Hypercalcemia is a rare metabolic disorder in course of B cell lymphoma. The mechanism of hypercalcemia in patients with malignancy may include the increased extrarenal production of vitamin D from tumoral cells or neighboring macrophages, i-PTH or PTHrP from tumoral cells. In this case we reported a 34 years old caucasian woman with acute renal failure and hypercalcemia as onset of splenic lymphoma in absence of abnormal levels of serum vitamin D and PTHrP. Because of dramatic recovery of renal function and hypercalcemia after splenectomy, we can speculate that main mechanism of hypercalcemia is related to vitamin D production from neighboring lymphoma macrophages.
