Hypercalcemia and reversible renal failure in heavy-chain disease

We have reported a case of gamma heavy-chain disease associated with hypercalcemia and reversible renal failure. After combined chemotherapy the patient remains well after 21 months of follow-up, and serum calcium levels remain in the normal range. This case supports the notion of Kyle et al that heavy-chain disease may present a diverse picture, and documents the first use of aggressive combination chemotherapy in the management of associated moderately severe hypercalcemia and hypercalcemic renal failure.
