A 44 year-old male patient was undergoing diagnosis and therapy for acute myelogenous leukemia (AML, M2). On physical examination a thyroid mass was palpated in the left lower lobe. He had palpitation and intolerance to heat. Thyroid function tests revealed hyperthyroidism; T3: 150ng/dl (N:60-90), fT4: 2.26 ng/dl (N:0.70-1.80), TSH: 0.01 ulU/ml (N:0.25-5.00). Ultrasonography demonstrated a hypoechoic mass with scattered calcifications measuring 2.55 2.03 3.64 cm in size. F-18 FDG camera-based PET scan performed as a follow-up study of AML revealed a focal increased uptake in the left neck, where an autonomous nodule was detected on Tc-99m thyroid scan. After the diagnosis of toxic autonomous nodule, Goetz disease, he underwent surgical nodulectomy. Microscopically, the nodule contained follicular proliferation with degenerative change but without evidence of thyroid carcinoma. Focal uptake in autonomous thyroid nodules is due to increased glycolysis within the nodules.

Subclinical hypothyroidism is defined as a normal serum free thyroxine level combined with an elevated thyroid stimulating hormone level. The causes of subclinical hypothyroidism are the same as those of overt hypothyroidism. There is good evidence that subclinical hypothyroidism is associated with progression to overt disease. The management of subclinical hypothyroidism is remains controversial. Patients with a serum thyroid stimulating hormone level greater than 10 mU/L have a higher incidence of elevated serum low-density lipoprotein cholesterol concentrations; however, evidence is lacking for other associations. There is insufficient evidence that hormone treatment of subclinical hypothyroidism is beneficial. The use of thyroid stimulating hormone level lone as a diagnostic and assessment tool for hypothyroidism is inadequate because this test cannot identify numerous conditions this sentence is unclear in its meaning. Using an expanded list of clinical signs and symptoms associated with dysfunction of the Hypothalamus-Pituitary-Thyroid axis, it is possible to hypothesize that subclinical hypothyroidism may be more common in a population of patients with early signs of age-related diseases than most practitioners realize. To improve thyroid function in subclinical hypothyroidism patients, practitioners should become familiar with foods and nutrients that can hinder or support thyroid function.

The thyroid nodules are the most common endocrine disease requiring surgical management. Up to date, various diagnostic techniques and surgical management have been developed. Authors analysed 2285 cases of thyroid nodules who were treated at Department of Surgery, Pusan National University for the duration of 10 years from January 1980 to December 1989 and the results obtained were summerized as follows: 1) Patients were composed of 1727 cases(75.8%) of benign nodule and 558 cases(24.5%) of malignant nodule. Benign nodule was prevalent in forth and fifth decade comparing with malignant nodule was sixth and fifth decade. The sexual distribution revealed female preponderance with 1:10.8 in benign nodule and 1:9.3 in malignant nodule. 2) The histopathologic classfication of benign nodule in decreasing order of frequency were follicular adenoma 1009 cases(54.8%), adenomatous goiter 573 cases(33.3%), simple cyst 65 cases(3.8%), and Hashimoto's thyroiditis 52 cases(3.0%). The malignant disease were papillary adenocarcinoma 460 cases(82.4%), follicular adenocarcinoma 69 cases(12.4%), undifferentiated carcinoma 13 cases (2.0%), and medullary carcinoma 7 cases(1.0%). 3) Fine needle aspiration cytology was performed in 1758 cases and it showed 80.5% of sensitivity, 96.5% of specificity, 19.5% of false negative and 80% of accuracy. 4) The location of nodule was 87.7%, in unilateral, 12.2% in bilateral. 5) On the radioiodine scanning, the incidence of benign nodule with cold nodule was 83.9% and the incidence of benign nodule with hot nodule was 7.5%. The incidence of thyroid carcinoma with cold nodule was 88.3% and the incidence of thyroid carcinoma with hot nodule was 4.6%. 6) Most cases of benign nodules were treated with lobectomy 82.6%, subtotal thyroidectomy 10.1% and subtotal lobectomy 3.0%. Malignant nodules were treated with lobectomy and/or isthmusectomy 37.6%, total thyroidectomy 17.7%, subtotal thyroidectomy 15.4%, and any thyroidectomy and neck dissection 13.5%. 7) Postoperative complications were developed in 3.8% of benign nodules and 13.8% of malignant nodules.

Objectives: This study aimed to characterize the histopathological pattern of thyroid lesions among Saudi patients and to highlight the age and gender variations of these lesions as base line data. Materials and Methods: We retrospectively analyzed the data from thyroid specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. Results: The 292 thyroidectomy specimens received during the study period came from 230 (78.8%) females and 62 (21.2%) males giving a female: male ratio of 3.7:1. Age of the patients ranged from 14 to 95 years with a mean age 39.7 years. Two hundred and eleven (72.3%) cases were found to be non-neoplastic and 81 (27.7%) cases were neoplastic. The non-neoplastic group included: colloid goiter, including both diffuse and nodular goiter (170 cases; 58.2%), nodular hyperplasia (28 cases; 9.6%), Hashimoto/chronic lymphocytic thyroiditis (12 cases; 4.1%), and Grave's disease (1 case; 0.3%). In neoplastic lesions, there were 7 benign tumors and 74 malignant tumors. Among the benign tumors, 5 were follicular adenomas and 2 were Hurthle cell adenomas. Papillary carcinoma was the commonest malignant tumor accounting for 87.8% of all thyroid malignancies, followed by lymphoma, follicular carcinoma and medullary carcinoma. The size of papillary carcinoma was more than 2 cm in 40 cases (76.9%). Conclusions: Non-neoplastic thyroid lesions were more common than neoplastic ones. Colloid goiter was the most common lesion. Follicular adenoma was the commonest benign tumor and papillary carcinoma was the commonest malignant lesion. There appears to be a slightly increased trend of papillary carcinoma diagnosis, most being diagnosed at an advanced stage.

Graves disease (GD) is the most common cause of hyperthyroidism, accounting for more than 90% of cases in Korea. Patients with GD are treated with any of the following: antithyroid drugs (ATDs), radioactive iodine (RAI) therapy, or thyroidectomy. Most patients begin treatment with ATDs, and clinical guidelines suggest that the appropriate treatment period is 12 to 18 months. While RAI treatment and surgery manage thyrotoxicosis by destroying or removing thyroid tissue, ATDs control thyrotoxicosis by inhibiting thyroid hormone synthesis and preserving the thyroid gland. Although ATDs efficiently control thyrotoxicosis symptoms, they do not correct the main etiology of GD; therefore, frequent relapses can follow. Recently, a large amount of data has been collected on long-term ATDs for GD, and low-dose methimazole (MMZ) is expected to be a good option for remission. For the long-term management of recurrent GD, it is important to induce remission by evaluating the patient's drug response, stopping ATDs at an appropriate time, and actively switching to surgery or RAI therapy, if indicated. Continuing drug treatment for an extended time is now encouraged in patients with a high possibility of remission with low-dose MMZ. It is also important to pay attention to the quality of life of the patients. This review aimed to summarize the appropriate treatment methods and timing of treatment transition in patients who relapsed several times while receiving treatment for GD.

Objective: Graves' disease, the most common cause of primary hyperthyroidism, is a thyroid specific autoimmune disorder. When resistance to medication is shown in spite of long term therapy with anti-thyroid drugs, radioactive iodine therapy would be chosen in Western medicine. However, this therapy has often been reported to cause patients have hypothyroidism, thus requiring them to take levothyroxine for the rest of their lives. In this study, we evaluate the clinical efficacy and safety of Ahnjeonbaekho-tang (AJBHT) on patients with Graves' disease. Methods: We prescribed AJBHT for 3 months to two groups: patients who had been taking antithyroid drugs were administered AJBHT after discontinuing the antithyroid drugs ($Com-Tx{\rightarrow}Single-Tx$), and patients who had not been taking antithyroid drugs were started with AJBHT (Single-Tx) immediately. We evaluated the thyroidal function test (TFT) and visual analogue scale (VAS) for clinical symptoms for 3 months. Results: Serum T3 and fT4 were significantly decreased in both groups and remission rate of thyroidal hormones were significantly improved in the Single-Tx group. The clinical symptoms of palpitation, fatigue, and heat intolerance were significantly improved in both groups. In the safety analysis, all patients were in normal range of liver, renal function blood test and common blood count. Conclusion: From these results, we suggested that AJBHT was effective on TFT and clinical symptoms of Graves' disease. The study supports that AJBHT may be a useful agent for patients with Graves' disease who are resistant to antithyroid medication or radioactive iodine therapy, and for patients at first diagnosis.

Regardless of the prognostic factors in papillary thyroid cancer, such as sex, age, size of tumor, extent of disease, and distant metastasis, the prognosis of papillary thyroid cancer is sometimes difficult to predict from clinical and microscopic analysis alone and additional prognostic indicators are needed. Recent studies of thyroid cancer have indicated that DNA aneuploidy may be correlated to the biological behavior of malignancy and inversely correlated to the prognosis, but it still remains contraversal. We performed this study to assess DNA ploidy patterns in relation with the previously known prognostic factors in AMES scoring system and lateral neck node metastasis in papillary thyroid cancer. A series of 132 patients with papillary thyroid cancer and 80 patients with benign thyroid tumor(27 follicular adenomas and 53 adenomatous goiters) as a control group from October 1993 to Feburary 1995 were analyzed and their nuclear DNA content was measured with flow cytometry using fresh tissue specimens. DNA aneuploidy was found in 8(6.1%) in papillary cancer and 8(10%) in benign tumor. S-phase traction(SFP) and proliferative index(PI) were higher in thyroid cancers, being 2.18$\pm$4.24%, 6.34$\pm$4.94% in the papillary thyroid cancers and 1.97$\pm$2.93%, 4.44$\pm$3.80% in the benign tumors, respectively. However there was no significant difference of values between two groups(p>0.05). Among variable prognostic factors studied(age, sex, size of tun or, extent of disease, distant metastasis in AMES scoring system and lateral neck node metastasis), DNA aneuploidy was found to be common in distant metastasis(p<0.001) and in lateral neck node metastasis(p>0.035), but there was no significant difference between the high risk and low risk group according to the AMES scoring system(p<0.08). In our study, DNA aneuploidy was not valuable in determining the presence of malignancy and did not correlate to the AMES scoring system. However, follow-up study of more cases will be needed for accurate information about the DNA ploidy as a independent prognostic factor.

Objectives: Three classic treatment modalities have been used to treat Graves' disease: antithyroid medication, radioiodine ablation, and subtotal thyroidectomy. Postoperative thyroid functions were studied in patients with Graves' disease treated by subtotal thyroidectomy to evaluate the superiority of surgical treatment. Materials and Methods: One hundred fourty patients of Graves' disease were analysed retrospectively in follow-up for more than three years following subtotal thyroidectomy. Postoperative serum levels of $T_3,\;T_4, TSH, TSH-R Ab, free $T_4$, were evaluated to watch hypo- or hyperthyroidsm. Results: In the evaluation of preop- and postoperative thyroid function after three years of subtotal thyroidectomy, $T_3$ was changed from $464.10{\pm}196.16ng/dl$ to $140.41{\pm}76.56ng/dl$ in mean value, $T_4$ was changed from $20.76{\pm}7.98{\mu}g/dl$ to $9.54{\pm}4.02{\mu}g/dl$, $TSHT_3$ was changed from $0.55{\pm}4.42{\mu}u/ml$ to $4.96{\pm}7.20{\mu}u/ml$, TSH-R Ab was changed from $41.6{\pm}28.27%$ to $28.7{\pm}28.79%$ and free $T_4$ was changed from $4.45{\pm}2.33ng/dl$ to $1.44{\pm}0.69ng/dl$ in mean value. Euthyroidism was noted in 118 patients(84.3%), overt hyperthyroidism in 6 patiens(4.3%), latent hyperthyroidism in 8 patients(5.7%), overt hypothyroidism in 2 patint(1.4%), and latent hypothyroidism in 6 patients(4.3%). Of surgical complications, permanant hypoparathyroidism was found in one patient, recurrent laryngeal nerve injury in two patients, postoprative bleeding with reoperation in two patients, and death in one patient. Conclusion: The thyroid function after subtotal thyroidectomy in diffuse toxic goiter is normal level (euthyroidism) in 84.3% and low recurrence rate of hyperthyroidism is showed with rare surgical complication. Therefore, subtotal thyroidectomy in diffuse toxic goiter is more effective and safe than RI or longterm ATD treatment, if the operation is performed by skillful surgeon.
