Hypercalcemia mediated by parathyroid hormone-related protein as an early manifestation of pancreatic adenocarcinoma metastasis: a case report.
Humoral hypercalcemia of malignancy (HHM) is a paraneoplastic syndrome rarely associated with pancreatic adenocarcinoma. Parathyroid hormone-related peptide (PTHrP) is the central mediator of this condition. In our patient, hypercalcemia associated with elevated PTHrP was the initial manifestation of metastatic pancreatic adenocarcinoma. Successful palliation of HHM with bisphosphonates and loop diuretics has been previously reported and was effective in our patient. We report the first case of pancreatic adenocarcinoma metastasis after successful resection to present with hypercalcemia.
