Autopsy
Optionally for a comprehensive autopsy, or where there is suspicion of parathyroid pathology, an effort is made to find the parathyroid glands, and inspect them for general or focal hyper-/neoplasia.
Microscopic evaluation
Look for the most common significant findings, which are:
- Hyperplastic glands, often nodular and asymmetric on inspection, and microscopy frequently show increased number of oxyphil cells.[1]
- Parathyroid adenoma.[1]
Serum calcium levels are generally elevated in patients with adenomas or hyperplastic glands containing large nodules, and often correlates with nephrosclerosis.[1]
Location and histology of the parathyroid glands
Parathyroid chief cell hyperplasia: An increase in the parenchymal cell mass,as a result of the proliferation of chief cells, oncocytes, and transitional oncocytes in multiple parathyroid glands.[2]
Parathyroid adenoma, histology
Parathyroid adenoma, fine needle aspiration
Parathyroid venous congestion in circulatory failure.

Microscopy report
Normal example:
- Sections show <<1, 2, 3, 4>> parathyroid glands with no focal changes or signs of hyperplasia.
