Acute pancreatitis with hypercalcemia caused by primary hyperparathyroidism associated with paraneoplastic syndrome: A case report and review of literature

Figure 2 The serum concentration of amylase, calcium, and intact parathyroid hormone during the disease course of this patient. The serum amylase gradually recovered to normal level whereas the intact parathyroid hormone concentration decreased after exploratory parathyroidectomy, which was performed 25 d after admission. Refractory hypercalcemia ultimately decreased to normal level after cytoreductive surgery on May 11. PTH: Parathyroid hormone.
