What Histological Features are Associated with DIT?
Histologically, the thyroid follicles containing DIT can be observed using various staining techniques. The colloid within the follicles, rich in thyroglobulin, can be stained with periodic acid-Schiff (PAS) reagent, which highlights the presence of carbohydrates in thyroglobulin. In addition, immunohistochemistry can be used to specifically detect thyroglobulin and other thyroid-related proteins to study the distribution and abundance of DIT within the thyroid tissue.
