  • Congenital thyroid dysgenesis including agenesis, hypoplasia and ectopia is the predominant cause of permanent hypothyroidism. Of these, two thirds are due to an ectopic thyroid and about one third to complete thyroid agensis. From Jan. 1981 to Dec. 1992, authors experienced the 9 cases of congenital thyroid dysgenesis. Aberrent thyroid was 4 cases (44.4%), thyroid hemiagenesis with aberrent thyroid was 3 cases(33.3%) and thyroid hemiagenesis was 2 cases(22.2%). The most predominant site of aberrent thyroid is the base of tongue(85.7%). 7 patients(77.8%) revealed euthyroidism and among them, 4 patients showed elevated TSH level. Hypothyroidism was 2 patients (22.2%). 7 cases responded to thyroid suppressive therapy. 2 cases of lingual thyroid which did not responed to thyroid suppressive therapy underwent surgery and they have placed on thyroid suppressive therapy postoperatively.

  • A 47-year old woman was admitted to our hospital for removal of a known mass that was located on the suprasternal notch; specifically, the mass was located on the supero-anterior mediastinuum. The mass was removed by a cervical incision and the histopathologic diagnosis of the resected specimen was hererotopic thyroid tissue with nodular hyperplasia. Mediastinal hererotopic thyroid tissue is a rare malady, so we report here diastinal hererotopic thyroid tissue and we review the relevant medical literature.

  • 설갑상선은 주로 설맹공과 후두개사이에서 발생하는 일종의 이소성 갑상선으로서, 비교적 희귀한 질환으로, 1869년 Hickman이 처음으로 보고한 이래, 외국에서는 약 300례 정도의 보고가 있다. 최근 저자들은 48세 남자에서 정상 위치에 있어야 할 갑상선이 결여되고, 설갑상선 만이 있는 1례를 우연히 발견해서, 갑상선 scan 으로 확인할 수 있었기에 문헌적 고찰과 함께 보고하는 바이다.

  • Ectopic thyroid glands generally occur in the midline as a result of abnormal median migration, and their presence lateral to the midline is extremly rare. We report a 83-year-old male with anaplastic carcinoma admix papillary carcinoma in the extrathyroid area. We suspected left lateral neck metastasis on preoperative fine needle aspiration result and computed tomography. the patient underwent total thyroidectomy and left selective neck dissection(level II, III, IV, V). The patient was diagnosed as having an ectopic thyroid gland on the lateral neck with anaplastic carcinoma admix papillry carcinoma. The patient is alive without incident of tumor recurrence at 5month after surgery and radiotherapy.

  • Ectopic thyroid is an uncommon embryologic aberration characterized by the presence of thyroid tissue in a site other than its usual pre-tracheal location. Dual ectopic thyroid is extremely rare, only few cases have been reported in the literature. Physical examination, laboratory test and radiologic examinations are usually performed for the diagnosis and therapeutic plan of dual ectopic thyroid. We report a 36-year old female with dual ectopic thyroid in lingual and hyoid regions but without thyroid tissue in its normal area. The diagnosis was made through pathologic examination after surgical resection.

  • Purpose : Thyroid hormone is essential for development of the brain in early life. Thyroid dysfunction is more common in the first 2-4 postnatal weeks of life in premature infants than in term infants. This study aimed to identify the prevalence and clinical course of thyroid dysfunction in prematurity. Methods : Premature infants admitted to and given neonatal screenings at Dankook University Hospital between April 1999 and March 2008 were included in this study. We retrospectively reviewed medical records and categorized subjects into six groups: normal, hypothyroidism, hyperthyrotropinemia, hypothyroxinemia, delayed onset of hypothyroidism, and delayed onset of hyperthyrotropinemia. Results : Among 599 subjects, 136 (23%) had initially abnormal thyroid function test (TFT); transient hypothyroxinemia was the most frequent condition (118, 20%). In addition, 8 (17%) of 46 subjects with initially normal TFT levels showed delayed onset of hyperthyrotropinemia with or without low free thyroxine ($fT_4$). Thyroxine was prescribed for 10 patients (1.7%) due to low $fT_4$ levels but was discontinued in 9 patients during follow-up. Thyroid scan confirmed ectopic thyroid in one patient. Conclusion : Thyroid dysfunction was frequently seen in premature infants, but most of the conditions were transient. In addition, some infants showed delayed TSH elevation on routine follow-up. Therefore, a recheck of the thyroid function of premature infants at 3-4 weeks is recommended, even if normal thyroid function is initially seen, especially in prematurity of less than 33 weeks of gestational age or birth weight of less than 2,500 grams.

Simultaneous Elevation of Serum Parathyroid Hormone(PTH) and Parathyroid Hormone-related Protein(PTHrP) in a Case of Lung Cancer with Hypercalcemia (고칼슘혈증을 보인 폐암환자에서 부갑상선호르몬(PTH)과 부갑상선호르몬관련단백질(PTHrP)이 동시에 증가된 1예)

  • The parathyroid hormone related protein (PTHrP) is the most common causative peptide of humoral hypercalcemia of malignancy. In contrast, the serum level of parathyroid hormone (PTH) is low to undetectable in the majority of patients with malignancy associated hypercalcemia. Few cases exist in which the production and secretion of PTH by malignant nonparathyroid tumors have been authenticated. To our knowledge, there is very rare case in which a nonparathyroid tumor expressed simultaneously both the PTH and PTHrP. We report a case of squamous cell carcinoma of the lung with hypercalcemia which presented with simultaneous elevation of serum PTH and PTHrP. Severe hypercalcemia (serum calcium, 7.5 mEq/L) was found in a 65-year-old man who had a squamous cell carcinoma of the lung without any bony metastasis and detectable parathyroid abnormalities on isotope scintigraphy. The serum level of intact parathyroid hormone (PTH) con centration was markedly elevated as measured in two site radioimmunoreactive PTH assays (intact PTH 150 pg/mL ; normal 9~55). The serum level of a PTHrP was also increased as measured in C-terminal region specific radioimmunoassay (PTHrP 99.1 pmol/L; normal 13.8~55.3). There are no evidences of coincidental primary hyperparathyroidism in parathyroid MIBI scan and other imaging studies including neck ultrasonography and computed tomography. These results suggest that simultaneous elevation of serum PTH and PTHrP in this patient can be caused by production of both PTHrP and PTH in other nonparathyroid lesions such as squamous cell carcinoma.

  • The parathyroid hormone plays a major role in the metabolism of calcium and phosphorus. In hypoparathyroidism the parathyroid glands are atrophied or absent associated with autoantibodies against parathyroid tissue. Pseudohypoparathyroidism is a metabolic disease caused by the disturbance in peripheral action of parathormone, but parathormone level is normal. In general, patients with pseudohypoparathyroidism have short stature, round face, brachydactylia, obesity, mental retardation, cataracts & ectopic calcifications on soft tissues. Dental manifestations are enamel hypoplasia, delayed eruption, blunting of root apex, hypodontia, pulp calcification, thickened lamina dura, excessive caries & malocclusion. In this case, intraoral examination showed enamel hypoplasia on the erupted permanent teeth & hypermobility on the remaining deciduous teeth. From the radiographic view severe dental anomalies were observed on canines and shortening and blunting of root apex was observed on mandibular incisors. Pathologic root resorption was also observed on deciduous teeth.

  • Ectopic cervical thymic tumor, first described in 1941 by Boman, is a rare tumor of the neck displaying the same histologic features as mediastinal thymoma. It was classified into benign thymoma, invasive (or malignant) thymoma, thymic carcinoma histopathologically and clinically. The ectopic cervical thymic tumor is misdianosed as the thyroidal mass on radiologic examination and FNA cytology due to its rarity and unusual location. Recently, we have experienced two cases of ectopic cervical thymic tumor misdiagnosed as thyroid mass ; a case of thymic carcinoma;the other of invasive thymoma. So, we report these cases with review of the literature.

  • Ectopic thyroid gland is a defined as thyroid tissue located in a site other than its usual pre-tracheal location. Ultrasound examination, CT scan, thyroid scan, and thyroid iodine uptake test are all valuable modalities for a differential diagnosis. Although most of cases are asymptomatic, treatment is indicated when there are symptoms related to progressive growth of mass. This article reports a ectopic thyroid cyst in the anterior neck that was similar to deep neck infection accompanied by acute airway obstruction.
