The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is widely used for the standardized reporting of thyroid fine-needle aspiration (FNA) cytology. The 2023 revision of TBSRTC introduced specific subcategories for the classification of atypia of undetermined significance (AUS). This study tests the association between AUS subtypes and malignant diagnoses, namely AUSnuclear atypia and AUS-other, in archived thyroid – FNA specimens with atypia from 2018-2022 at King Abdulaziz University Hospital. A total of 104 thyroid – FNA specimens with AUS were re-evaluated cytologically and correlated with subsequent surgical outcomes, along with a discussion of discrepant cases

Keywords: Bethesda system, thyroid cytopathology, Atypia of Undetermined Significance, fine needle aspiration, papillary thyroid carcinoma, AUS-nuclear atypia, AUS-other.
