Abstract
Analysis of intraoperative air-dried imprints or smears of 20 cases of parathyroid adenoma revealed that the cells of the parathyroid adenomas did not contain extra- or intracellular lipid, but the cytologic material from accompanying normal or atrophic parathyroid glands had large amounts of intracellular lipid and variable amounts of extracellular lipid. Thus, rapid intraoperative cytologic preparation is not only effective in determining whether the specimen is parathyroid or not, but also in specifying the nature of the individual parathyroid glands. These observations again confirm that intraoperative cytologic evaluation of parathyroid tissue is an effective and important pathologic consultation method during parathyroid exploration.
