We experienced a 68 years-old male who had frequent hypoglycemic attacks. The diagnosis of a giant hepatoma associated with hypoglycemia was established by oral glucose tolerance test (O-GTT), angiography and computed tomography. The cavography demonstrated the invasion or depression of the tumor. It was ascertained by an operative exploration that the tumor occupied most of the right trisegments of the liver and infiltrated into a part of the left lateral segment. The right hepatic trisegmentectomy along 1.5cm left side line apart from the falciform ligament was performed. Resected tumor showed 11 x 13 x 10cm in size and 1200g in weight. Microscopic findings demonstrated hepatocellular carcinoma as Edmondson's Type II.
After the operation, this patient became free from the hypoglycemic attack. A fasting blood sugar became within normal limits and O-GTT demonstrated a normal blood sugar level and insulin response. No concentration of immuno-reactive insulin was found in the resected tumor, however, the blood sugar in rats which received the intravenous injection of the tumor extracts was remarkably decreased in 20 minutes. From these observation, hypoglycemia in this patient seemed to depend mainly on the factor of insulin-like activity of the tumor.
In the literature, the hepatocellular carcinoma associated with paraneoplastic phenomenon, e.g. hypoglycemia, has rarely been resected because of accompanied liver cirrhosis or giant size of the tumor. This is the second patient in our country in whom the tumor was fortunately resected and the paraneoplastic syndrome disappeared postoperatively.
