34 pituitary adenomas were examined by light and electron microscopical methods. Slices of tumor tissue fixed in formaldehyde or Bouin's solution, respectively, and embeded in paraffin were stained by hematoxylin-eosin, Goldner's method (including Orang G), periodic acid Schiff (PAS) reaction, and in some cases by Herlant's tetrachrom. The ultrastructure was studied using tumor tissue fixed in glutaraldehyde within 1 hour after removal. The adenomas were classified by their light microscopical characteristics as chromophilic or chromophobe tumors. Employing the PAS reaction and Goldner's staining method, 27 adenomas were found to give intense or weak staining reactions. By electron microscopical investigation , all the adenomas studied were seen to contain secretory granules more or less densely packed within the cytoplasm. The number of these granules was strongly correlated with the intensity of the tinctorial properties of the tumor tissue. Out of 11 acidophilic adenomas, 10 were observed consisting of typical STH cells. 4 acromegalic patients were found to possess heavily or poorly granulated STH cell adenomas (two patients in each of these groups). One patient with a clinical history of liver cirrhosis and gynecomastia was observed bearing an acidophilic (and erythrosinophilic) adenomatous hyperplasia of prolactin cells, 13 tumors consisted of cells exhibiting almost weak amphophilic staining properties and secretory granules of 100-250nm diameter, thus resembling cells which have been reported to produced ACTH. One of the patients suffering from these adenomas, showed the clinical signs of M. Cushing. By ultrastructural criterions, 3 adenomas with PAS-positive tumor cells were considered to be composed of gonadotropic cells. Only 7 adenomas were observed which did not give any chromophilic reaction. These tumors consisted of extreme poorly granulated cells which could not be significantly associated with one of the pituitary hormones by their morphological properties. In respect of the abundance of mitochondria, 4 out of the adenomas were designated as oncocytic tumors.

Prolactin responses to provocative thyrotropin-releasing factor (TRH) stimulation were evaluated in 43 chronic alcoholic men were divided into groups for analysis based on the presence or absence of gynecomastia and the histologic appearance of their livers as determined by percutaneous liver biopsy. Compared to the normal volunteers, alcoholics with reversible liver disease (fatty liver) had reduced basal prolactin levels and exaggerated TRH responses. In contrast, alcoholics with cirrhosis and gynecomastia had markedly elevated basal prolactin levels and reduced responses to TRH. The results of this study combined with previously reported findings in cirrhotic men provide a basis for a possible explanation for the signs of feminization frequently found in alcoholic men.

Eleven specimens of breast lesions obtained from 10 male patients were analyzed for estrogen receptor protein (ERP). Three patients (ages 49, 77, 82 years) had infiltrating duct carcinomas with no axillary metastases. ERP in each of these was positive. Eight specimens with gynecomastia, one of which was obtained from the 77-year-old patient with carcinoma in the same breast, were also analyzed. Of these ERP was positive in a 59-year-old man who had cirrhosis of the liver; two patients with borderline ERP had hepatitis and testicular seminoma, respectively. No relationship between histopathologic features of the lesions and ERP results was found and it is too early to relate these ERP studies to prognosis in these patients. Review of available literature, including our cases, reveals that six of eight male breast carcinomas were ERP-positive.

A significant increase of basal plasma prolactin levels (radioimmunoassayed) in 75 patients with liver cirrhosis was found in comparison to 50 male controls (8.5+/-4.5 (SD) vs. 5.5+/-1.7 ng/ml p less than 0.001). The extent and incidence of hyperprolactinaemia in 48 patients with alcoholic cirrhosis was more pronounced than in 27 cases of cirrhosis of non-alcoholic aetiologies (mean 9.7+/-4.8 vs. 5.7+/-2.1 ng/ml). No relation to ascites formation as well as to the development of gynaecomastia was apparent. Prolactin release following thyrotropin-releasing hormone was markedly enhanced in alcoholic as compared to non-alcoholic cirrhosis. Possibly hyperprolactinaemia and increased pituitary hormone reserve reflects hyperoestrogenism but changes of the hypothalamic regulation cannot be excluded as yet.

Blood levels of estradiol, testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), sex steroid binding globulin (SSBG), and free steroids were surveyed in 117 men to define the pattern of hormonal abnormalities and to examine the relationships between the hormone levels and the development of the endocrine features of cirrhosis. When compared with healthy men of similar ages, the patients had significantly lower metabolic clearance rates (p .001), testosterone production rates (p .001), total and free levels of testosterone (p .001), reduced testosterone responses to human chorionic gonadotropin (HCG) stimulation, higher estradiol, LH, and FSH levels, and higher binding capacities of SSBG. The metabolic clearance and plasma production rates of estradiol were not markedly different from those of controls. Severely ill patients with liver failure of hemochromatosis had low levels of LH and FSH respones to clomiphene and LH-releasing hormone. Patients with gynecomastia and spider naevi had higher estradiol levels than in those without these signs. Longitudinal studies indicated that the hormonal levels, endocrine features, and severity of the liver disease could change independently. It is concluded that the clearance of estradiol from plasma is normal in most patients with liver disease and that reduced degradation of estrogens is not the initial event in the sequence leading to the hormonal abnormalities of cirrhosis. Usual findings of liver failure are elevated gonadotropin levels and a poor Leydig cell response to HCG which suggest that the hypogonadism is primary in most patients with cirrhosis. Discrepancies in the expected relationships between the hormone and clinical changes suggest that other factors than those studied are also involved in the genesis of hepatic cirrhosis.

Literature on the role of estrogens in men is reviewed. The primary active estrogens in males and females are estradiol-17beta (E2), estrone (E1), and estriol (E3). The active constituents of serum E2 and testosterone (T) are those which are not bound by testosterone-estrogen binding globulin (TEBG). The concentration of TEBG is stimulated by estrogen and suppressed by androgens. Both E1 and E2 appear to be derived from the peripheral metabolism of T and androstenedione. The metabolism and physiological roles of estrogens in men are briefly discussed. The association of gynecomastia with puberty, cirrhosis of the liver, hyperthyroidism, chronic renal failure, refeeding gynecomastia, administration of digitalis and diuretics, neoplasms, and hypergonadotropic hypogonadism is reviewed. In older men, the ratio of free E2:T is increased. The relationship of andorgens, estrogens, and male sex behavior is briefly reviewed. Areas for future research include the mechanisms by which estrogens and androgens exert antagonistic effects on similar tissues, variations in the fractional conversionr ate of androgens to estrogens, the etiology of pubertal gynecomastia, the role of the free E2:T ratio in male social and sexual behavior, and the interrelation between behavior, nutrition, hormone secretion, and degenerative changes such as benign prostatic hyperplasia.

Thirty-five Black patients with cirrhosis of the liver were admitted to the professorial unit over a 1-year period and were included in a carefully planned prospective study. Men predominated over women in a ratio of 3:1. Alcohol consumption in the form of African beer was significantly higher in cirrhotic patients than in a control population. The clinical picture was neither predominantly that of alcoholic nor of cryptogenic cirrhosis. Hepatomegaly, porphyria cutanea tarda, ascites, splenomegaly and oesophageal varices were common. There was a complete absence of gynaecomastia, spider naevi and liver palms. Histologically, the majority of patients had macronodular cirrhosis, and only 1 patient had micronodular cirrhosis and minimal fatty change. Hepatitis B surface antigen (HbsAg) was not detected in any patient, despite a positive HbAg rate of 4% in Black African blood donors, determined by means of the same laboratory technique.

Oestrone (E1), oestradiol (E2), testosterone (T), androstenedione (A) and cortisol (F) as well as LH and the percentage of binding of E1, E2, T and F in plasma were measured and compared in normal young and old male subjects and in male patients with fatty liver, chronic hepatitis and cirrhosis of the liver. The alterations seen were most marked in the cirrhotic patients, but were partially also found in patients with fatty liver and in normal old subjects: a definite increase in E1, a smaller increase in E2, a decrease in T and a rise in LH. F remained unchanged. The ratios of E2/T and E1/T were higher in cirrhotic patients than in healthy young subjects. As the percentage of bound T in plasma rose, the oestrogen/androgen imbalance was greater in patients with liver disease and in old subjects than the ratio of total hormone plasma concentration indicates. The biological relevance of the extremely high E1 plasma concentrations in patients with cirrhosis of the liver is not known. It is suggested that the combination of elevated E1 and E2 and reduced T, which is strongly bound by increased sexual hormone binding globulin (SHBG) may be responsible for gynaecomastia and hypogonadism in chronic liver diseases. As similar alterations of steroid plasma concentrations and their binding to plasma proteins are found both in patients with liver disease and in old men, these changes may be caused by the same mechanism: namely an altered liver function.

Between July 1986 and April 1989, 334 hospitalized adult Ethiopian patients with chronic liver disease were studied according to a protocol to define their clinical features and to identify risk factors with the aim of preventive intervention. Of these, 14 had chronic hepatitis, 208 cirrhosis and 112 hepatocellular carcinoma (HCC). Both clinical and histological diagnostic criteria were employed. A detailed questionnaire was used to document demographic and clinical data. A common clinical presentation among patients with chronic hepatitis was darkening of the face and hands with or without hypertrichosis of the face and blisters over the dorsi of the hands. This overt or latent form of porphyrea cutanea tarda (PCT) responds to chloroquine. Patients with cirrhosis of the liver commonly present for the first time with ascites, splenomegaly, haematemesis and/or melena from oesophageal varices, and mental changes due to hepatic encephalopathy. Overt or latent forms of PCT are also common features. Peculiar to these cirrhotics is the rarity of spider naevi, gynaecomastia, testicular atrophy, Dupuytren's contracture, parotid gland enlargement and clubbing of the fingers. Exhaustion, loss of appetite, rapid loss of weight, right upper quadrant and/or epigastric pain (all often of less than 6 months' duration, a big, hard, tender and grossly nodular liver with bruit, signs of portal hypertension, and/or hepatic encephalopathy, in a young male with a rapid down hill course characterize the Ethiopian patient with HCC. Serum anti-nuclear factor, anti-mitochondrial anti-bodies and anti-smooth muscle anti-bodies were absent in those with chronic hepatitis and were uncommon in the cirrhotics and HCC cases. One or more hepatitis B virus markers were found in 86% of chronic hepatitis, 88% cirrhosis and 78% HCC and the HBsAg carrier state was found in 36%, 29% and 23%, respectively. Among the HBsAg carriers, HBeAg positivity was less common than anti-HBe but anti-HDV was significantly higher than in the healthy general population. Alphafetoprotein (AFP) levels greater than 500 mg/ml were present in 16 (8%) cirrhotics and 58 (52%) patients with HCC. Histologically, 3 of the chronic hepatitis patients had progressed to cirrhosis, 8 of the cirrhotic patients had chronic active hepatitis and 85% of HCC cases occurred in a background of macronodular cirrhosis. Three cirrhotics developed HCC during follow-up.(ABSTRACT TRUNCATED AT 400 WORDS)

Hepatocellular carcinoma (HCC) may uncommonly present with distant metastasis in the absence of a documented neoplasm in the liver. The authors herein describe the case of a 60-year-old man with cirrhosis who developed unilateral enlargement of the breast and a subareolar mass. This problem was clinically thought to represent gynecomastia, but a mammary fine-needle aspiration biopsy demonstrated a malignant epithelial neoplasm composed of large granular amphophilic cells. Bile pigment was visualized in the tumor on aspirate smears and cell block preparations; immunostains showed reactivity for cytokeratin and alpha-fetoprotein, but there was no positivity for epithelial membrane antigen, gross cystic disease fluid protein-15, vimentin, estrogen receptors, progesterone receptors, or S100 protein. These results indicated a diagnosis of metastatic HCC, which was subsequently confirmed by computed tomography of the abdomen.
