[Leukemia and hypercalcemia (author's transl)]

Two cases of childhood leukemia with hypercalcemia are reported. In the first case who died by acute granulocytic leukemia, autopsy showed a generalized calcinosis. The other case was an acute lymphocitic leukemia with hypercalcemia and destructive lessions of bones with pathologic fractures. Response to chemotherapy was good. Literature about mechanismes which can induce hypercalcemia in malignancy is reviewed.
