• A 58-year-old man was initially seen with fatigue and weight loss. Laboratory examination detected hypercalcemia, elevated 1,25-dihydroxycholecalciferol levels, low parathyroid hormone (PTH) concentrations, and subperiosteal bone resorption. The patient underwent subtotal parathyroidectomy for presumed hyperparathyroidism, but serum calcium and 1,25-dihydroxycholecalciferol levels remained elevated following surgery. Search for another cause of the hypercalcemia disclosed enlarged para-aortic lymph nodes, biopsy specimens of which demonstrated Hodgkin's disease. After treatment of the patient with two cycles of chemotherapy with mechlorethamine hydrochloride, vincristine sulfate, procarbazine hydrochloride, and prednisone, serum calcium, 1,25-dihydroxycholecalciferol, and PTH levels normalized. We speculate that the humoral hypercalcemia in this patient resulted from tumor production of 1,25-dihydroxycholecalciferol.
