An Advanced Concept in Thyroid Cytology with Special Emphasis on Ancillary Techniques

Thyroid Fine needle aspiration cytology(FNAC)has gone through a paradigm shift approach towards thyroid lesions. The 2017 Bethesda classification has helped to redefine the various conditions of the thyroid.

The objective of:

The study was to observe the importance of using Bethesda system of reporting of the various categories.
To study the utility of ancillary techniques, mlbc cell block in thyroid .
To emphasize the use of special stains in thyroid
An attempt has been made to utilize the classification with an example in each category. A total of 274 cases were studied over a period of one year (2018) from January to December) at a tertiary referral hospital. The majority of cases were non neoplastic accounting to 246 cases with neoplastic cases accounting for 28 cases.

The other ancillary techniques like use of Agnors, Morphometric, Pattern analysis, Cell block, ICC (immunocytochemistry) with LBC (Liquid based cytology) have been highlighted. Brief mentions of molecular techniques and recent advances, new concepts like NIFTP have been discussed to highlight the irutilityin surgical management of Thyroid.
