Also, we found another case with well-differentiated bronchial tumor, which presented with lung mass and hypercalcemia of 14.4 mg/dl, PTH of 4.7 pg/ml, and PTHrP of 109 ng/ml that was treated with 4 mg zolendronic acid every 28 days; then, lobectomy was done, which led to normalized calcium level and decreased PTHrP [17]. This evidence concerns the gene PTHLH and hypercalcemia disease.
