We report the first documented occurrence of hypercalcemia due to excessive production of calcitriol in acute myeloid leukemia (AML). The patient presented with severe hypercalcemia and renal failure accompanying a new diagnosis of AML. This extremely rare AML complication proved refractory to conventional hypercalcemia treatments but responded promptly to chemotherapy. Subsequent PCR studies performed on the leukemia blasts for vitamin D-related genes revealed dramatic up-regulation compared to healthy CD34+ cells and other primary AML cells. Recent data highlight a role for vitamin D in hematopoietic cell proliferation. Accordingly, this case may highlight another aspect of molecular heterogeneity in AML.
