title: Hyperparathyroidism accompanying multiple myeloma.
abstract: Hypercalcemia is a manifestation of a variety of both benign and malignant diseases. These conditions are not mutually exclusive, and we present a case report of a patient first diagnosed with the classic findings of multiple myeloma who, after appropriate therapy, demonstrated persistent hypercalcemia and was found on further testing to have an elevated parathormone level (PTH) and scintigraphic evidence of a benign parathyroid adenoma. Hypercalcemia responded to excision of the parathyroid adenoma. There are only 18 similar cases reported in the medical literature.
