Hypercalcemia developed in a 34-year-old woman with a clear cell carcinoma of the ovary. Osseous involvement with the tumor cells was not present. Primary hyperparathyroidism was absent. Operative partial resection of the metastatic supraclavicular lymph node, followed by radiation therapy, decreased her serum calcium concentrations. This case belongs to the category of humoral hypercalcemia of malignancy (HHM). Detection of a significant quantity of immunoreactive parathyroid hormone-related protein (PTH-rP) in the metastatic lymph node suggested that the HHM of the patient was induced by PTH-rP produced by the tumor. From a review of 17 cases of ovarian tumors showing HHM-like morbidity, it was found that clear cell carcinoma and cystadenocarcinoma were the major types of ovarian tumors associated with HHM.
