Normal thyroid follicles are replaced by two types of abnormal follicles:


* Hypertrophic follicles
* Hypertrophic follicles
* Follicles with resorption vacuoles
* Follicles with resorption vacuoles


The follicular cells of the hypertrophic follicles are hypertrophic (large). These follicles have no visible lumen or colloid substance.
The follicular cells of the hypertrophic follicles are hypertrophic (large). These follicles have no visible lumen or colloid substance. Due to the hyperactivity of the thyroid follicular cells these cells will quickly consume colloid. This leaves behind small “vacuoles” that line the follicular cells. It looks like the follicular cells “take a bite” out of the colloid substance.
