Chronic lymphocytic thyroiditis - Case 8 |

The cytology corresponded to chronic lymphocytic thyroiditis. Only a
few thyrocytes were found on the smear. They occurred mostly in
microfollicles. One of the latter is demonstrated in the last image.
|
The dominant cell type is a follicular cell and the dominant structure
is
microfollicle. Nevertheless, there are lymphocytes and nuclear debris
on the smear. Follicular tumor and lymphocytic thyroiditis have to be
considered.

The nodule presents a halo sign and perinodular blood flow, therefore
this lesion is a follicular tumor with more than 90% probability. Nevertheless, the extranodular part is hypoechogenic, therefore the patient harbors with great probability an autoimmune thyroiditis, too.
|
The thyroids are hypoechogenic so the presence of a lymphocytic
thyroiditis is evident. Regarding the hyperechogenic lesion, it does
not display either a halo sign or perinodular blood flow. Therefore it
is
unlikely that this lesion would be a follicular tumor.

|
Taking the cytological and sonographic
pattern into account, we gave a combined cytological-sonographic
diagnosis of Hashimoto's thyroiditis and suspicion of follicular
tumor with less than the average risk of carcinoma.
