SUMMARY OF THE STUDY
A total of 143 indeterminate thyroid biopsy specimens were reviewed by experienced pathologists. Almost 25% were confirmed to actually be parathyroid tissue and not an indeterminate thyroid lesion. In these 34 parathyroid lesions, 3 different simple cytologic patterns were identified and there were many consistent cytologic features as well.
WHAT ARE THE IMPLICATIONS OF THIS STUDY?
The identification of parathyroid glands that are within the thyroid is often a challenge. This study identifies characteristics of what a parathyroid lesion looks like under the microscope and should help cytopathologists to consider that diagnosis for thyroid lesions they are determining to be indeterminate.
