Hypercalcemia is a disorder that most commonly results from malignancy or primary hyperparathyroidism. [1, 2, 3, 4, 5, 6] Other, less common causes of elevated calcium include increased intake or absorption, granulomatous disease, immobilization, and thiazide diuretic use. However, the primary diagnostic approach should be to first rule out underlying malignancy and parathyroid disease. [7]
