• We treated a case of hypercalcemia and primary liver tumor and reviewed a series of such cases treated at the Mayo Clinic (Rochester, Minn). Primary tumor of the liver was diagnosed in 192 patients (152 had hepatocellular carcinomas; 40, cholangiocarcinomas) between 1969 and 1980. Hypercalcemia of unknown cause was found in eight patients with hepatocellular carcinoma (5.3%) and seven with cholangiocarcinoma (17.5%). Five hypercalcemic patients had serum immunoreactive parathyroid hormone values consistent with ectopic hyperparathyroidism. An additional five patients had high serum calcium, low phosphate, and low chloride concentrations that met Lafferty's criteria for pseudohyperparathyroidism. Our results suggest that hypercalcemia associated with primary hepatic tumors is relatively common, and incidences vary according to the type of primary tumor. Hypercalcemia may be controlled when surgical excision of the primary tumor is possible.
