Is multiple endocrine neoplasia an autoimmune disease?

Abstract. Autoimmune Addison’s disease (AAD) is a rare condition occurring either in isolation or associated with other autoimmune diseases as part of an autoimmune polyglandular syndrome (APS) type 1, 2 or 4. Multiple endocrine neoplasia (MEN) type 1, 2 or 4 is a hereditary autosomal dominant cancer syndrome.

When does multiple endocrine neoplasia occur?

Multiple endocrine neoplasia syndromes can appear in infants or in people as old as age 70. These syndromes are usually inherited. The tumors and the abnormally large glands often produce excess hormones.
