We studied ninety cases of thyroid glands both histopathologically and by immunohistochemical methods in patients with Graves' disease using B and T cell markers to evaluate the role of lymphocytic subpopulation. Females were affected more frequently than males with a ratio of 6.5:1, and usually the females were younger than the males at the time of surgery. The heavier the lymphocytic infiltration, the higher was the percentage of germinal center formation or fibrosis. The degree of lymphocytic infiltration was also related to the titers of antithyroglobulin or antimicrosomal antibodies. T cells were mostly scattered individually or in small groups between the follicles; however, in the severely infiltrated group, the major pattern was in clusters. T8 positive cells were more abundant than T4 positive cells, and their distribution pattern was accordant with T11 positive cells. Immunoglobulin synthesizing B cells were positively stained in 47 of 94 cases tested and IgG was the most predominant. In the mild and moderate lymphocytic infiltration groups, IgM was mostly stained at the mantle zone or in the lymphoid cluster of the interfollicular stroma, whereas IgM positive cells were present exclusively in the germinal center of the severely infiltrated group. The results of our study indicate that the major lymphocyte subpopulation in Graves' disease is B lymphocytes, and the degree of T lymphocytic infiltration correlated better with titers of antimicrosomal antibody than antithyroglobulin.

OBJECTIVETo explore the role of natural killer T (NK T) cells in the pathogenesis of Graves' disease.
METHODSNK T cell deficient mice and wild BALB/c mice were immunized with cells expressing TSH receptor once every two weeks 6 times. Two weeks after the final immunization, the mice were killed and serum thyroxine levels, anti-TSH receptor antibodies and thyroid pathological changes were examined.
RESULTSThe mean levels of TT(4) and TRAb in the immunized NK T cell deficient group were slightly elevated but significantly different from those of the non-immunized control group, while comparable to those in the immunized wild group. There were no significant changes of the activity levels of TSAb or TSBAb in the immunized NK T cell deficient mice compared to those in immunized wild control mice. Thyroids from immunized NK T cell deficient mice showed mild hypertrophy of some follicles as compared with non-immunized control mice. This change was comparable to immunized wild control mice.
CONCLUSIONNK T cells may not be involved in the pathogenesis of Graves' disease.

Most of thyroid lymphomas are B-lineage, and T-cell lymphomas are rare. Here, we report a case of primary thyroid T-cell lymphoma associated with Hashimoto's thyroiditis. A 48-yr-old woman presented with incidentally found neck mass. Histologically, the resected right lobe of the thyroid was replaced by monomorphic small atypical lymphoid cells with lymphoepithelial lesion-like change, most of which were immunoreactive for CD3, CD8, betaF-1, and TIA-1. Peripheral T-cell lymphoma, unspecified, was finally diagnosed after molecular study for TCR-gamma gene rearrangement. This is the second case of cytotoxic T-cell lymphoma reported in the thyroid gland so far. Unique association between thyroid follicles and neoplastic lymphocytes may be characteristic feature of this type of T-cell lymphoma.

Radioiodine activity required for remnant thyroid ablation is of great concern, to avoid unnecessary exposure to radiation and minimize adverse effects. We investigated clinical outcomes of remnant thyroid ablation with a low radioiodine activity in Korean patients with low to intermediate-risk thyroid cancer. For remnant thyroid ablation, 176 patients received radioiodine of 1.1 GBq, under a standard thyroid hormone withdrawal and a low iodine diet protocol. Serum levels of thyroid stimulating hormone stimulated thyroglobulin (off-Tg) and thyroglobulin-antibody (Tg-Ab), and a post-therapy whole body scan (RxWBS) were evaluated. Completion of remnant ablation was considered when there was no visible uptake on RxWBS and undetectable off-Tg (<1.0 ng/mL). Various factors including age, off-Tg, and histopathology were analyzed to predict ablation success rates. Of 176 patients, 68.8% (n = 121) who achieved successful remnant ablation were classified into Group A, and the remaining 55 were classified into Group B. Group A presented with significantly lower off-Tg at the first radioiodine administration (pre-ablative Tg) than those of Group B (1.2 +/- 2.3 ng/mL vs. 6.2 +/- 15.2 ng/mL, P = 0.027). Pre-ablative Tg was the only significant factor related with ablation success rates. Diagnostic performances of pre-ablative Tg < 10.0 ng/mL were sensitivity of 99.1%, specificity of 14.0%, positive predictive value of 71.1%, and negative predictive value of 87.5%, respectively. Single administration of low radioiodine activity could be sufficient for remnant thyroid ablation in patients with low to intermediate-risk thyroid cancer. Pre-ablative Tg with cutoff value of 10.0 ng/mL is a promising factor to predict successful remnant ablation.
