Somatostatin receptor expression in parathyroid neoplasms [PDF]

Endocrine Connections, 2019
Introduction: Parathyroid carcinoma represents a rare cause of primary hyperparathyroidism. Distinguishing carcinoma from the benign tumors underlying primary hyperparathyroidism remains challenging.

Clinical and molecular genetics of parathyroid neoplasms [PDF]

Best Practice and Research in Clinical Endocrinology and Metabolism, 2010
Primary hyperparathyroidism (HPT) results from the excessive secretion of parathyroid hormone from parathyroid tumours. While most HPT is sporadic, it is associated with a familial syndrome in a minority of cases. The study of these syndromes has helped define the pathophysiology of both familial and sporadic parathyroid neoplasms.

Parathyroid Retrospective Analysis of Neoplasms Incidence (pTRANI Study): An Italian Multicenter Study on Parathyroid Carcinoma and Atypical Parathyroid Tumour [PDF]

Journal of Clinical Medicine, 2023
Background: Parathyroid cancer (PC) is a rare sporadic or hereditary malignancy whose histologic features were redefined with the 2022 WHO classification. A total of 24 Italian institutions designed this multicenter study to specify PC incidence, describe its clinical, functional, and imaging characteristics and improve its differentiation from the ...

Genetic and Epigenetic Alterations in Parathyroid Neoplasms. [PDF]

Iran J Pathol, 2022
The exact etiology of parathyroid carcinomas (PC) is still unknown. Their associations have with several inherited syndromes or specific genetic lesions have been established. The management of PC is challenging for clinicians. The complexity of molecular phenotypes increases with tumor aggressiveness.

Primary exploration of cell-free DNA in the plasma of patients with parathyroid neoplasms using next-generation sequencing [PDF]

Cancer Cell International
Background and aims Plasma cell-free DNA (cfDNA) has been used to monitor gene mutations and diagnose tumors. Discriminating parathyroid carcinoma (PC) from parathyroid adenoma (PA) before surgery is difficult because of the overlap in clinical features ...

Intrahepatic ectopic atypical parathyroid tumor causing primary hyperparathyroidism: a case report [PDF]

Frontiers in Medicine
Primary hyperparathyroidism (PHPT) most commonly arises from cervical parathyroid pathology, with ectopic disease representing a rare entity. We report a case of PHPT diagnosed during fracture workup in a female patient who manifested persistent ...

IMMUNOCHEMICAL IDENTIFICATION OF PARATHYROID HORMONE IN NON-PARATHYROID NEOPLASMS ASSOCIATED WITH HYPERCALCEMIA [PDF]

Journal of Experimental Medicine, 1964
1. Immunochemical cross-reactivity, but not identity, has been demonstrated between bovine parathyroid hormone and an antigen in biologically active extracts of human parathyroid tissue by quantitative C' fixation and C' fixation inhibition. 2.

Parathyroid Neoplasms: The Army Hospital (Research & Referral) Experience [PDF]

Medical Journal Armed Forces India, 2006
Neoplasms of the parathyroid are common but parathyroid carcinoma is exceptionally rare. In contrast to most other malignant endocrine tumours that are usually less hormonally active, malignant parathyroid tumours are hyper functional. Malignant parathyroid tumours pose a diagnostic dilemma for the pathologist.To study the clinicopathological profile ...
