HBsAg has been sought by light microscopy in liver specimens from patients with
cirrhosis
(79 cases) and hepatoma (99 cases). The study was carried out on fixed material using orcein staining, immunoperoxidase technique and indirect immunofluorescence. HBsAg was detected in the serum by radio-immunoassay (RIA) using Ausria II-125 in 38 patients with
cirrhosis
and in 36 with hepatoma. In the 38 seropositive cases of
cirrhosis
HBsAg-positive cells were observed in 31 (81.6%) by the orcein staining and in 32 (84.2%) by the peroxidase and immunofluorescence staining. Among the 36 seropositive patients with hepatoma, HBsAg was detected in the surrounding non-neoplastic part of the liver, cirrhotic or not, in 30 (83.3%) by orcein staining and in 34 (94.4%) by the immunoperoxidase method and immunofluorescence. Positive solitary-cells were seen occasionally in the
tumor
tissue in 16 cases using orcein, in 9 using peroxidase and in 7 by fluorescence, out of the 36 seropositive patients with hepatoma. The results of this study do not support the hypothesis of a direct oncogenic effect of HBsAg on the liver cells, since this antigen was detected mainly in the non-neoplastic part of the liver tissue and only occasionally in the
tumor
cells. Of the 63 cases of seronegative hepatoma, 3 showed some round orcein-positive inclusion bodies in the cytoplasm of the neoplastic and the non-neoplastic cells; these bodies were not stained by the two immunological methods.

Four cases of hepatic angiosarcoma are reported with a review of 99 other cases in the English literature. Angiosarcoma of the liver is associated with chronic exposure to thorotrast, vinyl chloride, arsenicals, radium and possibly copper and with chronic idiopathic hemochromatosis. Although 40% of patients have hepatic fibrosis or
cirrhosis
at autopsy, the nature of the association between chronic liver disease and hepatic angiosarcoma is unknown. The clinical presentation of hepatic angiosarcoma is nonspecific with abdominal pain, weakness and weight loss common complaints and with hepatomegaly, ascites and jaundice common findings. Liver function tests are usually abnormal but there is no one liver function test or set of tests specific for the
tumor
. The occurrence of thrombocytopenia and disseminated intravascular coagulation is characteristic of hepatic angiosarcoma and may be related to local consumption of clotting factors and formed blood elements in the
tumor
. Catastrophic intraabdominal bleeding is also characteristic and occurs in one-fourth of all cases. This complication is likely related to the high incidence of clotting abnormalities and the vascular nature of the
neoplasm
. Selective hepatic arteriogram and open liver biopsy are the foundations of diagnostic evaluation. Percutaneous liver biopsy should be avoided. Failure to appreciate the possibility of hepatic angiosarcoma in the proper clinical setting, leading to blind percutaneous biopsy, may result in failure to make the diagnosis at the cost of significant morbidity and mortality. Survival of patients with hepatic angiosarcoma is brief; only 3% live longer than 2 years. Treatment of the
tumor
to date is empirical. There are probably a few patients who might benefit from radical surgery with curative intent. For all others chemotherapy is indicated. Adriamycin is active against hepatic angiosarcoma, but optimal dose and mode of administration require further investigation. Further study is also required to delineate the cause of hepatic angiosarcoma in the 60% of cases without definite epidemiologic association.

A man of 37 years of age developed portal hypertension which was observed on radiological examination as a mediastinal opacity having the appearance of a
tumor
. No oesophageal varices were seen on barium meal examination or by endoscopy. A smooth liver was seen during laparoscopy. Pre-operative hemodynamic studies showed that there was no sinus block. Thoracotomy revealed an aneurysm of the azygos veins. Exploratory laparotomy after coelio-mesenteric arteriography confirmed the diagnosis of diffuse nodular hyperplasia of the liver,
cirrhosis
, and portal hypertension. The findings in 16 cases of mediastinal opacity from portal hypertension reported in the published literature are discussed.

There now appears to be a good correlation between long-term steroid treatment and the incidence of liver tumors. Certain changes in the liver cells after steroid treatment have been observed and are of the same nature as changes in livers with
cirrhosis
or viral hepatitis. These 2 diseases are known to have a high liver
tumor
incidence rate. Some steroids are known to be active as cocarcinogenic substances during the growth of liver tumors induced by different carcinogens. Many indices indicate that steroid hormones induce or promote tumors, but the mechanism of action remains unknown. Goldfarb (1976) proposed that these steroids may be lowgrade carcinogens or that they may be converted into carcinogenic compounds through partial degradation by intestinal bacteria or by drug metabolizing systems in hepatocytes. A different model is proposed to clarify the mechanism of steroid action and its relation to the induction of liver tumors. The physiological rate of cell renewal in the lives of adult rats is constant. At any time 1% of the liver cells are in the DNA synthesis phase and 0.001% are in mitosis. During pregnancy or after removal or destruction of liver cells, the rate of cell proliferation increases greatly. The intensity of cell proliferation in the liver of rats depends on the concentration of biologically active corticosterone in the blood. After total adrenalectomy of adult male rats, the corticosterone level in the serum declines in the 1st and 2nd postoperative days from 5 mcg/100 ml of serum to an undetectable amount. The inhibitory effect of the corticosteroids on DNA synthesis in liver cells "in vitro" is well known. It is assumed that corticosterone is an inhibitor of cell proliferation in the liver and that reduction or elimination of corticosterone results in cell proliferation in the liver. Elimination of corticosterone cannot be effected by adrenalectomy in male rats. Theoretically it is shown that the stimulation by progesterone results in inactivation of corticosterone. No significant differences are observed between the corticosterone concentrations in control and pregnant rats, but there is a significant increase of progesterone. The injection of progesterone stimulates mitoses in the liver with the number of mitoses being dependent on the amount and the number of injections of this hormone.

In recent literature numerous papers have been published concerning the accuracy of scintigraphic detection of liver metastases. Unfortunately however, the problem of false positive results is not particularly discussed in these papers. Because of the lack of information it was our aim to compare our own scintigraphic results with postmortem histopathological findings. Our investigations were carried out in 139 patients with various types of malignancy. Included in the investigations were 20 patients with primary liver
tumor
. The interval between scintigraphic examination and the histological verification ranged from 3 days to 1 year. In 62 of the patients with liver metastases, histopathology revealed liver metastases, while 77 patients showed no liver involvement. We arrived at the correct diagnosis "liver metastasis" in 50 out of 62 patients (80.6%). False negative scintigrams (19.4%) were found in most of the respective cases when diffuse malignant involvement such as leukemia and Hodgkin's disease was present, and also when the size of the metastases was less than 2 cm in diameter. Fifty six out of 77 patients (72.7%) without histopathological evidence of liver metastases revealed negative scintigrams. Twenty one (27.3%) false positive scintigrams were mostly due to (diffuse) nonmalignant disease e.g. fibrosis and
cirrhosis
. The overall accuracy of liver scintigraphy in our study was 76.2%. In 18 of 20 (90%) patients with focal liver disease correct diagnosis was established. 7 patients with benign liver tumors and 11 of 13 patients with hepatocellular carcinoma showed focal defects. Considering the fact that liver scintigraphy is a non-invasive procedure, it can be recommended as screening method. In connection with sonography and computer tomography liver scintigraphy can undoubtedly improve the diagnostic accuracy in detecting liver metastases and primary liver tumors.

The value of serum bile acids (SBA) in the diagnosis of hepatobiliary disease has been investigated. A modified GLC method was used, with an overall coefficient of variation of +/- 11% in the control range. Serum was obtained after a 12 hour fast, and two hours after a fatty meal from 73 patients and 14 control subjects. In controls the total fasting SBA of 2.17 +/- 0.86 mumol/l increased significantly (p less than 0.001) to 3.81 +/- 1.14 mumol/l after a meal. All icteric patients had raised SBA, but in 23 anicteric patients there was no significant difference in the detection of chronic liver disease by fasting SBA, postprandial SBA, AST, or gamma GTP. Compared with controls, serum in patients contained proportionately less deoxycholic acid (p less than 0.001), there was proportionately more cholic acid in extrahepatic obstruction (p less than 0.001), and proportionately more chenodeoxycholic acid in patients with
cirrhosis
, viral hepatitis, and
neoplasia
(p less than 0.001). In control subjects, the fasting cholic:chenodeoxycholic acid ratio ranged from 0.5-1.0, and differed significantly (p less than 0.001) from patients with extrahepatic obstruction 0.96-3.6, and
cirrhosis
0.1-0.5. It is concluded that serum bile acids measured by sensitive methods can provide useful diagnostic information.

We prospectively evaluated risk factors in 1000 consecutive patients who underwent liver biopsy: 829 outpatients and 171 inpatients. The two groups were similar except that the outpatient group had a higher percentage of patients with hepatitis-
cirrhosis
and a lower percentage with
neoplasia
when compared with the inpatient group (P less than 0.01). The inpatient group had more relative contraindications (P less than 0.01). Among the 1000 patients, none died and none required laparotomy. If moderate to severe pain or hypotension or both developed (5.9%), they first became manifest during a 3-hr period of observation after biopsy. Forty-four outpatients (5.3%) were hospitalized; 39 were dismissed within 36 hr and 5 within 4 days. Complications were more often experienced by those with relative contraindications (P less than 0.05) and increased number of passes (P less than 0.01). Inpatients with hepatitis-
cirrhosis
experienced more complications (P less than 0.05) than did patients with other diagnoses (12.8 versus 3.8%). Complications were not related to type of needle, site of entry, or experience of operator. Liver biopsy as an outpatient procedure is safe if facilities are available for 3 hr of observation and hospital support; 5% of patients will require immediate hospitalization.

In a review of 906 consecutive liver biopsies, sinusoidal dilatation, unrelated to passive congestion of the liver, sinusoidal infiltration, or
cirrhosis
, was found in 26 cases (2.9%). In 21 of them the final diagnosis was a neoplastic or granulomatous disease (tuberculosis, brucellosis, Crohn's disease), but in only half of them was there evidence of neoplastic or granulomatous infiltration of the liver. In the remaining cases, sinusoidal dilatation was either the only histological abnormality or it was associated with nonspecific changes. Although the pathogenesis of sinusoidal ectasia is not known, our findings indicate a definite relationship to the presence of
tumor
or granulomatous disease in the liver or elsewhere in the body. It is concluded that the finding of sinusoidal dilatation as an isolated histological change in a liver biopsy specimen should prompt the search for a
tumor
or a disease associated with granulomas.

Arteriovenous shunting in the liver is a rare angiographic finding. Review of the literature shows that most cases are related to trauma or
neoplasm
. The authors discuss several entities which should also be included in the differential diagnosis, among them congenital arteriovenous malformations or hemangiomas of the liver and pancreas,
cirrhosis
with rearterialization of the liver, hepatic abscess, hypervascular liver metastases, and primary tumors with invasion of the portal and hepatic veins by arterial neovasculature.

Evaluation of stored iron by means of DFOX-induced sideruria in 101 subjects with various degree of hyposideraemia with or without anaemia, is reported. Three groups were examined: 49 patients with chronic loss of blood and malabsorption and urinary iron values up to 1 mg/24hr; 43 with non-bleeding
neoplasia
, collagen disease, lymphoma,
cirrhosis of the liver
etc. and values of 1-2mg/24 hr; 9 with rheumatoid arthritis and
cirrhosis of the liver
and values over 2 mg/24 hr. The reasons why hyposideraemia may accompany incipient of frank tissue hypo-, normo- or hypersiderosis are discussed.
