Hiperkalsemi ve ？oklu Patolojik Kemik Fraktürü ile Ba？vuran Akut Lenfoblastik L？semi

Hypercalcemia is common in some lymphoproliferative disorders, but is a rare complication of acute lymphoblastic leukemia in childhood. We report a 8-year-old boy who presented with hypercalcemia and multiple pathologic bone fracture was diagnosed to have acute lymphoblastic leukemia. All the disorders that could be the reason of hypercalcemia and the laboratory tests were within normal limits. Hypercalcemia was treated with intravenous isotonic sodium chloride solution, furosemide and biphosphonates. Hypercalcemia may be a presenting laboratory finding of acute lymphoblastic leukemia in childhood. Repeat laboratory and peripheral blood smear examinations are important for differential diagnosis of hypercalcemia
