Fine needle aspiration cytology of nodular thyroid lesions: a 2‐year experience of the Bethesda system for reporting thyroid cytopathology in a large regional and a university hospital, with histological correlation

Thyroid fine needle aspiration (FNA) contributes to the appropriate management of nodular thyroid lesions. The introduced categories in the Bethesda system for reporting thyroid cytopathology (TBSRTC) are associated with an implied cancer risk, providing a clinical management guideline. This study aims to evaluate the reproducibility of this implied risk and to compare the results from two different cytopathology departments.Five hundred...
