A case of sclerosing hepatocellular carcinoma (SHCC) with hypercalcemia was reported. Clinical studies revealed a tumor at the liver hilum with invasion into the bile duct. Light microscopy of the tumor disclosed a moderately differentiated hepatocellular carcinoma (HCC) of the trabecular type with diffuse fibrous stroma. Abundant dense granules were observed in the cytoplasm of the tumor cells with electron microscopy. The elevated serum calcium (13.9 mg/dl) returned to the normal range after resection of the tumor.
