All possible causes must be considered in a patient with hypercalcemia. The association between both benign or malignant thyroid disease and primary hyperparathyroidism is well recognized. Up to 65% with primary hyperparathyroidism have associated thyroid abnormality. Hypercalcemia has also been associated with many malignant conditions. But, it is rarely seen in digestive tract cancer, such as carcinoma of gallbladder. Hypercalcemia syndrome is an absolutely rare entity. It is coexisting with hyperthyroidism, primary hyperparathyroidism and cancer of the gallbladder.
