Evaluation and aetiopathogenesis of hypercalcaemia. A study of 89 patients

Eighty nine cases with hypercalcaemia were seen during the period 1975-87. Malignancy of nonparathyroid tissue was responsible in 72 cases (80.9%). The other causes were primary hyperparathyroidism (11 cases), hypervitaminosis D (5) and sarcoidosis (1). Every patient with hypercalcaemia needs careful evaluation to establish the aetiological basis so that specific treatment may be instituted.
