[Malignant hypercalcaemia revealing acute lymphoblastic leukemia: case report].

Malignant hypercalcaemia is a metabolic emergency. Its association with solid tumors is common, whereas it has been rarely described in patients with malignant hemopathies other than multiple myeloma and T-cell leukemias/T-cell lymphomas associated with lymphotropic virus type I (HTLV-I). We here report the case of a female patient with acute lymphoblastic leukemia revealed by malignant hypercalcaemia and pathological fracture of the humerus.
