Vitamin D deficiency masking primary hyperparathyroidism.
Hannan FM., Fairney A., Johnston DG.
Vitamin D deficiency and primary hyperparathyroidism (PHPT) are relatively common disorders. The coexistence of these conditions should be considered, as depletion of vitamin D may alter the clinical expression of autonomous parathyroid disease. We report details of a vitamin D deficient patient in whom replacement therapy led to the unmasking of occult PHPT.
