Learn About Parathyroid Adenoma

What is the definition of Parathyroid Adenoma?

A parathyroid adenoma is a noncancerous (benign) tumor of the parathyroid glands. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland.

What are the alternative names for Parathyroid Adenoma?

Hyperparathyroidism - parathyroid adenoma; Overactive parathyroid gland - parathyroid adenoma; Osteoporosis - parathyroid adenoma; Bone thinning - parathyroid adenoma; Osteopenia - parathyroid adenoma; High calcium level - parathyroid adenoma; Chronic kidney disease - parathyroid adenoma; Kidney failure - parathyroid adenoma

What are the causes of Parathyroid Adenoma?

The parathyroid glands in the neck help regulate calcium absorption, use, and removal by the body. They do this by producing parathyroid hormone, or PTH. PTH helps regulate calcium, phosphorus, and vitamin D levels in the blood and bone. It is important for healthy bones.

Parathyroid adenomas are common. Most parathyroid adenomas do not have an identified cause. Sometimes a genetic problem is the cause. This is more common if the diagnosis is made when you are young.

Parathyroid adenomas may occur in people without a family history of the disease, or as part of 3 inherited syndromes:

  • Multiple endocrine neoplasia (MEN) I
  • Multiple endocrine neoplasia (MEN) IIA
  • Isolated familial hyperparathyroidism

In people with an inherited syndrome, a changed (variant) gene is passed down through the family. You only need to get the gene from one parent to develop the condition.

  • In MEN I, problems in the parathyroid glands occur, as well as tumors in the pituitary gland and pancreas.
  • In MEN IIA, overactivity of the parathyroid glands occurs, along with tumors in the adrenal or thyroid gland.

Conditions that stimulate the parathyroid glands to get bigger can also cause an adenoma. These include:

  • Genetic disorders
  • Taking the medicine lithium
  • Chronic kidney disease

Women over age 60 have the highest risk for developing this condition. Radiation to the head or neck also increases the risk.

What are the symptoms of Parathyroid Adenoma?

Many people have no symptoms. The condition is often discovered when blood tests are done for another medical reason.

Parathyroid adenomas are the most common cause of hyperparathyroidism (overactive parathyroid glands), which leads to an increased blood calcium level. Symptoms may include any of the following:

  • Confusion
  • Constipation
  • Lack of energy (lethargy)
  • Muscle pain
  • Nausea or decreased appetite
  • Urinating more often at night
  • Weak bones or fractures

What are the current treatments for Parathyroid Adenoma?

Surgery is the most common treatment, and it often cures the condition. But, some people choose to only have regular checkups with their health care provider if the condition is mild.

To help improve the condition, your provider may ask you to stop taking calcium and vitamin D supplements. Women who have gone through menopause may want to discuss treatment with estrogen or other medicines to prevent bone loss.

What is the outlook (prognosis) for Parathyroid Adenoma?

When treated, outlook is generally good.

What are the possible complications of Parathyroid Adenoma?

Osteoporosis and the increased risk for bone fractures is the most common concern.

Other complications are less common, but may include:

  • Calcium deposits in the kidneys that can reduce kidney function (nephrocalcinosis)
  • Softened, weak areas in the bones (osteitis fibrosa)

Complications from surgery include:

  • Damage to a nerve that controls your voice
  • Damage to the parathyroid glands, which causes hypoparathyroidism (lack of enough parathyroid hormone) and low calcium level
When should I contact a medical professional for Parathyroid Adenoma?

Contact your provider if you have symptoms of this condition.

What are the latest Parathyroid Adenoma Clinical Trials?
Prospective Comprehensive Molecular Analysis of Endocrine Neoplasms

Background: * Endocrine neoplasms (tumors) are among the fastest growing tumors in incidence in the United States. Furthermore, it is often difficult to distinguish between benign or malignant tumors in cancers of the thyroid, parathyroid, adrenal gland, and pancreas. More research is needed to improve detection and treatment options for patients who develop these kinds of cancer. * Researchers are interested...

Do PTeye Score Correlate With Biochemical Markers in Parathyroid Adenoma?

Summary: Identifying the parathyroids is compulsory for success of parathyroidectomy for parathyroid adenoma. Near-infrared autofluorescence devices have been proposed as useful intraoperative tools for the identification of parathyroid glands. The aim of the present study is to evaluate the correlation of PTeye autofluorescence device with biochemical data of parathyroid adenoma patients.
