Background: The use of intraoperative neuromonitoring (IONM) provides surgeons with real time information about recurrent laryngeal nerves (RLN) functional integrity. Hence, allowing them to modify the initially scheduled bilateral procedure, to a two-stage thyroidectomy in cases of loss of signal (LOS) on the first side of resection resulting in minimization of bilateral RLN injury. The purpose of our study was to present our results since the implementation of the above mentioned process in both malignant and benign thyroid disease...

BACKGROUND: Increasing evidence has indicated parathyroid hormone type 1 receptor (PTHR1) plays important roles for the development and progression of osteosarcoma (OS). However, its function mechanisms remain unclear. The goal of this study was to further illuminate the roles of PTHR1 in OS using microarray data. METHODS: Microarray data were available from the Gene Expression Omnibus database under the accession number GSE46861, including six tumors from mice with PTHR1 knockdown (PTHR1...

Parathyroid carcinoma is an extremely rare endocrine malignancy that accounts for less than 1% of cases of primary hyperparathyroidism. We report a 44-year-old woman who presented with fatigue and diffuse bone pain. Laboratory findings revealed highly elevated serum calcium and parathyroid hormone (PTH) levels and a 4.5 × 3 × 2.5 cm cystic lesion in the lower pole of the right thyroid lobe that was shown histologically to be a parathyroid carcinoma. Ten years later, the patient developed brain and pulmonary metastases and recurrence of PTH-related hypercalcemia...

BACKGROUND: Hereditary primary hyperparathyroidism may be syndromic or nonsyndromic (familial isolated hyperparathyroidism). Recently, germline activating mutations in the GCM2 gene were identified in a subset of familial isolated hyperparathyroidism. This study examined the clinical and biochemical characteristics and the treatment outcomes of GCM2 mutation-positive familial isolated hyperparathyroidism as compared to sporadic primary hyperparathyroidism. METHODS: We performed a retrospective analysis of clinical features, parathyroid pathology, and operative outcomes in 18 patients with GCM2 germline mutations and 457 patients with sporadic primary hyperparathyroidism...

BACKGROUND: The occurrence of parathyroid carcinoma in Multiple Endocrine Neoplasia type I (MENI) is rare and the 15 cases of malignant parathyroid tumour reported so far have been associated with MENI in individuals and not with multiple members within a family. METHODS: We report on a 61-year-old man, operated for a 7.3 cm parathyroid carcinoma infiltrating the esophagus. In his brother a 4.6 cm parathyroid carcinoma was diagnosed histologically, while in the daughter, neck ultrasonography revealed 2 extrathyroidal nodules, yet to be excised...

RATIONALE: Parathyroid carcinoma is a rare endocrine malignancy. Acute pancreatitis as an initial manifestation of parathyroid carcinoma has been rarely reported. PATIENT CONCERNS: A 22-year-old woman was admitted to emergency room with a sudden attack of severe epigastric pain. DIAGNOSES: Acute pancreatitis was diagnosed as elevated levels of serum amylase. During the work-up for acute pancreatitis, patient's abnormally increased serum calcium and bones destruction revealed by abdominal computed tomography (CT) scan raised the suspicion of hyperparathyroidism or malignancy...

The aim of the study was to investigate whether carbon nanoparticles (CNs) can improve the dissection of lymph nodes and protect parathyroid glands (PGs) during reoperation for patients with papillary thyroid carcinoma (PTC).PTC patients who previously underwent thyroidectomy and later received reoperation between January 2009 and January 2016 were retrospectively recruited. We compared the patients who had CN suspension injected into the residual thyroid gland with a control group of patients who did not have the injection...

Parathyroid carcinoma is an uncommon malignancy and the probability of an intrathyroidal location is low. Fine needle aspirations (FNA) of these presumably "thyroid nodules" can lead to misinterpretation because of the similarities in cytological features of parathyroid and thyroid lesions. Despite limitations, USG guided FNA cytology remains the first line of investigation. We report a case of intrathyroidal parathyroid carcinoma presenting with hypercalcemia and elevated serum parathormone. Cytological findings attributed it to a possible parathyroid lesion and histopathology revealed a parathyroid carcinoma...

Multiple endocrine neoplasia type 2 (MEN2) refers to the autosomal dominant neuroendocrine tumour syndromes, MEN type 2A (MEN2A) and MEN type 2B (MEN2B). They are typified by the development of medullary thyroid carcinoma (MTC), phaeochromocytoma and parathyroid hyperplasia in MEN2A, and MTC, phaeochromocytomas, ganglioneuromatosis and skeletal abnormalities in MEN2B. The aggressiveness of MTC is variable according to genotype, and although it is still the major cause of mortality in both conditions, prognosis has improved dramatically in those diagnosed and treated at a young age thanks to predictive genetic testing...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving chronic dialysis therapy. Although cinacalcet can control parathyroid function and bone turnover, preventing ectopic calcification remains challenging. Cinacalcet can also suppress PTH secretion due to parathyroid carcinoma in the same way as it does for parathyroid hyperplasia in the uremic condition. We present a case of parathyroid carcinoma partially controlled by cinacalcet, in which tumorous calcinosis was successfully resolved by total parathyroidectomy...

We reviewed the surgical management of primary hyperparathyroidism through a retrospective chart review of 200 parathyroidectomy procedures performed over a 12 year period. Epidemiological data and accuracy of radiological investigations used in identifying pathological parathyroid tissue location were assessed. We determined how often simultaneous removal of thyroid tissue was required during parathyroidectomy and the associated pathology. Radiology reports were screened to determine if confirmed thyroid pathology from histological specimens were referenced pre-operatively...

Parathyroid carcinomas are rare endocrine tumors which comprise 0.3-5.6% of all causes of hyperparathyroidism. 90% of them are hormonally active, while 10% of them may be non-functional. They mostly occur in a single parathyroid gland. Concurrent involvement of both parathyroid glands is quite rare. A 57-year-old male patient was admitted to emergency department with the complaint of dyspnea. Thorax tomography revealed a retrosternal mass. The mass was thoracoscopically excised by thoracic surgeons. Histopathological examination result of the mass was reported as parathyroid carcinoma...

Super scan is a well-known finding described in skeletal scintigraphy characterized by uniform symmetrically increased radiopharmaceutical uptake by bones and consequently diminished renal parenchymal activity. Sy et al. hypothesized that the faint visualization of renal cortex in bone scintigraphy might be the result of increased uptake of radiopharmaceutical by pathologic bones and reduced phosphate excretion. The super scan on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has been observed in various conditions such as prostate cancer, lung cancer, renal adenocarcinoma, gastric cancer and primitive neuroectodermal tumor of the kidney...

The risk factors of hypoparathyroidism after total thyroidectomy (TT) with central lymph node dissection (CND) have not been completely defined. The aim of the study was to evaluate the risk factors of hypoparathyroidism after the surgery.We retrospectively reviewed our patients who underwent TT and CND (including lateral lymph node dissection) for thyroid carcinoma between January 2013 and June 2016. According to the postoperative serum levels of parathyroid hormone within 6 months, the patients were divided into normal, transient hypoparathyroidism, and permanent hypoparathyroidism groups...

Parathyroid carcinoma (PC) is a rare neoplasia difficult to diagnose preoperatively. It mainly occurs as a sporadic disease but also as part of familial PHPT. At variance with patients with the benign counterpart, the phenotype of these patients is characterized by a severe primary hyperparathyroidism (PHPT). The clinical features are mostly due to the effects of the excessive secretion of PTH by the functioning tumor and hypercalcemia rather than to the tumor burden. The prognosis is poor and unmanageable hypercalcemia accounts for death in the majority of cases...

Even with a favorable prognosis, the health-related quality of life (HRQoL) of papillary thyroid carcinoma (PTC) patients remains unclear and conflicting. Thus, in the present study, we compared the HRQoL of PTC patients with that of the general population (GP).The study was performed in our thyroid and parathyroid surgery department, and 186 PTC patients who had undergone thyroidectomy were included. The exclusion criteria were an age < 18 years, no follow-up, and the presence of other malignant neoplasms...
