The Hyperparathyroidism with Jaw-Tumours syndrome is caused by mutations of the CDC73 gene: it has been suggested that early onset of the disease and high Ca2+ levels may predict the presence of a CDC73 mutation. We searched for large deletions at the CDC73 locus in patients with: HPT-JT (nr 2), atypical adenoma (nr 7) or sporadic parathyroid carcinoma (nr 11) with a specific MLPA and qRT-PCR assays applied on DNA extracted from whole blood. A Medline search in database for all the papers reporting a CDC73 gene mutation, clinical/histological diagnosis, age at onset, Ca2+ , PTH levels for familial/sporadic cases was conducted with the aim to possibly identify biochemical/clinical markers predictive, in first diagnosis, of the presence of a CDC73 gene mutation...

OBJECTIVES: Postoperative hypoparathyroidism (HPT) is one of the most common complications in total thyroidectomy for thyroid carcinoma. Parathyroid glands (PTGs) are at risk of being damaged during total thyroidectomy and central neck dissection mainly due to inadvertent removal, interruption of the blood supply or hematoma formation. The purpose of this study was to evaluate the efficacy of our surgical procedure to preserve for parathyroid function retrospectively and to clarify the risk factors of HPT after total thyroidectomy for thyroid cancer...

The application of immunohistochemistry to the diagnosis of thyroid lesions has increased as new biomarkers have emerged. In this review, we discuss the biomarkers that are critical for accurate diagnosis, prognosis, and management. Immunohistochemical markers are used to confirm that an unusual tumor in the thyroid is indeed of thyroid origin, either of follicular epithelial or C-cell differentiation; the various mimics include nonthyroidal lesions such as parathyroid tumors, paragangliomas, thymic neoplasms, and metastatic malignancies...

A 50-year-old female patient with no significant medical history presented with left knee pain. Radiographs of the knee showed a circumferential swelling of the distal femur suggestive of neoplasia. Further evaluation revealed multiple lesions in the left iliac bone and proximal femur. Biopsy was suggestive of a reparative granuloma or an aneurysmal bone cyst. Laboratory assessment showed hypercalcaemia and elevated parathyroid hormone consistent with severe primary hyperparathyroidism. Osseous survey was significant for salt and pepper appearance of the skull...

Parathyroid tumors deregulate microRNAs belonging to the two clusters on the chromosome 19, the C19MC and miR-371-373 clusters. Here, we report that the embryonic miR-372 is aberrantly expressed in half of parathyroid adenomas, (PAds) in most of atypical adenomas and carcinomas (n=15). Through in situ hybridization we identified that miR-372-positive parathyroid tumor cells were scattered throughout the tumor parenchyma. In PAds-derived cells, ectopic miR-372 inhibited the expression of its targets CDKN1A/p21 and LATS2 at both mRNA and protein levels...

In Western countries, the presentation of primary hyperparathyroidism (PHPT) changed from a symptomatic to an asymptomatic disease after the 1970s, whereas in China, only one study has evaluated the changing clinical characteristics and biochemical profiles of PHPT patients. The aim of this study was to explore changes in the clinical characteristics of PHPT in Chinese patients. Overall, 140 consecutive patients with PHPT were studied between January 1, 2010 and June 30, 2016. The patients were divided into two groups: 32 consecutive patients from January 1, 2010 to March 31, 2013 were included in group 1, and 108 consecutive patients from April 1, 2013 to June 30, 2016 were included in group 2...

Technetium-99m methoxy isobutyl isonitrile (99m Tc-MIBI; sestamibi) single-photon emission computed tomography (SPECT)/computed tomography (CT) performed for preoperative localization of parathyroid adenomas or for other indications can reveal incidentalomas. Interpretation of such findings can be challenging, particularly when thyroid or other endocrine tumors are also present. Preoperative staging of a 59-year-old female patient with medullary thyroid carcinoma (MTC) showing moderate hypermetabolism on 18 F-fluorodeoxyglucose positron emission tomography/CT also detected a slightly hypermetabolic pulmonary nodule (standardized uptake value normalized by body weight max = 2...

Pathologists are usually readily able to diagnose parathyroid tissues and diseases, particularly when they have knowledge of the clinical information, laboratory findings, and radiographic imaging studies. However, the identification of parathyroid tissue or lesions can be difficult in small biopsies, ectopic locations, supranumerary glands, and in some oxyphil/oncocytic lesions. Widely available immunohistochemical studies such as chromogranin-A, synaptophysin, keratin, parathyroid hormone, thyroglobulin, and thyroid transcription factor-1 can help in difficult cases...

Objective: To report a case of severe hypercalcemia secondary to primary hyperparathyroidism in a late-preterm pregnant patient and review medical and surgical treatments as well as obstetric and neonatal outcomes. Background: Diagnosis of parathyroid disease during pregnancy can be difficult due to nonspecific presentation. Management decisions are complex and require multidisciplinary collaboration. Case: A 29-year-old G2P1001 woman at 35 weeks and 3 days' gestation presented with preterm contractions, polyhydramnios, pancreatitis, and severe hypercalcemia...

We report a case of severe hyperparathyroidism complicated by osteitis fibrosa cystica in an 83-year-old man post-myocardial infarction. The lesions were evident on magnetic resonance imaging only. A diagnosis of parathyroid carcinoma was considered due to clinical appearance of the parathyroid intraoperatively and the presence of an invasive T3 lesion mimicking metastatic disease. Differentiating parathyroid carcinoma from the benign causes at presentation can be difficult due to overlapping clinical, biochemical, radiological and histological features...

Background: As histopathological findings of parathyroid carcinoma are not certain, the diagnosis of tumors with degenerative changes may be difficult. In these cases, immunohistochemical markers are beneficial. We aimed to research the acceptability of calcium-sensing receptor (CaSR), Galactin-3, Cyclin D1, and Ki-67 as helpful markers in parathyroid tumors in cases which are difficult to diagnose. Materials and Methods: Those cases who had been diagnosed with atypical parathyroid adenoma and parathyroid carcinoma between 2010 and 2015 were reevaluated...

Angiosarcoma is a rare vascular soft tissue tumor of endothelial origin most commonly seen in the elderly as a primary cutaneous head and neck malignancy. Furthermore, a peritoneal angiosarcoma is an exceedingly rare entity. This is the second case of primary peritoneal angiosarcoma reported in literature that is not associated with prior radiotherapy. Herein, we describe a case of primary peritoneal angiosarcoma metastatic to both the liver and bone in a male patient with metachronous renal cell carcinoma and parathyroid adenoma...

A 10-year-old female Australian Cattle Dog was referred for investigation of a mediastinal mass. During clinical examination, a mandarin- sized mass was detected ventrally of the trachea. According to computed tomographic (CT) findings and cytology of a fine-needle aspirate, thyroid neoplasia was suspected. The assumed tumour affected the left thyroid gland and was staged as stadium II because of enlargement of the ipsilateral cervical and retropharyngeal lymph nodes. The left thyroid, including the parathyroid gland, was removed surgically with a guarded prognosis...

It is abundantly clear that tumor-derived parathyroid hormone-related protein (PTHrP), receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) are central contributors in promoting osteolytic process of breast carcinoma bone metastasis. Forcusing on this molecular basis, the study was undertaken to explore the inhibition effects of total flavonoids from Scutellaria barbata D. Don (TF-SB) on human breast carcinoma bone metastasis. MDA-MB-231 cells and nude mouse models of breast cancer bone metastasis were given TF-SB in different concentrations...

PURPOSE: Parathyroid carcinoma (PCa) is a rare endocrine malignancy with poor prognosis and is often difficult to accurately diagnose both before and after surgery. Dysregulated microRNA (miRNA) levels have been identified in PCa using a limited number of samples. The aim of the present study was to verify a group of miRNA markers in a new series of samples to explore their potential significance in PCa diagnosis. METHODS: A total of 58 tissue samples, including 17 PCa lesions and 41 sporadic parathyroid adenomas (PAds), were obtained from 56 primary hyperparathyroidism (pHPT) patients...

BACKGROUND: Approximately 10% of patients with primary hyperparathyroidism (PHPT) have hereditary disease. Hereditary PHPT may be syndromic (MEN1, 2, and 4 and hyperparathyroidism-jaw tumor syndrome) or non-syndromic (familial isolated PHPT). There are limited data on the probability of testing positive for genetic mutation based on clinical presentation. The aim of this study was to determine potential associations between clinical and biochemical features and mutation in susceptibility genes for PHPT in patients with a family history of PHPT...

Multiple endocrine neoplasia type 2A (MEN2A) is a hereditary syndrome. Here, two different RET proto-oncogen mutation were identified from family members of two MEN2A pedigrees by genetic screening. One RET mutations were found at codons 1893 and 1895 in exon 11 (1893-1895delCGA) from pedigree 1, which is a novel mutation, the other occurs at codon 634 (Cys634Arg) in exon 11 from pedigree 2. However, the clinical characteristics were similar in the patients of the two pedigrees. All the patients were in middle-age at onset...
