Characteristic cytological properties

Benign hyperplastic nodule - Case 17


Colloid in the background. Hyperplastic papillary fragments and naked pycnotic hyperchromatic dissociated nuclei - these are the most important cytological sign of a benign colloid goiter.

Benign hyperplastic nodule - Case 55

There is no colloid in the background. Moreover, there is a microfollicular growth pattern and follicular cells display oxyphilic changes. Nevertheless the hyperplastic papillary structures and the lack of prominent nucleoli and nuclear atypia stands against the possibility of a thyroid tumor.
