The intrathyroidal parathyroid adenomas (IPA) represent a rare cause of primary hyperparathyroidism whose location difficults appropriate surgical removal. We present the case of a patient diagnosed of parathyroid adenoma by presurgical scintigraphy in which finally during the parathyroidectomy, the lesion location was intrathyroidal. We consider that the intrasurgical parathyroid scintigraphy ...
OBJECTIVES Parathyroid carcinoma (PC) is a rare parathyroid tumor compared to parathyroid adenoma (PA) and atypical parathyroid adenoma (APA). Recent studies have suggested parafibromin has a role in the differential diagnosis of parathyroid tumors. We sought to determine the role of parafibromin as well as galectin-3, Ki-67, and HBME-1 as diagnostic markers in the differential diagnosis of par...
Primary hyperparathyroidism is a generalized disorder of bone and mineral metabolism caused by autonomous secretion of parathyroid hormone. It is primarily seen in adults with typical age of presentation between third and fifth decades of life. Juvenile hyperparathyroidism is a rare disorder. The common presentations in order of incidence are fatigue and lethargy, headache, nephrolithiasis, nau...
Ultrasonically guided fine needle aspiration of suspect parathyroid tissue to determine parathyroid hormone concentration Since the study of Arima et al,1 several reports have confirmed that enlarged parathyroid glands can be located preoperatively using ultrasound. A general problem has been the difficulty of distinguishing nodular thyroid lesions from enlarged parathyroid glands.2 3 We report...
BACKGROUND To explore underlying molecular mechanisms in the pathogenesis of symptomatic sporadic primary hyperparathyroidism (PHPT). MATERIALS AND METHODS Forty-one parathyroid adenomas from patients with symptomatic PHPT and ten normal parathyroid glands either from patients with PHPT (n=3) or from euthyroid patients without PHPT during thyroid surgery (n=7) were analyzed for vitamin D rece...
