abstract: BACKGROUND
  Lung cancer is the leading cause of death among the cancers seen in the United States. Hypercalcemia and leukocytosis are two common paraneoplastic syndromes associated with lung cancer. Unfortunately patients presenting with Hypercalcemia- leukocytosis syndrome has a worse prognosis than patients presenting with lung cancer alone.
