SARCOIDOSIS WITH HYPERCALCEMIA - SUCCESSFUL TREATMENT OF RENAL-INSUFFICIENCY AND RENAL CALCIFICATION WITH PREDNISOLONE

A case of muscular sarcoidosis accompanied by severe hypercalcemia (se rum calcium 15.5 mg/dl), renal insufficiency and renal calcification i s reported. Sarcoid granulomas were found in the biopsy specimens of t he lung and the muscle. The administration of prednisolone effectively improved not only muscle weakness but also hypercalcemia, renal insuf ficiency and renal calcification. This is a rare case of sarcoidosis i n which renal calcification remitted after treatment with prednisolone . It is thus suggested that prednisolone treatment should be considere d not only for hypercalcemia, but also for renal insufficiency caused by renal calcification in patients with sarcoidosis.
