title: [Hypercalcemia in sarcoidosis].
abstract: In a 56-year-old man hypercalcaemia and kidney function impairment were the presenting symptoms of sarcoidosis. The diagnosis was supported by the finding of elevated 1,25-dihydroxyvitamin D levels and of a cluster of epithelioid macrophages in aspirated bone marrow. By exclusion of other granulomatous diseases and a favourable reaction of the hypercalcaemia and renal function to treatment with prednisone the diagnosis was confirmed. The relationship between the autonomous extrarenal production of 1,25-dihydroxyvitamin D and the hypercalcaemia is discussed.
