The Correct Answer is E hyperplastic follicles, scanty colloid with "scalloping"
- Grossly, the thyroid gland is symmetrically enlarged.
- Histology of the thyroid gland reveals follicles lined with tall columnar cells with basally located nuclei.
- Colloid adjacent to epithelium appears vacuolated and scalloped.
- Some follicles contain almost no colloid.
- The stroma contains lymphocytes.
- The follicular epithelium often projects into the lumen of the follicles the form of small papillary infoldings.
The gland is heavily infiltrated with lymphocytes destroying normal thyroid architecture. Lymphoid follicles and germinal centers may be present. Follicular epithelial cells are frequently enlarged and contain basophilic cytoplasm (Hurthle cells).
