Oxyphilic cells are located predominantly in compact cell groups. The
presence of groove in a great proportion of cells might raise the
possibility of a carcinoma although this property has a limited
significance in the case of Hürthle-cells.
|
The high cellularity and the presence of papillary clusters are signs
favouring malignancy. Nevertheless the lack of dissociated cells and
intranuclear inclusions and grooves argue against the possibility of a
carcinoma.

The presence of a halo sign and perinodular blood flow is very specific
sign of a follicular tumor. Moreover, the nodule is echonormal which
would be an extremely rare presentation of a thyroid carcinoma.
|
The nodule is hypoechogenic and does not display a halo sign but has
perinodular blood flow. These properties favour the possibility of a
follicular tumor.

Taking the sonographic and cytological data into account, we gave the
diagnosis of a Hürthle-cell tumor.
|
Taking the sonographic and cytological data into account, we gave the
diagnosis of a Hürthle-cell tumor with greater than the average
risk of malignancy. |
|
The combination of cytological and sonographic porperties prevented the
patient from an unnecessary operation.
|
The combination of cytological and sonographic porperties led to
intraoperative histological examination which resulted in papillary
carcinoma. Therefore the patient could be avoided of reoperation.
