[Major hypercalcemia revealing sarcoidosis].
We reported a new case of sarcoidosis disclosed by a symptomatic severe hypercalcemia. Increase of 1,25-dihydroxyvitamin D is secondary to an extrarenal production by alveolar macrophages and sarcoid granuloma. Glucocorticoid administration produces a prompt and persistent decrease in serum and urinary levels of calcium.
