====Micro==== | |||
The section shows a well-circumscribed lesion encapsulated by a thick fibrous capsule (~0.4 mm thick). | |||
The lesions consists of microfollicles with a dense appearing colloid. The nuclei have round regular nuclear membranes. Small indistinct nucleoli are seen at high power. | |||
Focally, the lesional cells overlap. However, the chromatin is not cleared. Nuclear grooves are not readily apparent and nuclear pseudoinclusions are not readily identified. | |||
