BACKGROUND: Molluscum contagiosum is a common viral infect oudisease of the skin and mucous membrane that is caused by a molluscum contagiosum virus(MCV; which belongs to the poxviridae family. One of the characteristic histopathologic findings is an epidermal hyperplasia Porter and Archard reported that this phenomenon might be explained by a virus induced epidermal growth factor (EGF) like polypeptide. There was a report that epidermal prolifeation in viral infection might be modulated by other factors than the virus itself such as local immune response. OBJECTIVE: The purpose of this study was to examine the expression pattern of epidermal growth factor receptor and other immunocompetent cells by immunohistochemical stainings. METHOD : We performed iinmunoperoxidase staining on the 11 slaecmens of formalin-fixed, paraffin-embedded molluscum lesions and 15 specimens of snap frozen mollucum lesions with nine primary antibodies(EGFR, factor XIIIa, CDla, S-100 protein, MAC 387, HLA-IR, CD4, CDS, L26) RESULTS: EGF receptors were strongly expressed in lesional MCV ifect,ed keratinocytes. The number of CDla and factor XIIIa positive dermal dendritic cells were sigtly increased. In inflamed lesions, CD4 and HLA-DR expressions were increased in the dermis and per lesional epidermis. CONCLUSION: This study shows that 1) increased EGFR expression is of MCV infected keratinocytes may be related to the pathogenesis of epidermal hyperplasia. 2) helper T lyrnphocytes may operate in inflamed molluscum lesions.

S-100 protein is a mixture of three proteins, that is, S-100 ao(aa), S-100 a(ab) and, S- 100 b(bb). Twenty-two case, of sweat gland tumors were stained with immunoperoxidase technique (ABC method) for the presence of S-100a and b-subunit. Four syringomas, four eccrine poromas, two eccrine porocarcinomas, two ecerine spirdeiomas, one papillary eccrine adenoma, three clear cell hidradenomas, three mixed tumr rs of the skin, two papillary syringocystadenomas, and one cylindroma were included. All specimens were formalin-fixed and paraffin-embedded. The results were as follows : 1) The staining patterns of anti-S-100a and b-protein antibodies we e simillar to those of anti-S-100 protein antibody except in eccrine poroma and porocare nomal. 2) In eccrine poroma and porocarcinoma, scattered S-100-positive dendritic cells within tumor cell nests were stained by S-100-protein antibody (3/6), but not by anti-S-100a protein antibody. S-100p is present in normal Langerhans cells. Therefore this finding suggests that these cells niay be Langerhans cells

In normal hurnan dermis, factor XIIIa positive dermal dendrocyte are located in the papillary areas closely associated with blood vessels and the upper reticular dem These cells represent a specific type of bone marrow derived dermal cells, distinct from Langerhans cells having some features in common with rnonocyte/macrophage lineage and with potential antier presenting activity. Although the significance of these cells has not yet been fully established, it been suggested that they play a major role in skin immune iesponses, in collagen synsthesis regultic and in wound repair. We report a case of acaqired fibrokeratoma which is studiec conventional histopathology and immunohistochemistry. Histopathologic findings of this case showed ovascular proliferation and the increased presence of fibroblast like cells as a common fe;ture of these benign tumors. Immunohistochemical staining with anti factor XIIIa antibody deiaoi strates increased numbera of positive dendritic cells in the upper dermis. There finding supports the fat that some fibroblagt like cells in the upper dermis of acquireid fibrokeratoma may be factor XIIIa positive dermal dendritic cells.

Neutrophilic eccrine hidradenitis(NEH) was originally described in 1982 by Harrist et al. in a patient with myelogenous leukemia receiving chemotherapy. Clinically NEH represents various cutaneous manifestations with or without tenderness and pruritus. Histologic examination demonstrates a neutrophilic infiltrate within and around the eccrine gland and degeneration of the eccrine gland structures. Although the pathogenesis and possible cause of NEH remain unknown, it is probably an unusual cutaneous reaction to chemotherapeutic agents. A few cases of infection associated eccrine hidradenitis are found in the literature. We report three cases of neutrophilic eccrine hidradenitis. Two cases were associated with hematologic malignancy. The third case was associated with an infection of Vibrio vulnificus.

Phototherapy with UVB has become a cornerstone in treating uremic pruritus. To investigate the additional benefit of emollient, we performed emollien-phototherapy in six uremic pruritus patients on hemodialysis, one of which was not responding with UVB only. After applying mineral oil over the whole body, UVB phototh.rapy was performed two to three times weekly. Improvement was noted within one to three treatments and after three to ten treatments, pruritus markedly or totally disappeared in al six patients. This result suggests that emollient-phototherapy is as effective as, or in some patients, more effective than phototherapy with UVB only in managing uemic pruritus.

BACKGROUND: A definition of granuloma is a focal chronic inflammatory response to tissue injury evolved by a poorly soluble substwice characterized by the accumulation and proliferation of the mono-nuclear histiocytic cells. The accuracy with which rnononuclear cells may be identified in skir. is much improved by the use of both heteroantisera and monoclonal antibodies directed against selected cellular antigens, OBJECTIVE: Our purpose was to examine the staining patterns of anti-lysozyme, anti-a-1-antitrypsin, anti-S-100 protein antibodies, and MAC-387 monoclonal anibody in granulomatous skin diseases. METHOD: We performed imminoperoxidase staining(the labelled str prvidin-biotin peroxidase complex method on the formalin-fixed, paraffin-embedded tissue specimens of granulomatous skin diseases. RESULTS: S-100 protein positive dendritic cells were demonstrated in the granulomatous infiltrates as scattered pattern and MAC-387 positive cells were predominantly found in the center of granulomas, The staining pattern and percentage of positively stained cells of a--antitrypsin were similar to those of lysozyme. A1Pha-1-antitrypsin and lysozyme positive cells w re present in the center as well as lymphohistiocytic infiltrates of granulomas. CONCLUSION: These data sugget that histiocytes are composed of heter igeneous groups of cells such as the mononuclear-phagocyte system and dendritic cell system.

Supernunmerary nipple is a developmental anomaly occuring alon, the course of the embryological milk lines. This entity has receieved little attention in the dermatologic literature and has been confused with a pigmented nevus in some cases. We have experienced two ease of the more unusual form of supern umerary nipple. According to the Kajavas classification, our caes are classified as polithelia pilosa and complete breast with nipple

Confluent and reticulated papillomatosis (Gougerot and Carteaud) is a rare but clinically distinct dermatosis of which the etiology is unknown. We report 2 cases. One case is a 16-year-old boy who had a hyperpigmented reticulated eruption on the trunk and both arms and the other case is a 33-year-old man who had a similar eruption on the chest and back. The former, with previous treatment with oral and topical antifungal agent in another clinic didn't show any improvement and the latter case, with initial treatment of itraconazole did not improve his skin lesion. The rashes of two patients virtually disappeared with administration of minocycline. These observations indicate that the role of microorganisms sensitive to minocycline or anti- proliferative effect of minocycline could be presumed.

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality. It is well known that androgen and sex hormone-binding globulin(SHBG) in women were associated with risk factors for cardiovascular disease such as obesity, central fat accumulation and atherogenic lipid profile. High resolution B-mode ultrasonography can visualize directly both luminal and vessel wall characteristics, and ultrasonic measurement of carotid intima-medial thickness(IMT) can be used to investigate the atherosclerosis of coronary, cerebral and peripheral arteries. The aim of this study was to evaluate the relationship between the serum dehydroepiandrosterone sulfate(DHEA-S) and SHBG, and body fat distribution pattern, cardiovascular risk factor and carotid atherosclerosis in women. METHODS: Blood pressure, fasting serum glucose, insulin, lipid profile, SHBG and DHEA-S were measured. Body fat distribution pattern was assessed by waist to hip ratio, waist to thigh ratio and subscapular to triceps skin fold thickness ratio, faf mass measured by bioelectric impedance analyzer, subcutaneous fat area, visceral fat area, and visceral to subcutaneous fat area ratio(VSR) at the level of umbilicus using the computed tomography. The IMT of the carotid artery was measured by high resolution B mode ultrasound as a marker of atherosclerosis. RESULTS: 1) There was no significant difference of age-adjusted values of carotid IMT among subjects with NGT(0.426+/-0.09mm), IGT(0.46+/-10.09mm) and NIDDM(0.453+/-0.11mm). 2) In postrnenopausal women, carotid IMT was greater(0.484+/-0.11mm, p=0.05) than premenopausal women(0.426+/-0.08mm), but it was not significant after age adjustment. Serum SHBG and DHEA-S levels in postmenopausal women were significantly lower(p<0.05) than premenopausal women, but they were not significant after age adjustment. 3) Carotid IMT was significantly correlated with age(r=0.37, p<0.01), fasting serum glucose (r=0.32, p<0.01), total cholesterol(r= 0.25, p<0.05), LDL-cholesterol(r=0.26, p<0.05), visceral fat area(r=0.35, p<0.01) and VSR(r=0.31, p<0.05). 4) By the stepwise multiple regression analysis, carotid IMT was positively and significantly associated with age(p<0.01) and serum DHEA-S concentration(p<0.05) in dent of age, body mass index, waist to hip ratio, fasting serum glucose. CONCLUSION: Carotid IMT was associated with age and serum DHEA-S concentration in women without cardiovascular disease. Therefore, serum DHEA-S may be one of risk factors for cardiovascular disease in women. However, we could not conclude its cause-result relationship because of cross sectional nature of our study, and prospective study will be needed.
