Recognize thyroid histology by the presence of round follicles lined by a simple cuboidal epithelium and filled with colloid. The colloid pool inside these follicles is a hallmark of thyroid tissue, storing thyroglobulin for hormone production. The surrounding capillary-rich stroma and occasional parafollicular cells between follicles can also help, but the key clue is the colloid-filled follicles. In contrast, liver shows hempatic plates and sinusoids, pancreas shows acini and ducts (with islets of Langerhans in the endocrine part), and kidney shows glomeruli and tubules, none of which feature colloid-filled thyroid follicles.
