Between January 2012 to 2016, 20 patients with primary hyperparathyroidism underwent surgical exploration for presumed diagnosis of parathyroid adenoma. Nineteen patients underwent ultrasonography of neck and USG was found to be accurate in localizing the adenoma in 84.2%. Seventeen patients underwent sestamibi isotope scanning and imaging correlated with operative findings in 94.1%. Combined accuracy of ulrasound and sestamibi scan which was done in 17 patients was 95%. Seventeen patients underwent unilateral exploration and there was resolution of disease in 94...

OBJECTIVES: Preoperative localization of parathyroid adenomas in patients with primary hyperparathyroidism facilitates targeted surgery. We assessed the sensitivity of 3-dimensional (3D) sonography for preoperative localization of abnormal parathyroid glands. METHODS: We conducted a retrospective review of patients who underwent parathyroidectomy for primary hyperparathyroidism at a single site at our institution. We compared preoperative 2-dimensional (2D) sonography, 3D sonography, and sestamibi scans with final gland localization at surgery...

Brown tumors seen in hyperparathyroidism are rare, non-neoplastic lesions because of abnormal bone metabolism, and they can mimic benign bone tumors or malignancy. Although biopsy is considered as the gold standard for diagnosis, it can be inconclusive. As the diagnosis of brown tumors is often challenging, a high index of suspicion is essential for diagnosis. We present a case of 21-year-old woman who presented with multiple painful bony lesions, which were initially misdiagnosed as fibrous dysplasia. Due to persistent bone pain and deterioration in her physical mobility, she was referred to tertiary care centre...

AIM: The main goal of our study was to confirm the usefulness of intra-operative parathyroid hormone (PTH) monitoring (ioPTH) when using minimally invasive techniques for treatment of sporadic Primary hyperparathyroidism (pHTP). Furthermore, we aimed to evaluate if ioPTH monitoring may help to predict the etiology of primary hyperparathyroidism, especially in malignant or multiglandular parathyroid disease. METHODS: A retrospective review of 125 consecutive patients with pHPT who underwent parathyroidectomy between 2001 and 2016 at the Department of General Surgery was performed...

Parathyroid tumors are common endocrine neoplasias associated with primary hyperparathyroidism, a metabolic disorder characterized by parathormone hypersecretion. Parathyroid neoplasia are frequently benign adenomas or multiple glands hyperplasia, while malignancies are rare. The epigenetic scenario in parathyroid tumors has just begun to be decoded: DNA methylation, histones and chromatin modifiers expression have been investigated so far. The main findings suggest that DNA methylation and chromatin remodeling are active and deregulated in parathyroid tumors, cooperating with genetic alterations to drive the tumor phenotype: the tumor suppressors menin and parafibromin, involved in parathyroid tumorigenesis, interact with chromatin modifiers, defining distinct epigenetic derangements...

The 85% of cases of primary hyperparathyroidism (PHPT) are due to parathyroid adenomas (PA) and less than 1% to parathyroid carcinomas (PC). The PA usually measure <2 cm, weigh <1 g and generate a mild PHPT, whereas the PC usually exceeds these dimensions and are associated with a severe PHPT. However, giant PA (GPA), which is defined as those larger than 3 g, has been documented. Those may be associated with very high levels of PTH and calcium. In these cases, their differentiation before and after surgery with PC is very difficult...

We present a case of an ectopic mediastinal parathyroid adenoma in a 58-year-old male patient. We show how different imaging modalities were successfully used to reach a diagnosis. We particularly focus on the role of four-dimensional CT scan in preoperative localization of ectopic adenomas and discuss how diverse imaging modalities can be integrated in the workup of ectopic parathyroid adenomas.

BACKGROUND: Long-term severe hyperparathyroidism leads to thinning of cortical bone and cystic bone defects referred to as osteitis fibrosa cystica. Cysts filled with hemosiderin deposits may appear colored as "brown tumors." Osteitis fibrosa cystica and brown tumors are occasionally visualized as multiple, potentially corticalis-disrupting bone lesions mimicking metastases by bone scintigraphy or (18)F-fluorodeoxyglucose positron emission tomography. CASE PRESENTATION: We report a case of a 72-year-old white woman who presented with malaise, weight loss, and hypercalcemia...

We discuss a case of an 81-year-old man who presented to hospital with a case of severe hypercalcaemia (5.07 mmol/L). The two most common causes of hypercalcaemia, making up around 90% of the cases, are malignancy and primary hyperparathyroidism. Initial investigations are guided by this knowledge. In this case, no underlying malignancy or evidence of a parathyroid adenoma causing primary hyperparathyroidism was found. Instead, on further history, it was found that this patient had troublesome dyspepsia symptoms for which he had ingested 10-12 calcium carbonate tablets a day for the preceding 2 years...

Multiple Endocrine Neoplasia type 1 (MEN1) syndrome is a rare complex tumor-predisposing hereditary disorder, inherited in an autosomal dominant manner (OMIM 131100). MEN1 is characterized by tumors of the parathyroids, the neuroendocrine cells of the gastro-entero-pancreatic tract, and the anterior pituitary. The molecular mechanisms that control parathyroid tumorigenesis are still poorly understood. Here we studied the global microRNAs (miRNAs) expression profile in MEN1 parathyroid adenomas to understand the role of these regulatory factors in MEN1 parathyroid tumorigenesis...

BACKGROUND: Endocrine surgeon localizes solitary adenoma (SA) in preoperative time by cervical ultrasound (c-US) and/or 99mTC Sesta MIBI scintigraphy (MIBI-S), but in clinical practice they often show discordant results. The aim of our study is to verify if c-US and MIBI-S have different sensitivity in preoperative localization of SA, depending on its localization, in planning minimally-invasive video-assisted parathyroidectomy (MIVAP). METHODS: This is a retrospective analysis of data (demographics data, preoperative localization of SA by US and MIBI-S, presence of associated thyroid disease, preoperative calcemia, preoperative serum PTH, surgical time, intraoperative PTH values, day 1 postoperative calcemia, definitive histological report) about patients consecutively submitted to MIVAP because of SA between January 2011 and January 2014 in the department of endocrine and general surgery of the University Hospital of Parma (Italy)...

INTRODUCTION Parathyroidectomy is the definitive treatment for primary hyperparathyroidism but the intraoperative identification of adenomas is challenging. The aim of this study was to evaluate the utility of a radionuclide probe (RNP) in addition to intraoperative parathyroid hormone ( IOPTH) measurement as an intraoperative diagnostic adjunct in patients undergoing parathyroidectomy for primary hyperparathyroidism. METHODS This was a retrospective cohort study of patients treated between 2004 and 2015 in a university affiliated teaching hospital...

SUMMARY: A 54-year-old man had gastrinoma, parathyroid hyperplasia and pituitary tumor. His family history indicated that he might have multiple endocrine neoplasia type 1 (MEN1). MEN1 gene analysis revealed a heterozygous germline mutation (Gly156Arg). Therefore, we diagnosed him with MEN1. Endocrinological tests revealed that his serum prolactin (PRL) and plasma adrenocorticotropic hormone (ACTH) levels were elevated to 1699 ng/mL and 125 pg/mL respectively. Immunohistochemical analysis of the resected pancreatic tumors revealed that the tumors did not express ACTH...

We report here a rare case of primary hyperparathyroidism that was associated with an ectopic parathyroid adenoma located in the mediastinum. A 66-year-old woman suffering from primary hyperparathyroidism had been followed-up on an outpatient basis for over 10 years. She suffered from persistent urolithiasis and osteopenia due to hypercalcemia. After technetium-99-sestamibi (99mTc-MIBI) scintigraphy revealed an ectopic adenoma in the superior mediastinum, thoracoscopic resection of the tumor was performed. Subsequently, her serum parathyroid hormone (PTH) level decreased dramatically and her serum calcium concentration was restored to normal...

A young 18-year-old female patient with general bone pain and history of multiple fractures brought her to our medical attention. Laboratory work showed hypercalcemia and high parathyroid hormone levels in the blood. Radiograph imaging revealed severe scoliosis with multiple vertebrae fractures with decreased bone mineral density. Sestamibi showed parathyroid adenoma. This case emphasizes the importance of maintaining a primary hyperparathyroidism as a differential diagnosis when a young patient presents with a multiple pathologic fractures history...

OBJECTIVE: Primary hyperparathyroidism (pHPT) is often accompanied by underlying thyroid pathology and 1 to 36% of these thyroid pathologies are malignant. How the identification of these lesions affects patient management is unclear. We present a single-center experience with the prevalence of concomitant thyroid cancer in patients who underwent parathyroidectomy for pHPT. MATERIALS AND METHODS: This was a retrospective cohort study. Two hundred-two patients with primary hyperparathyroidism included study...
