Spontaneous remission of primary hyperparathyroidism
Summary
Primary hyperparathyroidism (pHPT) involves high calcium and parathyroid hormone (PTH) levels, often due to adenomas. This case shows spontaneous remission of pHPT, with normal lab values and a resolved cervical mass.
Area of Science:
- Endocrinology
- Neoplasms
Background:
- Primary hyperparathyroidism (pHPT) is diagnosed by elevated serum calcium and parathyroid hormone (PTH) with low inorganic phosphate.
- Parathyroid adenomas are the most common cause of pHPT and are often detectable via ultrasound.
Observation:
- A 68-year-old man was diagnosed with primary hyperparathyroidism.
- The patient presented with a cervical mass suggestive of a parathyroid adenoma.
Findings:
- Two years post-diagnosis, the patient experienced spontaneous remission of pHPT.
- Laboratory results normalized, showing regular serum calcium and PTH levels.
- Ultrasound confirmed the disappearance of the cervical mass.
Implications:
- This case highlights the possibility of spontaneous remission in primary hyperparathyroidism.
- It suggests that observation may be a viable strategy in select pHPT cases.
- Further research into the mechanisms of spontaneous parathyroid adenoma regression is warranted.

00:59The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

01:21Skeleton and Calcium Homeostasis
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
