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

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.

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.

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.

A 31-year-old pregnant woman with pruritus in pregnancy was described; she presented with a one-week history of generalized pruritus at gestational age 6 weeks without primary skin lesion. She had no dermatologic problem before pregnancy. Her pruritic symptom was not con-trolled with conventional emollient and topical corticosteroids. Broadband Ultraviolet B(UVB) phototherapy successfully improved her pruritus. UVB phototherapy also worked well after recurrence of pruritus at pregnancy 23rd week. We report herein a case of pruritus in pregnancy successfully treated with broadband UVB phototherapy.

Short umbilical cord syndrome, also known as the limb-body wall malformation complex and the body stalk anomaly, is a poorly defined sporadic group of congenital anomaly charaterized by a complex set of disruptive abnormalities having in common the failured closure of the ventral body wall. This disorder is charaterized by a short or absent umbilical cord and disruption of the lateral body wall, spine, limbs, face, and cranium, isolated or in combination. Recently, we present a case of short umbilical cord syndrome which found in a term baby, so we report a case of short umbilical cord syndrome with brief review of literature.

BACKGROUND: Although the main features of psoriasis consist of abnormal epidermal proliferation and T cell infiltration, which of these is the initial abnormality has been a longstanding unresolved question. Recently there has been definite evidence that activated T cells produce the cytokines that induce keratinocyte abnormalities. OBJECTIVE: We investigated the distributions and relative numbers of T lymphocyte subpopulations, that is, CD4+ and CD8+ T cells, to verify the more important T cell subtype and its infiltrating site in the formation of psoriatic lesions. METHODS: Paired psoriatic lesional and non-lesional skin tissues were obtained from eight typical psoriatic patients. Immunohistochemical staining was done on the frozen sections using a labelled streptavidin-biotin peroxidase complex method with DAKO LSAB kit. The primary antibodies used in this study were monoclonal or polyclonal antibodies against CD3, CD4, CD8, HLA-DR, and ICAM-1. RESULTS: In lesional psoriatic skin, the epidermis was mainly infiltrated by CD8+ T cells. There were little or no T cells in non-lesional epidermis. In both lesional and non-lesional dermis, CD4+ T cells were the main ones. In lesional skin, anti-ICAM-1 antibody positively stained diffusely in the endothelial cells of papillary and subpapillary plexuses and focally in epidermal keratinocytes, but in non-lesional skin only the endothelial cells in the subpapillary plexus were stained. There were many HLA-DR+T lymphocytes in lesional and non-lesional dermis. In the epidermis, HLA DR was detected only in lesional keratinocytes and T lymphocytes. CONCLUSION: These results suggest (1) participation of activated epidermal CD8+ T lymphocytes in the formation of psoriatic plaques, and (2) a pathogenetic role of ICAM-1 expression on papillary microvessels.
