A. The sections show thyroid gland with extensive fibrosis and lymphoid follicles, with well-developed germinal centres and tingible-body macrophages. Follicular cells show focal enlargement and nucleoli in association with a lymphoplasmic infiltrate. There is no nuclear clearing, no nuclear grooves and no nuclear pseudoinclusions. There is no evidence of malignancy. | |||
One focus of benign parathyroid tissue is present. There are three benign lymph nodes with sinus histiocytosis. The sinus histiocytes have round nuclei less than two times the size of a mature lymphocyte. | |||
