Summary

Description
English: Intermediate magnification micrograph of the parathyroid gland. H&E stain. Excised surgically for parathyroid adenoma - not seen on image.


Cells of the parathyroid:

  • Parathyroid chief cells - intense hyperchromatic to eosinophilic cytoplasmic staining (see notes), abundant in number, moderate amount of cytoplasm, function - manufacture PTH.
  • Oxyphil cells - moderate/light hyperchromatic to eosinophilic, rare, abundant amount of cytoplasm, function - not known.
  • Adipocytes - seen in older people, increases with age.


Notes:

  • Cytoplasmic staining varies considerably on H&E preparations - it may vary from hyperchromatic to clear to eosinophilic.
  • Chief cells tend to stain more intensely than oxyphil cells.
