1/367. Intact PTH-producing hepatocellular carcinoma treated by transcatheter arterial embolization.

    We report a case of hepatocellular carcinoma with hypercalcemia. There was no evidence of bone metastasis or increase in parathyroid hormone-related protein. The serum level of intact parathyroid hormone (intact PTH) was very high, and the results of the hepatic venous sampling suggested that the tumor produced intact PTH. Transcatheter arterial chemoembolization effectively controlled the humoral hypercalcemia.

2/367. Epithelioid hemangioendothelioma with solitary bone location associated to multiple lung and liver lesions. A case report.

    Progressive development of a lobulated osteolytic lesion of the left calcaneus was observed in a 28-year-old woman. The bone tumor was associated with multiple lung nodules and later with a few small nodular liver lesions. A histological and immunochemical diagnosis of epithelioid hemangioendothelioma was obtained by bone tumor resection and thoracoscopic lung biopsy. Imaging aspects are reported with emphasis on its multifocality.

3/367. neuroblastoma metastatic to the liver in infants.

    Four infants are described who presented with rapid enlargement of the liver. This was found to be due to neuroblastoma which had metastasized to the liver; the condition was associated with high levels of urinary vanillylmandelic acid (VMA). In 3 infants the primary tumour was in the adrenal gland and in one it was not identified. One infant died after laparotomy and 2 infants survive disease free with normal VMA levels, one after adrenalectomy and hepatic irradiation and one after a short course of chemotherapy. The fourth patient responded initially to hepatic irradiation and chemotherapy, but relapsed 2 years later with recurrent disease; at the same time the VMA level which had been normal, again rose. The importance of screening for an abnormal VMA level in any infant with a rapidly enlarging liver in order to obtain an early diagnosis is stressed. Careful follow-up, with serial VMA estimations, is essential to detect recurrent disease. The prognosis for some infants with this distribution of neuroblastoma which has metastasized to the liver, but not to the bones or oribt, is good.

4/367. A case of hepatocellular carcinoma with bone metastasis responding to radiotherapy after successful hepatectomy of primary lesion.

    Radical hepatectomy was carried out on a patient with hepatocellular carcinoma (HCC) located in segment VIII of the liver. The patient was a 56-year-old man who showed positive for hepatitis c antibody and negative for hepatitis b surface antigen. Six months after hepatectomy, a lumbar plane X-ray and computed tomography examination revealed bone metastases in the lumbar vertebrae. The patient was subsequently treated by radiation to the lumbar vertebrae in response to lumbago. The metastatic lesion has been well controlled by radiotherapy on an outpatient basis with no recurrence for 5 years and 3 months. The prognosis of patients with HCC with distant metastases is poor. It is believed that the long survival of this patient can be attributed to successful radiotherapy of the bone metastasis after hepatectomy and the lack of recurrence in the liver.

5/367. A long-term survival patient with advanced gallbladder cancer massively metastasizing to the liver.

    A case of gallbladder carcinoma was reported. A 42-year-old woman was admitted with epigastralgia. Abdominal ultrasonography, computed tomography, and other diagnostic modalities suggested gallbladder carcinoma with multiple liver metastases. These findings indicated no surgical procedure because of the advanced nature of her disease. After the hepatic arterial chemoinfusion therapy, her multiple liver metastatic lesions showed a decrease in size and number. Therefore, extended left lobectomy of the liver with gallbladder and bile duct resection were performed. Five years after initial operation, a solitary liver metastatic lesion (S5) was diagnosed by ultrasonography. Partial resection of the liver was performed for the liver metastasis, and her postoperative recovery was uneventful and had a good follow-up course. One year after the second operation bone metastases occurred, therefore, peroral administration of UFT (tegafur uracil) and radiation therapy for the metastatic lesions of sternum and lumbar vertebra (L1) were performed.

6/367. Bone agent localization in hepatic metastases.

    We present the bone scintigrams of two patients, which demonstrate diffuse extraosseous uptake of a bone agent in metastatic masses in the liver, one from a primary lung tumor and one from a primary breast tumor. The bone imaging agent did not localize in the brain metastases in these patients. CTs of the abdomen in both patients showed massive metastases in the liver with multiple areas of tumor necrosis. The CT of the abdomen of the breast cancer patient showed multiple small hepatic calcifications. autopsy revealed massive tumor necrosis with calcifications in the enlarged liver. In routine bone scintigraphy, diffuse uptake of bone agents in the liver of a patient with a known malignancy should be considered suggestive of massive hepatic metastases.

7/367. Multiple extra-bone accumulations of technetium-99m-HMDP.

    Bone scintigraphy was performed on a woman 2 y and 10 mo after surgery for rectal cancer. Intense extra-bone accumulations of 99mTc-HMDP were visible in an aortic atherosclerosis lesion and in a metastatic liver tumor. Uptake in the metastatic lesion was confirmed by x-ray CT. Uptake in the aortic lesion was shown as typical calcification by x-ray CT.

8/367. motilin-producing liver and bone metastases evidenced 14 years after resection of a rectal polyp.

    A 62-year-old man with a history of a resected rectal polyp was diagnosed 14 years later with right liver and multiple bone metastases. The liver biopsy showed a malignant epithelial tumor that was positive for neuron-specific enolase immunostaining and negative for chromogranin. Electron microscopy was characteristic of that for an endocrine tumor. Most circulating hormonal peptide levels were within normal ranges and only motilin level was elevated. On the right hepatectomy, the three large metastases had a histologic picture suggestive of an endocrine tumor. immunohistochemistry revealed in some areas numerous tumor cells expressing motilin, and a few cells were strongly positive for pancreatic polypeptide and somatostatin. The retrospective analysis of the rectal polyp showed a similar histology and immunohistochemical profile, indicating that this lesion was the primary tumor. motilin-positive cells from one of the hepatic lesions were identified on semithin sections and further processed for electron microscopy. Neurosecretory granules were numerous in all cells. Immunoelectron localization enabled us to characterize the motilin-containing neurosecretory granules, which had a mean diameter of 168.3x38.1 nm. Although not all tumor cells were motilin-positive, a diagnosis of motilinoma for the rectal polyp and its hepatic and bone metastases was proposed.

9/367. Hepatocellular carcinoma with metastasis to the rib complicated by hemothorax. An autopsy case.

    A 64-year old man was admitted to our hospital with multiple hepatocellular carcinoma (HCC) lesions in the liver, lung and bone. Three weeks after admission, the patient became complicated with right upper chest pain. A chest radiograph showed a marked increase in right pleural effusion. Thoracentesis demonstrated a hemothorax. Despite treatment with a continuous pleural tap and blood transfusions, the patient's clinical status worsened and he developed severe dyspnea. His right pleural effusion might be considered to be caused by a rupture of the HCC metastasis in the right 2nd rib. The patient died due to respiratory and hepatic failure 26 hours after his occurring the pleural effusion. An autopsy revealed moderately differentiated HCC in the liver, lung and bone. The HCC metastasis of the right 2nd rib was found to have torn the nearby pleura. We described a rare case in which hemothorax was caused by a ruptured rib-based HCC.

10/367. Thrombotic microangiopathy associated with reactivation of human herpesvirus-6 following high-dose chemotherapy with autologous bone marrow transplantation in young children.

    Thrombotic microangiopathy (TMA) is a serious complication of BMT. Several factors are important in the etiology of TMA, such as cyclosporin A, GVHD, irradiation, intensive conditioning chemotherapy and infection, which cause damage to vascular endothelial cells leading to activation of these cells. We describe two young children with TMA following high-dose chemotherapy with autologous BMT. Development of TMA was accompanied by reactivation of HHV-6, which was identified by both an increase in the copy number of HHV-6 dna in the peripheral blood and a significant increase in antibody titers to HHV-6. Thus, it was suggested that reactivation of HHV-6 together with high-dose chemotherapy played an important role in the pathogenesis of TMA in these patients. Since HHV-6 is known to infect vascular endothelial cells, and CMV which is virologically closely related to HHV-6, has been reported to be a pathogen that causes TMA, infection with HHV-6 of vascular endothelial cells may induce TMA via damage and activation of these cells.
