Spectrum of mitochondrial genomic variation in parathyroid neoplasms
Endocrine, 2021Mitochondrial DNA (mtDNA) variations have been implicated in various cancer types. Several attempts have been made in benign parathyroid adenoma (PA); however, mtDNA variants and copy number alterations have not been investigated in parathyroid carcinoma (PC).

Differentiating Atypical Parathyroid Neoplasm from Parathyroid Cancer
Annals of Surgical Oncology, 2016The differentiation of benign parathyroid gland atypia and true parathyroid carcinoma (PC) can be challenging. In some instances, patients are classified as having 'atypical parathyroid neoplasms' (APNs), explicitly acknowledging that the distinction between benign and malignant disease appears impossible to determine.

Parathyroid Neuroendocrine Neoplasms
2020The parathyroid glands are the site of common benign neuroendocrine tumors, including adenomas and lipoadenomas. Metastatic disease is very rare, and local growth does not usually have significant sequelae; even large non-metastatic tumors are easily resected.

Novel PRUNE2 Germline Mutations in Aggressive and Benign Parathyroid Neoplasms [PDF]
Cancers, 2023 Parathyroid tumors are mostly sporadic but can also occur in familial forms, including different kinds of genetic syndromes with varying phenotypes and penetrance.

Thyroid and Parathyroid Neoplasms
2020The thyroid and adjacent parathyroid glands demonstrate a variety of benign and malignant pathology, with nodular thyroid disease being the most common pathology encountered in most routine head and neck imaging practice. A variety of thyroid cancers exist, and imaging strategy for staging, surveillance and follow-up depend upon the cancer type.

The Unequal Distribution of Parathyroid Neoplasms in Male Patients
The American Surgeon™, 2013There is a known lesser incidence of primary hyperparathyroidism and parathyroid neoplasms in male patients. Any difference in the anatomic distribution between males and females has not been documented. Review of our institutional experience with 125 pathologically confirmed parathyroid adenomas (119) or carcinomas (six) from 2000 through 2012 was ...

Thyroid and Parathyroid Neoplasms
2006X-rays of the neck, the chest or barium swallows can give hints mainly regarding thyroid disease, such as narrowing of tracheal, hypopharyngeal or oesophageal lumen, their shifting away from the midline, and coarse calcifications (Fig. 14.1). Their importance has remarkably decreased since the development and refinement of modern cross-sectional ...

Thyroid and Parathyroid Neoplasms
2011This chapter offers an overview of the epidemiology and aetiology, clinical and histological characteristics and classification, and staging of thyroid and parathyroid neoplasms before providing a more focused and illustrated description of the imaging findings. The indications and the role of ultrasound, ultrasound-guided fine needle aspiration, cross-

Analysis of Parathyroid Neoplasms by Interphase Fluorescence In Situ Hybridization
The American Journal of Surgical Pathology, 2004Recent studies have indicated that numerical chromosomal abnormalities, including changes in cyclin D1 and p53, may be involved in parathyroid tumorigenesis. We analyzed a series of parathyroid neoplasms with DNA fluorescent probes to evaluate the diagnostic and prognostic utility of numerical abnormalities of chromosomes 1, 6, 9, 11, 13, 15, 17, and ...

Epithelial-mesenchymal transition in parathyroid neoplasms
2009Epithelial-mesenchymal transitions (EMT) are essential for normal embryonic development and for progression of non-invasive tumor cells into metastatic carcinomas. During embryogenesis, the parathyroid glands develop from pharyngeal pouches and migrate to their final destinations, densely enclosed by mesenchymal neural crest cells.
