On 4 March, a 49-year-old man was referred to the Fine Needle Aspiration (FNA) Clinic at our hospital for evaluation of a large thyroid nodule. Neck ultrasound revealed a normally positioned thyroid gland with a 6 cm hypoechoic nodular mass at the isthmus. An ultrasound-guided FNA was performed in collaboration with the interventional radiology team. Two smears were prepared and immediately fixed for Papanicolaou staining.
