Purpose: Most cases of primary hyperparathyroidism are due to parathyroid adenoma or parathyroid hyperplasia. Parathyroid carcinoma is a very rare cause of hyperparathyroidism. Although the diagnosis of parathyroid carcinoma is usually established by pathologic criteria especially of vascular or capsular invasion, some clinical and biochemical features differentiate it from benign forms of hyperparathyroidism. We under-took a retrospective study in 6 patients with parathyroid carcinoma, with the aim of conveying experience from management for this rare cause of hyperparathyroidism. Methods: Clinical symptoms, biochemical laboratory, radiologic, and intraoperative findings, local recurrence and distant metastasis were analyzed in 6 patients diagnosed pathologically as a parathyroid carcinoma after operation from 1992 to 2001. Results: Mean age was 50.2 years (33.0-60.0 years) and male to female ratio was 1:1. Neck mass was found in 5 patients, multiple bone pain in 3 patients and renal stone in 1 patient. One case has suffered from chronic renal failure for 19 years. Although preoperative laboratory evaluations showed the aspects of hyperparathyroidism in all cases, mean serum calcium level was 11.2mg/dl(10.5-12.1mg/dl), slightly elevated. Laboratory values after surgery were within the normal range in 5 cases. However, in one case with chronic renal failure, serum PTH levels, serially checked, were above the normal range. Any of imaging methods failed to suggest a parathyroid carcinoma preoperatively. Parathyroid adenoma was suspected in 3 cases, thyroid cancer in the other cases before surgery. The extent of resection was radical resection of parathyroid lesion with more than unilateral thyroid lobectomy and central compartment neck node dissection and in 2 cases, the resection of recurrent laryngeal nerve or strap muscles was added. During follow-up period, any local or systemic recurrence were not evident in all the cases. Conclusion: Although parathyroid carcinoma is a rare disease and its preoperative diagnosis, in our experience, could not easily be made, the understanding of characteristic clinical and biochemical feature could help diagnosis at first surgery. Radical resection without remaining residual tumor is most important for the management of the parathyroid cancer.

부갑상선 호르몬이 과도하게 분비되는 경우 전반적인 골의 탈석회화에 의해 골막성 골흡수 및 골의 동통 등의 증상이 발현될 수 있다. 본고에서 소개된 환자의 경우 광범위한 치근 흡수를 동반한 부정 교합 환자로, 임상 및 두부 방사선 계측사진 분석에서 상악 열성장과 하악 과성장이 동반된 골격성 III급 부정 교합으로 진단되 었으며, 병리검사결과 부갑상선 호르몬 및 성장 호르몬의 수치가 증가된 것으로 보아 부갑상선 기능항진증으로 판단되었다. 방사선 사진 분석 결과 광범위한 치근의 흡수를 관찰할 수 있었으며 골다공증과 유사하게 골소주 형태가 매우 성기면서 ground glass 양상을 보였다. 이와 같이 부갑상선 기능항진증에 의해 골질뿐만 아니라 치근이 영향을 받은 것은 매우 드문 경우로 생각된다. 또한 부갑상선 기능항진증에 의해 내장두개의 골침착이 감소될 수 있다는 동물실험 결과를 볼 때 III급 부정교합의 원인이 상악 열성장인 점과 연관하여 매우 흥미로운 점으로 지적된다. 따라서 부갑상선 기능항진증의 다양한 증상 및 양태에 대한 조기진단 및 이에 대한 지식은 교정진단 및 치료에 중요한 역할을 할 수 있다고 생각된다.

임상적으로 부갑상선 항진증이 의심되는 8명의 환자들을 대상으로 하여 수술 전에 정확한 병변의 위치를 확인하고자 $^{201}T1/^{99m}Tc$ 감영 스캔을 시행하였다. 6예에서 부갑상선 선종이 진단되었고 이들 전부가 수술 소견과 동일한 위치에서 양성소견을 보였으며, 수술 후 병리조직학적으로 확진 되었다. 나머지 2예는 만성 신부전, MEN type I 과 동반된 미만성 부갑상선 과형성증이었다. 결론적으로 $^{201}T1/^{99m}Tc$ 감영 스캔은 부갑상선 항진증의 진단에 유리하며, 특히 수술 전, 부갑상선 선종의 위치 확인에 유용하다.

Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.

A 3-year-old male Maltese dog(weighing 2.5 kg) was referred with an excessive movement of mandible and depression. Comprehensive diagnostic investigation revealed an end-stage of renal disease with secondary hyperparathyroidism. The renal allograft was performed after the condition of dog was stabilized by hemodialysis and medical treatment. After transplantation, the renal function of this dog was returned to normal. thereafter, the dog died suddenly without apparent clinical signs. The subsequent pathological studies revealed the actual etiology of death was not clearly identified However acute pancreatitis caused by abrupt introduction of food after prolonged luting might be involved in the etiology. This case study showed the necessity of pancreatic function test in postoperative management after renal transplantation.

Background: Secondary hyperparathyroidism (SHPT) is common in patients with chronic kidney disease, affecting most of those who are receiving dialysis. Cinacalcet, a novel calcimimetic, targets the calcium-sensing receptor to lower PTH levels in dialysis patients. Objective: This study aimed to assess efficacy, safety and appropriateness of use of cinacalcet in dialysis patients. Method: This retrospective study was performed on total 24 cases with identified intact parathyroid hormone (iPTH), serum calcium and phosphorus levels before and 4 weeks after cinacalcet initiation at a teaching hospital from July 1st, 2011 to October 31st, 2012. Results: Cinacalcet decreased iPTH by 19% from baseline after 4weeks treatment and it was statistically significant (p<0.001). Cinacalcet also significantly decreased iPTH levels regardless of dialysis modality (hemodialysis group versus peritoneal dialysis group) and severity of SHPT (iPTH 300-800 pg/ml group versus iPTH >800 pg/ml group). Serum calcium, phosphorus and Ca x P levels were decreased without statistical significance. Gastrointestinal events, headache and hypocalcemia were the most common side effects. Monitoring for iPTH and serum calcium was not performed appropriately. 43.7% patients initiated cinacalcet therapy at serum calcium level< 9.0 mg/dl. Conclusion: In conclusion, cinacalcet lowers parathyroid hormone levels with no serious side effects. However, it is required to avoid cinacalcet treatment in patients with low serum calcium levels and monitor iPTH and serum calcium levels during cinacalcet administration.

Parathyroid carcinoma is rare, occurring in less than 2-3% of the patients with primary hyperparathyroidism. In the patients with chronic renal failure, the incidence is extremely low. Only 13 cases of parathyroid carcinoma with chronic renal failure have been described in the world literature. We report a case of parathyroid carcinoma in a 43-year-old man who has been suffered from chronic renal failure for 19 years. To our knowledge, this is the first case of parathyroid carcinoma occurring in the thyroid gland associated with secondary hyperparathyroidism.

Primary hyperparathyroidism (PHP) is rare in dogs. Mainly functional solitary parathyroid adenoma causes hypercalcemia due to excessive autonomous secretion of parathyroid hormone (PTH). PHP can be diagnosed based on serum calcium phosphorus, ionized calcium and PTH, and cervical ultrasound provides important information about the number size and location of parathyroidal lesion. Ultrasound guided intralesional ethanol injection has been used as an alternative to surgical treatment of PHP. In this case, PHP was diagnosed in 12 year-old Pug with clinicopathologic examination and cervical ultrasound, and the parathyroidal mass was ablated successfully through ultrasound guided ethanol injection.

목적 : 원발성 부갑상선기능 항진증의 대부분의 원인인 부갑상선 선종의 유일한 완치는 수술이며 수술의 성패에 가장 중요한 것은 수술전의 정확한 ??소의 확인이다. 다양한 영상검사들이 동원되고있으나 각가 결점이 있고 가장 특이도가 높은 $^{201}T1-^{99m}Tc$감영 촬영방법도 검사방법등에 문제점이 있다. 이에 원발성 부갑상선기능 항진증 환자에게 최근에 사용되고있는 $^{99m}Tc$-Sestamibi 부갑상선 스캔의 유용성을 알아보고자 하였다. 대상 및 방법 : 19명의 부갑상선기능 항진증환자에서 모든 환자에게 초음파 검사, CT, $^{201}T1-^{99m}Tc$감영 촬영을 시행하고 그중 5명은 $^{99m}Tc$-Sestamibi 부갑상선 스캔을 시행하여 수술후 확진결과와 함께 비교하였다. 결과 : 초음파 검사와 CT 및 $^{201}T1-^{99m}Tc$감영 스캔은 19예중 각가 12예(67.1%), 14예(78.9%) 그리고 17예(89.5%)에서 병소확인이 가능하였고 $^{99m}Tc$-Sestamibi 부갑상선 스캔은 시행한 5예(100%) 모두에서 병소 확인이 가능하였다. 결론 : 이상의 결과로 $^{99m}Tc$-Sestamibi 부갑상선 스캔은 원발성 부갑상선기능 항진증의 수술전 병소확인에서 유용한 검사법으로 이용될 수 있으리라 사료된다.
