Clinical data: a 27-year-old man requested a second opinion. He was treated for hyperthyroidism for 6 months when ultrasonography was performed.

Palpation: both thyroids were enlarged and moderately firm. There was no palpable nodule.

Results of blood tests: hypothyroidism on daily 20 mg propylthiouracil (TSH 8.81 mIU/L, FT4 8.01 pM/L).


Cytology: was performed from the hyperechogenic nodule and resulted in suspicion of papillary carcinoma. (The two rows of cytological images represent two different smears.)

 

The lesion in question was found in the left lobe.
