Parathyroid hyperplasia is a common cause of hyperparathyroidism that is often associated with chronic renal failure.[1]
General
- Common cause of hyperparathyroidism.
- Usually associated with chronic renal failure.
- May be syndromic - chief cell hyperplasia - associated with MEN 1, MEN 2A.[2]
Gross
- Classically all parathyroid glands are involved; however, some may be spared making it difficult to differentiate this from parathyroid adenoma.[3]
Microscopic
Features:[3]
- Classically have abundant adipose tissue.
- +/-Water-clear cells ("water-clear cell hyperplasia").
Note:
- Generally, it is impossible to discern between parathyroid adenomas and parathyroid hyperplasias by histology alone.[4]
- One requires information of the size of the other glands to make the diagnosis.
DDx:
- Parathyroid adenoma - classically have a rim of normal parathyroid gland around it.
