Introduction Behind of the thyroid gland, there are four glands named parathyroid which help the regulation of the calcium levels across the human body (1). Parathyroid carcinoma (PC) is the most rare cause of primary hyperparathyroidism which is one of the most common endocrine disease. It typically affects the elderly women and men and its clinical appearance is characterized by mild hypercal...

Human multiple endocrine neoplasia subtype 2A (MEN 2A) is characterized by medullary thyroid carcinoma, pheochromocytoma and parathyroid hyperplasia or adenoma in the same individual. In this report, a case of a female Rottweiler with medullary thyroid carcinoma, bilateral pheochromocytoma and parathyroid adenoma was described. Clinical manifestations of muscle weakness, polydipsia, polyuria, d...

BACKGROUND Primary hyperparathyroidism (HPT) is one of the most common endocrine disorders, defined by hypersecretion of parathormone. Primary HPT can be caused by adenoma, hyperplasia, and carcinoma. A great amount of mechanisms contribute to the pathogenesis of this disease, such as genetic predispositions because of the germline-inactivating mutations in the multiple endocrine neoplasia type...

White nodules were observed in the thyroid in two male C3H mice (at 99 and 122 weeks of age) exposed to fast neutrons at the age of 8 weeks. Histopathologically, in both cases, tumors were developed in the region corresponding to the parathyroid gland, and the tumor cells were arranged in a solid sheet or nest-like structures. Necrosis, cell debris and/or hemorrhage were sometimes seen in the c...

Primary hyperparathyroidism (PHP) affects 0.5%-1% of the adult population and presents with classical signs of renal lithiasis, cholecystolithiasis, gastrointestinal ulcerations, depression, and osteoporosis. Parathyroid adenoma, hyperplasia and rarely carcinoma are the underlying pathology. Synchronous thyroid and parathyroid pathologies are described in multiple endocrine neoplasia. We report...

Patients with unresectable parathyroid carcinoma develop severe hypercalcemia, bone fractures and renal failure, and become unresponsive to conventional treatments. It has been shown that successful induction of anti-parathyroid hormone (PTH) antibodies, using PTH peptide fragments for immunisation, normalized serum levels of calcium as well as improved clinical symptoms. Here, we report our ex...
