What is the difference between MEN1 and MEN2?

MEN1 syndrome usually causes tumors in the pituitary gland, parathyroid gland, or pancreas. MEN2 syndrome usually causes tumors in the thyroid gland, parathyroid gland, or adrenal gland. The tumors may be benign (not cancer) or malignant (cancer).

How do you know if you have MEN1?

MEN1 is diagnosed by genetic testing the MEN1 gene can be screened for mutations. This test is offered to people who have the clinical manifestations of MEN1 (diagnostic testing), or to the relatives of people known to have MEN1 (predictive testing).

Is there a cure for endocrine neoplasia?

No cure is known for any of the multiple endocrine neoplasia syndromes. Doctors treat the changes in each gland individually. A tumor is treated by removing it surgically when possible.

What are 3 types of endocrine disorders?

Types of Endocrine Disorders

  • Adrenal insufficiency. The adrenal gland releases too little of the hormone cortisol and sometimes, aldosterone. …
  • Cushing’s disease. Overproduction of a pituitary gland hormone leads to an overactive adrenal gland. …
  • Gigantism (acromegaly) and other growth hormone problems. …
  • Hyperthyroidism.

What are the symptoms of multiple endocrine neoplasia?


  • Tiredness.
  • Bone pain.
  • Broken bones.
  • Kidney stones.
  • Ulcers in the stomach or intestines.

Is MEN1 or MEN2 more common?

There are many forms of MEN, with the most common being type 1 and type 2. Multiple endocrine neoplasia type 1 and type 2 are rare, with each subtype affecting up to one in 30,000-35,000 people. Risk for MEN is similar in men and women and does not differ among people of different geographic or racial/ethnic groups.

What organs are affected by multiple endocrine neoplasia?

A rare, genetic disorder that affects the endocrine glands and can cause tumors in the thyroid gland, parathyroid glands, and adrenal glands.

How do you treat MEN1?

Surgical removal of the tumor is the treatment of choice. Unresectable tumors can be treated with diazoxide or octreotide. Chemotherapeutic agents or hepatic artery embolization has been used to treat metastatic disease. Insulinomas are most often single, large tumors that can be enucleated.

How do you test for MEN2?

What are the screening options for MEN2?

  1. Yearly blood tests for ionized calcium and parathyroid hormone levels, beginning in childhood (for people with MEN2A)
  2. Yearly blood tests for catecholamines and catecholamine metabolites (metanephrine and normetanephrine), beginning in childhood (for people with MEN2A and MEN2B)

Multiple Endocrine Neoplasia

Multiple endocrine neoplasia is a group of disorders that affect the body’s network of hormone-producing glands called the endocrine system. Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body.

Is Multiple Endocrine Neoplasia a rare disease?

Multiple endocrine neoplasia type 2 (MEN type 2) is a rare genetic disorder characterized by tissue overgrowth or tumor formation in various endocrine glands including the thyroid, the adrenal glands and the parathyroid.

Can you have MEN1 and MEN2?

The multiple endocrine neoplasias (MEN1, MEN2) are rare disorders involving germline inactivation/mutation of different genes (MEN1, RET). It is even more rare to find features of MEN1 and MEN2 both in one patient, with genetic mutation of only one, but not both, genes involved.

What is multiple endocrine neoplasia type 3?

Multiple endocrine neoplasia type III (MEN 3), also known as MEN 2b, is a syndrome that may be recognized at a young age by its characteristic numerous mucosal neuromas and marfanoid habitus.

Is multiple endocrine neoplasia fatal?

Multiple endocrine neoplasia typically involves tumors (neoplasia) in at least two endocrine glands; tumors can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumors become cancerous, the condition can be life-threatening.
