Primary hyperparathyroidism: presentation and management.

164 hypercalcemic patients were examined to determine the co-relation, frequency and mode of presentation of primary hyperparathyroidism. Primary hyperparathyroidism was diagnosed in 11 patients (6.7%). All of them presented late with renal and bony complications. The incidence of primary hyperparathyroidism appears to be lower than that of the western countries, and the introduction of routine serum calcium estimates can be expected to yield more cases of primary hyperparathyroidism especially asymptomatic cases.
