Approach to Thyroid FNA Cytopathology: An Overview
In this book, we present a practical, algorithmic approach to the diagnosis of thyroid fine needle aspirations (FNAs) (Figure 3.1). This approach uses a combination of low-magnification assessment of cellular components, evaluation of cytoarchitectural patterns, and high-magnification scrutiny of nuclear features. This approach will also enable the placement of FNAs into diagnostic categories that have recently been developed from a National Cancer Institute (NCI) conference on thyroid FNA termed the Bethesda System for Reporting Thyroid Cytopathology (BSRTC).
