Clinical presentation: a 48-year old woman was referred for an evaluation of a nodule discovered by the GP on routine examination performed because of upper airways infection.

Palpation: a large nodule was palpable in the right lobe.

Hormonal examination indicated euthyroidism with TSH 1.16 mIU/L.

Ultrasonography revealed a solitary echonormal-minimally hypoechogenic nodule with halo sign and perinodular blood flow in the right thyroid.

Cytological report: follicular tumor with less than the average risk for malignancy. Surgery was performed.

Histopathological diagnosis: minimally invasive follicular cancer.

Comment: there were only a few follicles on the smear. Taken the sonographic picture into account, the cytological diagnosis was not difficult. This is one of our very few cases where a carcinoma was found in an almost echonormal nodule.
