We report sarcoidosis-related hypercalcemia in a patient undergoing hemodialysis, The patient, a 54-year-old woman, had been undergoing maintenance hemodialysis since 1989. The cause of end-stage renal disease was membranoproliferative glomerulonephritis. The patient was admitted to our hospital in January 2002 for the treatment of hypercalcemia(13.5 mg/dl), which was diagnosed in December 2001. Chest X-ray showed bilateral hilar lymphadenopathy, chest CT scan showed mediastinal lymph node swelling, and Ga-scintigraphy showed abnormal accumulation of gallium in the mediastinum. The patient's intact-PTH was 80-100 pg/ml. ACE(31.4 IU/l) and 1.25(OH)2D3(85 pg/ml) were elevated, and the bronchial lavage fluid CD4/CD8 ratio was slightly elevated. Epitheloid granulomatous tissue was obtained from a subclavian lymph node biopsy. Thus, the patient was diagnosed with sarcoidosis. The hypercalcemia and bilateral hilar lymphadenopathy improved with corticosteroid therapy.
