Neuroendocrine lesions of the thyroid are rare. The most common types are medullary thyroid carcinomas (MTCs) and C-cell hyperplasia. MTCs originate from thyroid parafollicular cells that secrete calcitonin which serves as a serum marker of MTCs. Here, the rare case of a calcitonin-negative neuroendocrine tumor (NET) derived from follicular lesions of the thyroid is described. A 34-year-old man presented at our hospital for the surgical management of an incidental thyroid nodule that was observed on an ultrasound sonography (USG) of the neck. Initially, USG-guided aspiration cytology was performed, and a MTC was suspected. The expressions of thyroglobulin and thyroid transcription factor-1, which are thyroid follicular cell markers, and synaptophysin and chromogranin A, which are neuroendocrine markers, was confirmed following surgical pathology. However, the staining of calcitonin, a marker of MTCs, was not observed. A nonmedullary NET of the thyroid is uncommon, and the distinction between calcitonin-negative NETs and MTCs of the thyroid may be important due to differences in their clinical courses and management.

A diagnostic whole-body scan (WBS) is recommended 6 to 12 months after total thyroidectomy and radioactive iodide ablation in intermediate- or high-risk patients with differentiated thyroid cancer (DTC). The aim of this study was to evaluate the necessity of a diagnostic WBS after radioactive iodide ablation in intermediate-risk patients with DTC.


A total of 438 subjects were included in the study: 183 low-risk subjects and 255 intermediate-risk subjects according to the American Thyroid Association guideline. All subjects diagnosed with DTC received 1,100 MBq (30 mCi) activity of radioiodine (I-131) following total thyroidectomy. On follow-up, all subjects underwent a diagnostic I-131 WBS after thyroid hormone withdrawal.


After initial radioactive iodide ablation, 95.1% of low-risk patients and 91.4% of intermediate-risk patients showed no uptake on diagnostic WBS (P=0.135). Intermediate-risk patients with stimulated thyroglobulin (Tg) levels higher than 2.0 ng/mL showed a greater rate of radioactive iodine uptake on diagnostic WBS. Four intermediate-risk patients showed recurrence during the 16 to 80 months follow-up period. Three of the four patients with recurrence showed no uptake on diagnostic WBS and had a stimulated Tg level less than 2.0 ng/mL.


A diagnostic I-131 WBS after radioactive iodide ablation in intermediate-risk patients with DTC may not be necessary. A large prospective study is necessary to determine the necessity of diagnostic WBS in intermediate-risk patients with DTC.

AbstractAbstract PDF
A pheochromocytoma is a neuroectodermal tumor that originates from the chromaffin cells of the sympathetic system. It has typical symptoms or signs, such as periodic attacks of paroxysmal hypertension, palpitation, headache, and sweating, related to an increased catecholamine secretion. Types of catecholamine secreted from tumors are usually norepinephrine and epinerphrine. There are a few reports of dopamine-secreting pheochromocytoma with absence of other catecholamines secretion. Here, we report the case of a 59-year-old man with dopamine-secreting pheochromocytoma, with no typical symptoms or signs.

AbstractAbstract PDF
Thyroid cancer is a common disease and its prevalence is increasing. Recent reports have shown that an elevated thyrotropin (thyroid stimulating hormone, TSH) level is associated with thyroid cancer risk. However, the association between TSH level and thyroid cancer risk is not yet known for euthyroid patients diagnosed with papillary thyroid microcarcinoma (PTMC). METHODS: Our study included 425 patients who underwent thyroid surgery and were diagnosed with PTMC between 2008 and 2009. Control group patients were diagnosed with benign nodules < or = 1 cm in size by US-guided fine needle aspiration. Nodules with one or more suspected malignant-ultrasonographic feature(s) were excluded from this study. Patients who were not euthyroid or who took thyroid medication were also excluded. RESULTS: The mean age of all patients was 48.5 +/- 11.0 years and 88.8% were women. The mean age of those with PTMC was significantly lower than that of the control group. The mean TSH level was 1.78 +/- 0.93 mIU/L, and the mean free T4 level was 15.96 +/- 2.32 pmol/L. There was no difference in TSH level between the PTMC and control groups (1.77 +/- 0.93 mIU/L vs. 1.79 +/- 0.91 mIU/L, P = 0.829). After adjusting for age, TSH level was not correlated with tumor size (r = 0.02, P = 0.678) in the PTMC group. Moreover, the TSH level did not differ between patients with stage I and stage III-IV carcinoma (stage I, 1.77 +/- 0.95 mIU/L; stage III-IV, 1.79 +/- 0.87 mIU/L; P = 0.856). CONCLUSION: TSH levels are not elevated in euthyroid PTMC patients. Thus, further evaluation is needed before serum TSH can be used as a tumor marker for small nodules < or = 1 cm in size in euthyroid patients.

AbstractAbstract PDF
Patients with pheochromocytoma manifest with headache, perspiration, and palpitation. Although most patients have either sustained or paroxysmal hypertension, some patients present with hypotension. However, severe orthostatic hypotension is relatively rare in patients with pheochromocytoma. We report here on a 72-year-old woman with pheochromocytoma and she presented with recurrent syncope due to hypotension and blood pressure fluctuation. Syncope due to hypotension is unusual in patients with pheochromocytoma and only a few such cases have been reported. The present case serves to illustrate an unexpected presentation of this tumor.

AbstractAbstract PDF
Familial isolated primary hyperparathyroidism (FIHP) is an autosomal dominant disorder that is characterized by an early stage of either multiple endocrine neoplasia type 1 (MEN1) or hyperparathyroidism-jaw tumor (HPT-JT) syndrome. We report here on a case of a 42-years old woman who was diagnosed with papillary thyroid cancer and primary hyperparathyroidism. Her younger brother also had primary hyperparathyroidism. On the genetic analysis, they were both proven to have a novel frameshift mutation in the MEN1 gene (exon 10).

AbstractAbstract PDF
Thyroid hormones play an important role in the regulation of lipid and carbohydrate metabolism and the body mass index (BMI), which all affect non-alcoholic fatty liver disease (NAFLD). In a previous study, we demonstrated that free T4 was negatively associated with the BMI in euthyroid women. However, there is still uncertain as to whether the thyroid function within the normal range is associated with NAFLD and liver function abnormalities. We sought to evaluate the thyroid function (free T4, TSH) and its possible relationship with NAFLD in euthyroid women. METHODS: A total of 835 euthyroid, non heavy alcoholics women who visited the Daegu Catholic University University Medical Centre for primary health screening from January 1, 2006 to December 31, 2006 participated in this cross-sectional study. The women who were not euthyroid or heavy alcoholics (> 70 g/week in women according to the DSM-IV), there was no known history of diabetes mellitus, the fasting blood glucose was more than 5.55 mmol/L and those who had viral hepatitis were excluded. Hepatic ultrasonography scanning was performed in all the participants by a single experienced radiologist. The TSH, free T4, BP, fasting glucose, serum liver enzymes (AST, ALT, GGT, T-bilirubin), lipid profiles [total-cholesterol, triglyceride (TG), HDL-C, LDL-C] and NAFLD were evaluated. RESULTS: Euthyroid women with NAFLD had lower free T4 levels than did the euthyroid women without NAFLD. After adjustment for age and BMI, free T4 was negatively correlated with TG, but free T4 was positively correlated with the total serum bilirubin. Free T4 was not correlated with the serum AST, ALT and GGT. After adjustment for age, the BMI, the fasting glucose, the GGT and free T4, but not TSH, were significantly negatively correlated with NAFLD. CONCLUSION: We demonstrated a negative correlation between free T4 and NAFLD in euthyroid women. This finding suggests lower levels of free T4 is associated with NAFLD in euthyroid subjects.

AbstractAbstract PDF
Central diabetes insipidus is a heterogeneous condition that is characterized by polyuria and polydipsia, and this is due to a deficiency of arginine vasopressin. Central diabetes insipidus is rare in children and young adults, and up to 50 percent of cases are idiopathic. Genetic abnormalities in the homeobox genes have recently been shown, on sellar magnetic resonance imaging, to be associated with combined pituitary hormone deficiency with pituitary defect. We report here on a 44-year-old female who suffered from polydipsia, polyuria and primary amenorrhea since childhood. She was diagnosed with idiopathic central diabetes insipidus together with primary empty sella and combined pituitary hormone deficiency. On the genetic analysis, she was proven to have a point mutation of the PROP-1 gene, which is known as a cause of combined pituitary hormone deficiency.

AbstractAbstract PDF
The accurate diagnosis of a thyroid nodule is important in deciding a patient's treatment plan and for predicting the prognosis. The histopathological diagnosis of resected specimens are largely positively accomplished, but the consistency of the diagnosis is low when the specimen shows a small carcinomatous cytological feature or the nodule does not express papillary proliferation. Therefore, the need for supplementary diagnostic measures is increased. Herein, the expressions of galectin-3 and thyroid peroxidase (TPO) of resected specimens were investigated using immunohistochemical staining, and their potential for contributing to an accurate diagnosis studied. METHODS: The specimens included 195 resected thyroid nodules obtained from 179 patients having undergone thyroid surgery. Immunohistochemical staining for two useful antibodies, galectin-3 and TPO, were performed, and the expressions of these two antibodies investigated with regard to the histological diagnosis. RESULTS: The sensitivity, specificity, and positive and negative predictive values of galectin-3 and TPO for detecting papillary carcinomas were all 100%, but these values were low for other forms of carcinoma. CONCLUSION: Our data showed the diagnosis of thyroid nodules, using immunohistochemical staining for galectin-3 and TPO, was very useful for detecting thyroid papillary carcinoma, but insufficiently sensitive for follicular carcinoma. Immunohistochemical staining for TPO is also useful for distinguishing cases when a false positive result for galectin-3 is obtained.

AbstractAbstract PDF
Pheochromocytoma arises from chromaffin cells of the paraganglionic system. Urinary bladder pheochromocytoma is very rare tumor that accounts for less than 0.06% of all urinary bladder tumors and it is less than 1% of all pheochromocytoma. Urinary bladder pheochromocytoma usually arises from the sympathetic nervous system of the bladder wall. Paroxysmal headache and palpitation precipitated by micturition are common specific symptoms of this tumor. The paroxysm commonly persists or the patients relapse in a few days or months. Herein, we report a case of urinary bladder pheochromocytoma with a long asymptomatic period.
