Parathyroid cysts are a relatively rare cause of neck swelling, and their anatomo-pathological and clinical features are still under debate. Two types of parathyroid cysts have been recognized: the non-functioning or essential forms, which are more frequent, and the adenomatous or functioning parathyroid cysts, which are rarer and cause hyperparathyroidism. Two cases of parathyroid cysts are re...

BACKGROUND The occurrence of parathyroid carcinoma in multiple endocrine neoplasia type I (MENI) is rare and the 15 cases of malignant parathyroid tumor reported so far have been associated with MENI in individuals and not with multiple members within a family. METHODS We report on a 61-year-old male, operated for a 7.3 cm parathyroid carcinoma infiltrating the esophagus. In his brother, a 4....

BACKGROUND Parathyroid dysfunction leading to symptomatic hypocalcemia is not uncommon following a total or completion thyroidectomy and is often associated with significant patient morbidity and a prolonged hospital stay. A simple, reliable indicator to identify patients at risk would permit earlier pharmacologic prophylaxis to avoid these adverse outcomes. We examined the role of intact parat...

the coexistence of medullary thyroid carcinoma (mtc), papillary thyroid carcinoma (ptc) and parathyroid adenoma is an uncommon clinical entity. here, we report a case of mtc, ptc, and parathyroid adenoma diagnosed incidentally on a routine physical examination of the neck for the work-up of diabetes. the patient had neither symptoms of hypercalcemia nor those related to mtc and ptc.

 Abstract Background: Primary hyperparathyroidism is autonomous production of parathyroid hormone. After removal of adenoma, one of the surgeons concern is postoperative hypocalcaemia. There is no precise method to determine if patients have hypocalcaemia postoperatively. The purpose of this study was to determine the relation between parathyroid adenoma weights, postoperative serum calcium and...

Background: Cadmium toxicity has been shown in aquatic animals but the effect on frog’s endocrine glands is not known. We investigated the effects of cadmium on ultimobranchial and parathyroid glands of Indian skipper frog, Euphlyctis cyanophlyctis. Methods: Frogs were exposed to cadmium chloride for short and long terms and sacrificed after 24, 48, 72 or 96 h (short-term) and after 5, 10, 1...

In a paper on the autoand isotransplantation, in dogs, of the parathyroid glandules, a the histories of two of the dogs (Nos. 8 and 9) reported in the series of experiments were incomplete, the animals having been kept for further study. One of these dogs (No. 9) was observed for fifteen months and was in good health until the performance of the final operation at which a parathyroid autograft ...

Nuclear diameter was measured and mean nuclear diameter calculated in 18 parathyroid carcinomas. In 11 of the 18 tumours mean nuclear diameter was above the range previously reported for 55 parathyroid chief cell adenomas and provides a useful discriminant in histological diagnosis.

Introduction: Approximately 2% of parathyroid adenomas reside in the mediastinum and are not amenable to the traditional cervical approach. Midline full sternotomy has been frequently used to excise these glands but this approach can be associated with significant morbidity. Methods and results: Midline partial sternotomy to the third intercostal space is a valid alternative surgical approach t...

Parathyroid cysts (PC) are an unusual cause of neck swellings. The majority are nonfunctioning and prove to be a diagnostic challenge given their nonspecific physical and radiological characteristics. This is compounded by their rare occurrence, leading them to be overlooked in the differential diagnosis of neck lumps. Imaging techniques fail to determine the origin of these lesions, but a preo...
