Parathyroid carcinoma with hypercalcemia

Parathyroid carcinoma with hypercalcemia refers to a severe endocrine state arising from a rare, malignant neoplasm of the parathyroid glands that autonomous hypersecretes parathyroid hormone This malignancy accounts for a small fraction of primary hyperparathyroidism cases, typically presenting in middle-aged adults without a marked sex predominance

Parathyroid carcinoma with hypercalcemia refers to a severe endocrine state arising from a rare, malignant neoplasm of the parathyroid glands that autonomous hypersecretes parathyroid hormone Pathophysiologically, the tumor drives unrestrained osteoclastic bone resorption and renal calcium reabsorption, resulting in profoundly elevated serum calcium concentrations

This malignancy accounts for a small fraction of primary hyperparathyroidism cases, typically presenting in middle-aged adults without a marked sex predominance Clinically, affected patients frequently exhibit pronounced constitutional fatigue, cognitive changes, nephrolithiasis, renal dysfunction, and fragile bone disease, with unregulated hypercalcemia representing the predominant source of morbidity and mortality
