This study aimed to differentiate gastric mucosal lesions such as the inflammatory gastric mucosa, gastric dysplasia and adenocarcinoma, using the CEA(carcinoembryonic antigen), AgNORS(Nucleolar organizer regions) and PCNA(proliferating cell nuclear antigen) stains. The tissue samples were taken from 30 cases of inflammatory gastric mucosa (19 gastritis and 11 regenerative hyperplasia), 28 cases of gastric dysplasia (9 mild dysplasia, 10 moderate dysplasia and 9 severe dysplasia) and 21 cases of gastric adenocarcinoma. The CEA was expressed in 16 of 21 adenocarcinomas(76%), but in neither inflammatory nor dysplastic gastric mucosae. The mean number of AgNORs per nucleus was 1.54 in inflammatory gastric mucosa, 1.80 in gastric dysplasia, and 1.88 in adenocarcinoma. The number of AgNORs was increased in dysplasia and adenocarcinoma compared to the inflammatory gastric mucosa without statistical significance. The percentage of the PCN A positive cells was 35.2% in inflammatory gastric mucosa, 44.1 % in gastric dysplasia, and 69.0% in gastric adenocarcinoma. The positivity of the PCNA was significantly increased in adenocarcinoma compared to the inflammatory gastric mucosa and dysplasia. In conclusion, the frequency of the CEA positive staining was increased in the gastric adenocarcinoma, and so CEA stain will be able to provide an additive method for the differential diagnosis between severe dysplasia and adenocarcinoma of the stomach.

Fracture of the femur during total hip arthroplasty presents the simultaneous problems of prosthetic stability and fracture treatment. The treatment of such fractures can be complex and is one of the major challenges and this complication is associated with a high morbidity and a significant delay in convalescence. Among the 237 cases, who were treated by cementless total hip arthroplasty from Jan. 1986 to Dec. 1992, 13 cases of femoral fracture were experienced. They usually occured during insertion of prosthesis and preparation of the medullary canal. There were 6 cases of type II fracture, 1 case of type III fracture, 5 cases of type IV fracture and 1 case of type V fracture according to AAOS classification. All of the fracture healed, but the prognosis of these cases must be determined by follow up. We recommend that femoral fractures can be prevented by accurate preoperative evaluation of the size of the femoral canal, identification and management of the predisposing factors for intraoperative fractures.

The vagina is an infrequent site of primary sarcomas, which are less than 2% of all malignant vaginal neoplasm. The most common malignant mesenchymal tumor of the vagina is rhabdomyosarcoma, but leiomyosarcoma is rare type tumor of the vagina. Microscopically, spinle cells with pleomorphic nuclei and mitotic figures were frequently noted, but cross-striations were not found in the tissue. Alpha-smooth muscle actin and desmin were positive, but sarcomeric actin was negative in the tumor cells. The authors report a case of primary leiomyosarcoma of the vagina with brief literature review.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.

Linear IgA bullous dermatoses(LABD) occurring in childhood is considered to be a childhood counterpart of LABD,rather than chronic bullous dermatosis of childhood. This disease characteristically involves the perioral area,lower trunk,pelvic region and the lower extremities. Immunopathologically,it is characterized by the linear deposits of IgA at the dermoepidermal junction of the perilesional skin. A 20-month-old female infant presented with multiple pruritic tense bullae on the face, lower trunk, both extremities and pelvic region of 2 weeks duration. She had no oral lesions or any specific signs or symptoms referable to the disease of the gastrointestinal tract. A skin biopsy revealed subepidermal blisters infiltrated with many neutrophils and a few eosinophils. Direct immunofluorescence demonstrated linear deposition of IgA at the dermoepidermal junction. An indirect immunofluorescence study using NaC1-split skin as the substrate revealed fluorescence for IgA in a linear pattern on the roof of the split at a titer of 1:40. The clinical diagnosis of LABD of childhood was confirmed and we started with a combined remedy of dapsone and corticosteroids; 10 weeks later almost all of the lesions had disappeared.

This study was designed to answer the question; (1) How does the DNA ploidy pattern change in hepatocarcinogenesis? (2) How does the nuclear morphology change in hepatocarcinogenesis? Diethylnitrosamine(DEN) (16.5 mg per kg) was subcutaneously injected to female Sprague-Dawley rats(150~200g) by weekly interval for 30 weeks. DNA ploidy and parameters of nuclear morphology were measured by image analyser(IBAS 200, Kontron, FRG). The DNA ploidy pattern was divided into three basic patterns(diploid, polyploid, and aneuploid modes). In 8 cases of saline-injected control rats, the DNA histograms showed all polyploid pattern. Inhepatocyte nodules(hyperplastic nodules), DNA diploidy was the most frequent pattern, being followed by polyploid and aneuploid DNA patterns, contrast to hepatocelular carcinomas in which polyploid DNA pattern was most frequently noted being followed by diploid and aneuploid DNA pattern. Although the nuclei of hepatocytes in hepatocyte nodules and hepatocellular carcinomas were larger and more pleomorphic than those of normal hepatocytes, they were as same as those of normal hepatocytes in regard to nuclear hyperchromasia. DNA content, which was increased in hepatocarcinogenesis, was significantly related to the nuclear area.

Epstein-Barr virus (EBV) has been known to be associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, Hodgkin's disease, and non-Hodgkin's lymphoma. Recent studies reveal the presence of EBV in certain subtypes of gastric carcinoma in which EBV appears to be pathogenetically related. To evaluate the relationship between EBV and gastric adenocarcinoma, we examined EBV DNA using direct in situ polymerase chain reaction, and expression of p53 protein and bcl-2 protein using immunohistochemical staining method on paraffin embedded tissues. The materials consisted of one hundred twenty-eight gastric adenocarcinomas and twenty benign peptic ulcers. EBV DNA was detected in 14 of 128 gastric adenocarcinomas (10.9%). p53 protein was positive in 10 of 14 EBV positive adenocarcinomas (71.4%) and in 61 of 114 EBV negative adenocarcinomas (53.5%). Bcl-2 protein was positive in 2 of 14 EBV positive adenocarcinomas (14.3%) and in 19 of 114 EBV negative adenocarcinomas (16.7%). The above results indicate that EBV is associated with gastric adenocarcinoma, and p53 protein may play a role in carcinogenesis of EBV in gastric adenocarcinoma.

Pigmented photoallergic contact dermatitis is a disease usually resulting from recurrent cutaneous exposure to cosmetic photoallergens which produce bizarre dark brown hyperpigmentation. Histologicnl examination of this condition reveals liquefaction of the basal cells of the epidmis and melanophages in the upper dermis. A 50-year-female developed dark brownish mottled hyperpigmented patches on her face after using a soap named O.E. and taking a nap every afternoon for 4 years. The histological fmding on the lesion site was consistent with pigmented photoallergic contact dermatitis. The cosmetic photopatch test with, O.E. soap, and the Scandinavian scries resulted in a positive reaction only on one side where 5 J/cm2 lights were applied by using Waldman 800UV machine. The other side howed a negative finding. We fmally diagnosed pigmented photoallergic contact dermatitis based on the patients histoty of using the soap containing musk ambrette, a histological examination of a biopsy and the results of photopatch tests. We report rare case of pigmented photoallergic contact dermatitis.

Massive ovarian deema is a tate conditian. It is a benign enlargement of the ovary caused by accumulation of fluid, which is thought to result from intermittent partial toraion of the ovarian pedicle. Histologically, the ovaries were characterized by diffuse edema of medulla and inner cortex. Two cases of massive ovanan edema are reported with brief review of the literatures.
