title: Hypercalcemia as an early sign of lymphoma in a patient with acquired immunodeficiency syndrome (AIDS).
abstract: Hypercalcemia is uncommon in patients infected with the human immunodeficiency virus (HIV). It has been described in association with cytomegalovirus infection, Pneumocystis carinii pneumonia, granulomatous diseases, and lymphoma. However, symptomatic hypercalcemia as an early sign of an underlying AIDS-related lymphoma is not well documented. We discuss the case of a patient with HIV and hypercalcemia, leading to the diagnosis of an underlying lymphoma. The hypercalcemia was associated with a suppressed serum level of intact parathyroid hormone and a normal serum phosphorus level. The possibility of a lymphoproliferative disorder should be considered in the differential diagnosis of HIV-associated hypercalcemia.
