Detailed explanation-1: -Primary hyperparathyroidism occurs because of a problem with one or more of the four parathyroid glands: A noncancerous growth (adenoma) on a gland is the most common cause. Enlargement (hyperplasia) of two or more parathyroid glands accounts for most other cases.
Detailed explanation-2: -Parathyroid carcinoma is a rare cause of primary hyperparathyroidism, which is usually caused by a parathyroid adenoma and occasionally by primary parathyroid hyperplasia. Other rare causes are parathyroid cyst and ectopic secretion of parathyroid hormone (PTH) from a nonparathyroid tumor.
Detailed explanation-3: -Parathyroid adenomas are non-cancerous parathyroid tumours. They are the most common type of tumour that can develop in the parathyroid glands. A parathyroid adenoma usually forms in only one parathyroid gland.
