Hypercalcemia complicating malignancy is a rare complication in pediatric age group. In
this article, we present a case with acute lymphoblastic leukemia presenting as severe hypercalcemia. A
10 years old girl presented with an acute onset of fever, nausea, vomiting, loss of weight, costovertebral
pain and frequency. She was admitted with a presumptive diagnosis of acute pyelonephritis. Her
examination showed mild hepatosplenomegaly. In laboratory studies she had sever hypercalcemia.
Despite the absence of circulating blasts, bone marrow aspiration was diagnostic of acute lymphoblastic
leukemia. The hypercalcemia was initially treated with intravenous hydration and furosemide but the
serum calcium level normalized only after the beginning of specific chemotherapy. Hypercalcemia
represents an emergency in children, and acute leukemia must be considered in differential diagnosis
even when there are no circulating blasts.
