It has been well known that liver cirrhosis, regardless of its etiology, is an important predisposing factor in hepatocarcinogenesis. However, the type of cirrhosis in hepatocellular carcinoma(HCC)-bearing liver varies not only by geographic areas but also with the cirteria applied for morphological classification of cirrhosis. To elucidate the relationship between the nodule size of HCC-bearing cirrhotic liver and clinicopathologic features, we measured cirrhotic nodule areas of 49 surgically resected HCC cases using image analyzer. The morphological type of cirrhosis was predominantly macronodular(49%), and followed by mixed(37%) and micronodular(14%). Seventy percent of the cases showed seropositivity for HBsAg. The average area of cirrhotic nodules was significantly larger in HBsAg-positive cases(mean: 6.14 mm2) than that of HBsAg-negative cases(mean: 2.5 mm2)(p<0.05), and their size was bigger in cases with grossly expansile pattern of HCC than those cases with infiltrative ones(p<0.05). Based on the above findings, we assume that seropositivity of HBsAg may influence on the regenerative activity of cirrhotic nodules and also subsequent increase of risk for further development of HCC. The presence of cirrhohsis and nodule size seem to be the important contributing factors to determine the growing patterns of HCC.

Hepatoid adenocarcinoma of the stomach has been designated to a primary gastric adenocarcinoma with minimum criteria of elevated serum alpha-fetoprotein and its histological resemblance to neoplastic liver cells. Of the 1,500 consecutive cases of surgically resected gastric carcinomas during a period of 4 years, we retrieved 14 cases of adenocarcinoma which met the histologic features of hepatoid growth and compared them histologically with 400 consecutive cases of non-hepatoid gastric adenocarcinomas. The patient's age ragned from 32 to 80 years(non-hepatoid group: 25 to 81 years) and their male to female ratio was 3.7 : 1(non-hepatoid group: 1.8 : 1). Grossly, five case were Borrmann type II and another five cases type III. All three cases of early gastric carcinomas were the submucosal type IIc. The remaining one was an advanced gastric carcinoma mimicking early gastric carcinoma. Microscopically, the hepatoid portions varied in growing patterns and arranged in either compact, trabecular or pseudoglandular pattern and gave an immunoreactivity to alpha-fetoprotein and alpha-1-antichymotrypsin. Regardless of the tumor stage, the hepatoid areas were located in the deeper portion of the tumor mass and grew in an expanding/nodular pattern. The associated adenocarcinomatous areas were mostly papillotubular, moderately to well differentiated, and frequently revealed clear PAS-negative cytoplasm reminiscent of the differentiated embryonal carcinoma. Tumor emboli and nodal metastasis were the frequent associations. We assume that the hepatoid adenocarcinoma may develop from gastric'adenocarcinoma through embryonal carcinomatous growth.

A 56-year-old man received subtotal gastrectomy for an early gastric carcinoma type IIa+IIc with submucosal invasion. The tumor was made up of mixed papillo-tubular adenocarcinoma and solid carcinomatous portion, the latter comprising approximately four-fifths of the total tumor mass. The solid portion was confined within the submucosa and revealed a mixture of trabecular, compact and pelioid patterns of large polyhedra cells, resembling hepatocellular carcinoma of the liver(Edmondson-Steiner grade 2). Sinusoid-like vascular stroma of classical trabecular hepatocellular carcinoma intervened the tumor cell nests but was not associated with endothelial-cell lining. Immunohistochemical stainings with alpha-fetoprotein and alpha1-antitrypsin gave a strong reactivity in those areas of hepatoid differentiation and in the adjacent minute portion of adenocarcinoma. The findings suggest that a portion of gastric carcinoma may transdifferentiate into cells with hepatoid features along the line of endodermal lineage.

The authors investigated the radioallergosorbent test (RAST) for the specific IgE and the prick test with hose dust mite in 129 patients with atopic dermatitis(AD) wit4 four or more family numbers. RAST and prick test results were described according to family background of respiratory atopy(RA) and severity of AD. The results are summarized as follows : l. A comparison between the prick test results and RAST reactions gave a concordance of 88%. The prick test was more sensitive than the RAST. 2. The level of specific IgE in patients with personal history(PH) or family history(FH) of RA was significantly increased compared to those in patients with only AD. 3. In patients without PH and FH of RA, the level of specific IgE in patients with FH of AD was significantly increased compared to those in patients without FH of AD. 4. The level of specific IgE did not reflect the severity of AD. From the above results, it could be concluded that type I allergy to house dust mite is not directly related to AD and it occurs predominantly in those patients with AD wha have a predisposition to RA.

We present four cases of herpes zoster treated successfully with vidarabine-5-monophosphate, two patients receiving chernotherapy and radiation therapy due to Hodgkins lymphoma or colon cancer, a patient combined with viral meningitis, and a patient with herpes zoster ophthalmicus. Viclarabine can be used to treat herpes zoster in immunosuppressed patients or patients with malignancy or patients with severe complications.

This study was undertaken to elucidate any quantitative abnormalities of Tlymphocyte subsets (helper/inducer T cell; T cell and suppressor/cytotoxic T cell: T cell) and IgE levels in the peripheraI blood in atopic dermatitis patients by using monoclonal antibodies and enzyme immunoassay, respectively. In addition we have tried to ascertain whether there are any correlations betveen such immuiiologic abnormalities and the severity of the disease. The results showed that there were significant decrease in the mean percentage of T Cells and increase in the mean value of T/T cell ratios in patients with atopic dermatitis. These changes seem to relate to the severity of the disease when evaluated as groups. A significant increase in the mean value of serum IgE was found in atopic dermatitis patients and the change was related to the severity of the disease. But increase of serum IgE level did not correlated closely with the T cell abnormalities in each patients.

Multiple, reticulated, dark brown colored, macules and patches suddenly developed on the fac, and neck of a 48-year-old Korean woman two days after a traffic accident. On physical examination and laboratory tests including serum melanocyte-stimulating hormone, estrogen and progesterone level, no abnormalities were found except cervical pain. Histological examination of hematoxylin-eosin stained sections revealed increased melanin pigmentation in the basal layer, but the number of melanocytes was not changed in DOPA stained section. Topical application of 2% hydroquinone and 20% azelaic acid ointments had been applied successively for two months each without any apparent improvement. Herein we present a case of reticulate hyperpigmentation on the face and neck, which is very acute and whose causative factors are not certain.
