title: An autopsy case of cholangiocarcinoma with hypercalcemia.
abstract: Au autopsy case of cholangiocarcinoma which showed clinically hypercalcemia and hypophosphatemia without bone metastases is presented in this report. Although parathyroid hormone (PTH)-like substance of 520 ng/g. dry weight was measured in neoplastic tissue by the radioimmunoassay, membrane-limited secretory granules as those of parathyroid gland were not found in the fine structure. The significance of an existence of secretory granules in ectopic PTH producing tumor is discussed.
