Parathyroid carcinoma. A report of five cases

Area of Science:

• Endocrinology
• Surgical Oncology
• Pathology

Background:

• Parathyroid carcinoma is a rare endocrine malignancy.
• It accounts for 0.5-4.0% of hyperparathyroidism cases.
• This study reviews a single institution's experience.

Purpose of the Study:

• To report on the clinical course and outcomes of parathyroid carcinoma.
• To analyze survival and morbidity in patients with this rare tumor.
• To highlight the challenges in managing parathyroid carcinoma.

Main Methods:

• Retrospective review of five parathyroid carcinoma cases.
• Analysis of patient demographics, clinical presentation, and pathological findings.
• Evaluation of surgical outcomes and long-term follow-up.

Main Results:

• Five cases of parathyroid carcinoma (1.1% of primary hyperparathyroidism) were identified.
• All patients were female, aged 29-60, with severe hypercalcemia.
• Three patients died from recurrent disease; two achieved long-term normocalcemia post-resection.

Conclusions:

• Parathyroid carcinoma, though rare, carries significant morbidity and mortality.
• Local recurrence and metabolic disturbances are primary causes of death.
• Successful resection can lead to long-term survival and normocalcemia.
