Cutaneous metastases from internal carcinornas are relatively rare. The frequency of metastases to the skin varies from 0.5-4.4%. We report a case of cutaneous metastasis suspected to originat from stomach cancer. A 44-year-old female, who had an episode of total gastrectony under diagnosis of stornach cancer three years ago, had multipe painless erythernatous nodules on the case and neck for one year. Histologic findings shows atypical anaplastic cell infiltration at the derr is and subcutaneous tissues. Cells with hyperchrornatic and erally displaced nuclei were recogniz d PAS staining shows positive reactions within the cells of glarid like structure. She died twelve month after the appearance of the cutaneous lesions.

OBJECTIVE: The purpose of this study attempts to determine the endocrinologic characteristics and changes in glucose metabolism before/during pregnancy according to different body weights in women with Polycystic ovarian syndrome (PCOS). METHODS: 94 women dia with PCOS were evaluated through measuring serum hormone levels and oral glucose tolerance tests preconceptionally and gestationally. RESULTS: In patients who were of normal weight showed significantly increased serum LH levels compared to those who were overweight (12.8+/-0.9 Vs. 7.1+/-0.8 mIU/ml, p= 0.000), and the serum levels of insulin was increased significantly in the overweight group (7.1+/-0.7 Vs. 15.2+/-2.8 ulU/ml, p= 0.000). the IGFBP-I (32.8+/-10.6 Vs. 8.3+/-2.5 ng/ml, p=0.034) and SHBG (55.8+/-4.2 Vs. 37.1+/-3.1 nmol/ml, p= 0.001) were significantly lower in the ovnweight group. The oral glucose tolerance test before/after pregnancy showed increased frequency of abnormal glucose metabolism, in both of the non-obese group (38.8%, 26,9%) and the obese group (64.2%, 53.9%) compared with normal population. CONCLUSION: It is thought that in the normal weight group with polycystic ovarian syndrome androgen production is stimulated in the theca cells by abnormally high LH secretion, while in the overweight group the hyperinsulinemia state which decreases the SHBG and IGFBP-I, lead to increase biologically active hee androgens and IGF-I and increase insulin binding to its receptor. And during/before pregnancy, women with PCOS showed that incidence of abnormal glucose metabolism was significantly increased in both of non-obese and obese groups.

BACKGROUND/AIMS: The nature of gallbladder polyp is obscure before operation, and surgical indication is still controversial. The aim of this study is to suggest the therapeutic guideline for patients with the gallbladder polyps in the laparoscopic era. METHODS: Among 49 patients who received cholecystectomy because of gallbladder polyp from January 1, 1992 to December 31, 2000 in Department of Surgery, Seoul Municipal Boramae Hospital, we studied 42 histopathologically confirmed gallbladder polyp patients retrospectively. These patients were divided into two groups as true polyp(adenoma, carcinoma) and pseudopolyp(cholesterol, inflammatory, hyperplastic), and clinical characteristics were compared between the groups. RESULTS: The mean age was 48.19+/-11.09 years and male to female ratio was 17:25 in all patients. Of 42 patients, 32 pseudopolyps(76.2%) and 10 true polyps(23.8%) were confirmed by pathologic examination. Of 32 pseudopolyps, cholesterol polyps(29cases, 90.6%) were most common type. 4 carcinomas and 6 adenomas were included in 10 true polyps. Of 6 adenomas, coexistence with dysplasia was present in two cases. 1 case of carcinoma was present as arising from underlying tubular adenoma. Compared with pseudopolyp, true polyp showed significant larger size in diameter than psedopolyp(p=0.014). Despite of these statistical difference, 44% of pseudopolyps was more than 10mm in maximum diameter. 2 cases of true polyp(20%) was less than 10mm. However all of the other clinical features such as, the patients's age, sex, symptom, presence of gallstones, and number of polypoid lesion were not significantly different between the groups. All 4 carcinoma patients received laparoscopic cholecystectomy are disease free state with mean 68.5 months follow-up period. CONCLUSION: Although true polyps showed statistically significant larger than pseudopolyps in maximum diameter, there was no clear cut point dividing the two groups. All of the other clinical characteristics could not differentiated true polyps from pseudopolyps. Because of the low morbidity of laparoscopic procedure, premalignant potential of gallbladder adenoma and the adenoma-carcinoma sequence are unquestionable, an aggressive surgical intervention should be proposed in the era of laparoscopic surgery.

BACKGROUND: Serologic markers are used to screen and diagnose the hepatitis B virus infection. In endemic area of hepatitis B, the coexistence of HBsAg and anti-HBs was frequently observed. This finding is unusual and difficult to interpret. In this study, we performed three molecular biologic assays-polymerase chain reaction (PCR), chemiluminescent molecular hybridization assay (CMHA), branched DNA (bDNA) nucleic acid hybridization assay- to detect HBV-DNA in the sera which showed both HBsAg and anti-HBs positivity. To define the patients` exact clinical conditions, we analysed the characteristics of the patients according to their diagnoses, other serologic markers and clinical findings. METHODS: HBsAg and anti-HBs were detected by EIA (Enzygnost, Behringwerke, Germany) from clinical specimens of Yonsei University College of Medicine Severance Hospital collected In the period between January 1996 and December 1996. Eighty three specimens from Severance Hospital and twenty two specimens from Health Care Center were randomly selected and were subjected to HBV PCR, HBV CMHA and HBV bDNA assay for the presence of HBV-DNA. RESULTS: The patients were arbitrarily divided into 4 groups on the basis of the optical density values of enzyme immunoassay results. Group I (high HBsAg and high antral-HBs) consisted of 6 cases; group II (high HBsAg and low anti-HBs) consisted of 70 cases, group III (low HBsAg and high anti-HBs) consisted of 1 case; group IV (low HBsAg and low antral-HBs) consisted of 6 cases. Among 83 cases, the positive rate was 51.8% (43 cases) using PCR method, 53.0% (44 cases) using CMHA, 60.2% (50 cases) using bDNA assay. HBeAg and anti-HBc IgM were helpful to predict the presence of HBV-DNA in the sera. CONCLUSIONS: More than half of the patients who showed both HBsAg and anti-HBs positivity were positive for HBV-DNA by molecular biologic methods. In contrast, no one whose serologic markers with only anti-HBc positivity with out HBsAg and anti-HBs positivity showed HBV-DNA positive in the sera from Health Care Center. Taken together, the management and follow-up of the patients of both HBsAg and anti-HBs positivity could be greatly aided by combined adoption of any one molecular biologic assay of HBY-DNA with other serologic markers such as HBeAg and anti-HBc IgM.
