			- LYMPHOCYTIC THYROIDITIS.
			- NODULAR HYPERPLASIA.
			- NEGATIVE FOR MALIGNANCY.
			</pre>

			===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.
