Clinical presentation: A 55-year-old man requested an evaluation after his twin-brother was diagnosed with papillary carcinoma. He had no complaints.

Palpation: Both lobes were a bit firm on palpation. There was a not firm nodule in the right lobe.

Laboratory tests: TSH 5.53 mIU/L, FT4 13.1 pM/L, aTPO 206 U/mL.

Ultrasonography. The thyroid was echonormal and presented numerous hypoechogenic discrete areas. One of them located in the upper part of the right lobe had punctate echogenic foci and was aspirated. There was an echonormal nodule in the middle-lower part of the right lobe. This lesion displayed halo sign and perinodular blood flow.

Cytology was performed form the lesion in the upper part of the right lobe and resulted in suspicion of papillary carcinoma.

Total thyroidectomy was performed. Histopathology: The echonormal nodule proved to be a hyperplastic nodule. Hashimoto's thyroiditis was found elsewhere in the lobe even in the lesion held suspicious on cytology.
