We have experienced a case of the more unusual form of supernumerary breast tissue which is characterized by the presence of aberrant gland tissue alone. The case was a 30-year-old female patient in puerperium with bilateral axillary masses of seven years duration. Gentle pressure over the right-sided one caused milk to exude from a skin pore. Histopathologic findings of the tumors revealed the lobules of the breast forming islands of glandular tissue.

The flexibility of surface layer of skin is largely dependent upon the layer's water content. This, in turn, depends primarily on the quantity of water soluble hygroscopic and surface active msterials within the straturn corneum, often known as the natural moisturizing fsctors(NMF). It consist of amino acid, lactic acid, pyrrolidone carboxylic acid and inorganic salts etc.. Some of these components are greatly influenced by hydrogen ion content and ionic form of them were found to be highly hygroscopic. In this experiment, sunburn exfoliated human stratum corneum and pig epidermis separated by 2N-NaBr were used as in vitro test. These tissues were so treated to hsve each pH value (3, 5, 7, 9) and their water holding capacity and hygroscopicity were measured by gravimetric method. The results are summarized as follows : 1, Water holding capactiy of sunburn exfoliated human skin showed significant increase at pH 5 (p<0.1), 7 (p<0.01), 9 (p<0.01) compared to pH 3, and increase in pH 7 (p<0.1), 9 (p<0.05) compared to pH 5 in lactic acid. In pig epidermis, there was significant increase at pH 5 (p<0.05), 7 (p<0.01), 9 (p<0.05) cornpared to pH 3 in lactic acid. 2. Hygroscopicity of pig epidermis showed significant increase at pH 5 (p<0.05), 7 (p<0.1), 9 (p<0.05) in lactic acid and at pH 5

Clothing dermatitis frequently goes unrecognized either becaue he clinical picture is mistaken for other disorders, such as seborrheic dermatitis, and prurius, or beacuse it is difficult to trace the causal agent. Contact dermatitis to disperse dyes, especially to azo dyes, has been well known and the most frequent sources of sensitization to dyes are dresses, stockings, and trousers made of synthetic fabrics We described a case of hat band contact dermatitis due to disperse dyes, proven by a patch test. Although chrome was not proven by the diphenylcirbizide method, many dyes known to be contact allergens were proved in different kinds of hat bands.

The clinical use of topical antimicrobial substances is common in clean wounds as well as contaminated and chronic wounds. This use is based on the observation that the reduction of superficial bacterial contamination promotes wound healing. While the antibacterial efficacy of topical antimicrobials has been well documented, their effects on living tissue and the process of wound healing remain controversial. Recently, there have been several trials to detect the toxicity of various antimicrobial materials by using cultured fibroblasts and keratinocytes. In this study the cytotoxicity of several commonly used antimicrobials and the cytotoxic concentrations of antimicrobials on cultured human keratinocytes and fibroblasts were compared using 3 different METHODS: 1) the MTT method showing the ability of the cells to clear the cytotoxic agents, 2) LDH release indicating damage of cell membrane, and 3) tritiated thymidine incorporation measuring DNA synthesis. In the MTT method all topical antimicrobials in their usual clinical concentration showed cytotoxicity on both keratinocytes and fibroblasts by suppressing cell proliferation. Keratinocytes were more sensitive to certain antibiotics. When the 50% inhibition concentration (IC50) of topical antimicrobials were compared, the cytotoxicity to keratinocyte was, in the decreasing order, chlorhexidine, hydrogen peroxide, povidone iodine, sulfadiazine, fusidic acid, ethanol. Gentamicin and bacitracin. The cytotoxicity to fibroblasts was, in decreasing order, chiorhexidine, hydrogen peroxide, povidone iodine, fusidic acid, ethanol, sulfadiazine, bacitracin, and gentamicin. Most of the antimicrobials tested increased LDH release by keratinocyte in IC50.Chlorhexidine, hydrogen peroxide and povidone iodine showed statistically significant increase in LDH release. The tritiated thymidine incorporation study showed the order of cytotoxicity to keratinocyte in IC50 of each antimicrobials was similar to that of the MTT method. Tritiated thymidined incorporation, however, appeared to be a more sensitive method in detecting cytotoxicity than MTT because the IC50 was lower in the former. In conclusion, all topical antimicrobials are cytotoxic to keratinocytes and fibroblast in their usual concentration. Because of their cytotoxicity it is suggested that one should use topical antimicrobials in a dilution of up to 1 : 1,000 of commonly used concentration for a short period only especially when applied directly on a skin graft or wounds without a protective barrier. Bacitracin or gentamicin appear to be less cytotoxic among all the antimicrobials tested.

Because most of the benign skin appendage tumors arise from pluripotential cells that form during adult life and possess the potentiality of differentiating in more than one direction, combinations of several tumor types can occur. We report a case of combined with eccrine poroma, clear cell hidradenoma, and syringocystadenoma papilliferum as a single tumor in a 41-year-old male who had suffered from a tumor on posterior neck for 5 years. The tumor was a relatively oval shaped pedunculated, and rubbery hard mass, measuring 3.5*3.0* 1.3cm in size. The outer surface was variegated and covered with hair. The diagnosis was confirmed by histopathological findings and surgical excision was done.

A case of linear IgA bullous dermatosis reported. A 32-year-old male with pruritic, papulovesicular eruptions on the whole body of 2 months' duration was examined. He had no history of diarrhea or fou]smellirig stool even though his diet cnntained gluten. A skin biopsy revealed subepidennal vesicles and papillary microabscesses infiltrated by many neutrophils and some eosinophils. Direct irnmunofluorescent examination of the perilesional skin showed a linear deposition of IgA along the basement mernbrane zone. The lesions responded rapidly to oral dapsone and topical steroid therapy but recurred whenever the oral mcdication was discontinued.

BACKGROUND/AIMS: Epidemiological data indicate that emotional stress and depression might influence the development of gastrointestianl disorders and cancers, but the relationship between the two is still unclear. The aim was to investigate the effect of stress/depression on the prevalence of digestive diseases. In addition, we tried to identify whether stress and depression are risk factors for these diseases. METHODS: A total of 23 698 subjects who underwent a medical check-up including upper and lower endoscopy were enrolled. By review -ing the subject's self-reporting questionnaire and endoscopic findings, we investigated the digestive diseases, including functional dyspepsia (FD), irritable bowel syndrome (IBS), reflux esophagitis, peptic ulcer disease, and adenoma and carcinoma of the stomach and colon. Stress and depression scores were measured by the Brief Encounter Psychosocial Instrument and Beck's Depression Inventory, respectively (Korean version). RESULTS: Stress and depression were related to FD, IBS, and reflux esophagitis. Depression was also linked to peptic ulcer disease and adenoma/carcinoma of the colon and stomach. Multivariate analysis revealed that stress and depression were independent risk factors for FD (OR, 1.713 and 1.984; P < 0.001) and IBS (OR, 1.730 and 3.508; P < 0.001). In addition, depression was an independent risk factor for gastric adenoma/carcinoma (OR, 4.543; P < 0.001). CONCLUSIONS: Stress and depression are related to various digestive diseases, and they may be predisposing factors for FD and IBS. Depression may also be a cause of gastric cancer. Psychological evaluation of gastroenterology patients may be necessary, but more study is needed.
