN) (or "multiple endocrine adenomas", or "multiple endocrine adenomatosis" -- "MEA") consists of three syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. 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. MEN syndromes are inherited as autosomal dominant disorders. Medullary carcinoma of the thyroid may occur as an autosomal dominant in the absence of other features.
