Context. Severe hypercalcemia is a life-threatening condition. Atypical parathyroid adenoma and parathyroid carcinomas are uncommon causes which can be difficult to differentiate. Objective. We report a case of a 36-year-old male with very high serum calcium due to a possible atypical parathyroid adenoma versus parathyroid carcinoma. Case Illustration. A serum calcium level of 23.2 mg/dl was no...
We describe a 59-year-old woman who presented with pathological osteoporosis, cerebral infarction, hypercalcemia, and markedly high parathyroid hormone levels. The diagnosis was primary hyperparathyroidism, and parathyroidectomy was performed. Histopathological examination showed parathyroid adenoma. Surgical exploration for recurrent parathyroid carcinoma was undertaken at 2 and 3 years after ...
The case is reported of a woman who died at the age of 36 from parathyroid carcinoma. The removal, seven years earlier, of a large parathyroid tumour, judged at that time to be benign, was followed by a remission of symptoms for about four years after which they recurred. At necropsy, a well-differentiated parathyroid carcinoma showed local invasion and lymph-node metastases in the neck. Review...
Parathyroid carcinomas are rare endocrine tumors which comprise 0.3-5.6% of all causes of hyperparathyroidism. 90% of them are hormonally active, while 10% of them may be non-functional. They mostly occur in a single parathyroid gland. Concurrent involvement of both parathyroid glands is quite rare. A 57-year-old male patient was admitted to emergency department with the complaint of dyspnea. T...
Parathyroid carcinoma is a rare cause of hypercalcemia. Hypercalcemic crisis is a medical emergency. Hemodialysis is rarely needed to treat hypercalcaemia. We report a case of refractory hypercalcaemia secondary to parathyroid carcinoma requiring haemodialysis.
To the Editor, Parathyroid carcinoma is a rare disease that accounts for less than 1% of all hyperparathyroidism [1]. The incidence of parathyroid carcinoma is extremely low, although the apparent incidence of hyperparathyroidism increased after the introduction of multi-channel autoanalyzers. If increased serum calcium and parathyroid hormone (PTH) levels are sustained postoperatively, metasta...
Parathyroid gland carcinoma is a rare malignancy. The tumor is mostly functioning, causing severe hyperparathyroidism, with high serum calcium level and severe bone disease. Non-functioning parathyroid carcinomas are extremely rare. We report on a 60-year-old male patient admitted to ENT Department due to a large neck tumor mass compressing the thyroid and trachea. Preoperatively, thyroid hormo...
Parathyroid carcinoma is rare; accounting for 1% of all the causes of primary hyperparathyroidism. When the tumor is no longer amenable for surgery, medical therapy to control the hypercalcemia becomes the main focus of management. Unfortunately, parathyroid carcinoma mediated hypercalcemia is often severe and more resistant to medical therapy. We report a case of parathyroid carcinoma with ref...
This study reported a family with primary hyperparathyroidism due to parathyroid carcinoma and investigated the pathological and genetic features of family members. Three members of the family had clinical manifestation of primary hyperparathyroidism and tumors in the neck. All three patients underwent parathyroidectomy, thyroidectomy and level-VI neck dissection and were definitively diagnosed...
The chance of an intrathyroidal occurrence of a parathyroid gland is about 1-3%. Among the causes of hyperparathyroidism, parathyroid cases occur in less than 1% of patients. Here we present the case of a 63 year old Saudi female suffering from an intrathyroidal parathyroid carcinoma. The suspicion coming from the clinical investigations that the removed tumor tissue may be a parathyroid carcin...
