Figure 3
(a) H&E staining (4x): fine needle thyroid biopsy contained an admixture of diffuse chronic lymphocytic infiltration and dense fibrous tissue with a total absence of thyroid follicles. (b) H&E staining (20x): thyroid gland with capsule easily dissociable from the periglandular tissues and follicular cells in squamous metaplasia; (c),(d) H&E staining (20x): thyroid tissue with residual follicles immersed in dense fibrotic stroma and surrounded by diffuse chronic lymphocytic inflammation.
