Overview
- There is no established system for the classification of [disease name].
OR
- [Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].
OR
- [Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3].
- [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].
OR
- Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.
OR
- If the staging system involves specific and characteristic findings and features:
- According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].
OR
- The staging of [malignancy name] is based on the [staging system].
OR
- There is no established system for the staging of [malignancy name].
Classification
Primary hyperparathyroidism
Primary hyperparathyroidism results from a hyperfunction of the parathyroid glands themselves. There is oversecretion of PTH due to adenoma, hyperplasia or, rarely, carcinoma of the parathyroid glands.
Secondary hyperparathyroidism
Secondary hyperparathyroidism is the reaction of the parathyroid glands to a hypocalcemia caused by other than a parathyroid pathology, e.g. chronic renal failure.
Tertiary hyperparathyroidism
Tertiary hyperparathyroidism is a state of excessive secretion of parathyroid hormone (PTH) after a long period of secondary hyperparathyroidism and resulting in hypercalcemia.
