Correlations between the Presence of Hurthle Cells and Cytomorphological Features of Fine-Needle Aspiration Biopsy in Thyroid Nodules

INTRODUCTION: The presence of Hürthle cells (HC) in fine needle thyroid biopsy (FNAB) is a real concern for a cytologist and also for an endocrinologist. We aimed to demonstrate if the presence of HC is associated with specific cytological features in FNAB results. MATERIAL AND METHODS: This retrospective study analyzed 89 patients diagnosed with thyroid nodules, with FNAB; were two groups of patients: the study group A (HC+) (22 patients) with HC and control group B (HC-) (67 patients) with no HC; for both groups we analyzed the presence of 9 cytomorphologic features: overall cellularity, background colloid, lymphocyte infiltration, chronic inflammation, large nucleoli, small nucleoli, syn…
