Hypercalcemia is commonly associated with solid tumor malignancies, but less often with hematologic malignancies. When present in hematologic malignancies, hypercalcemia is often secondary to overproduction of Vitamin D from the tumor cells. Very few cases with parathyroid hormone related peptide (PTHrP) induced hypercalcemia in B-cell lymphomas have been reported. Here we present a 44 year old male with a history of chronic lymphoctic leukemia who presented with hypercalcemia and an elevated PTHrP, found to have a transformation to Diffuse Large B-cell Lymphoma (DLBCL).
