Condyloma acuminatum occurs in perianal and genital area by infection of human papillomavirus (HPV) and appeais as fairly soft verrucous papules or a cauliflower-like mass. So far 60 HPV types have been identified. Among them, condyloma acuminatum is predomi-nantly associated with HPV 16, 18 and rarely with 16, 18. HPV 16, 18 is regarded as a high-risk HPV infection because of the association of HPV 16, 18 with Bowens disease, cervical cancer, and anogenital cancer. In additioin, a significant appearance of cervical anaplastic lesions is preceded by condyloma acuminatum and a high prevalence of cervical dysplasia has been found in female consorts of men with geriital warts. Malignant transformation has been observed in rare incidences of condyloma acumina a on the external genitalia. We present a case of condylc ma acuminatum showing malignant transforrnation. The patient also has uterine cervical carcinonia. We detected HPV 16 in the lesion using polymerase chain reaction.

2.The Effects of Bleopuncture Technique in the Treatment of Warts.
Korean Journal of Dermatology 1994;32(3):446-450
BACKGROUND: The warts may promptly return despite being treated with a myriad of destructive methods. The most successful treatment has been the intralesional injection of bleomycin sulfate, but unplessant side effects caused by the difficulty of infiltrating only the wart tissue have limited its use. OBJECTIVE: Our purpose was to determine the effects of bleopunciure technique in the treatment of warts. METHODS: We performed a multiple puncture technique using a 25 gauge hypodermic needle to introduce bleomycin hydrochloricle into warts. RESULTS: This technique resulted in elimination of 91.4% of a random series on 105 warts after a single treatment. Recurrence and side effects were not observed during a 1 year follow-up period. CONCLUSION: We experienced a superior technique for introducing Heomycin into the wart, which has resulted in the cure of a signficant number of warts following a sing treatment.

BACKGROUND: The relationship and differentiation among various dendritic cells of the dermis are unclear. Recently it has hecome possible to identify different subpopulat,ions of dermal dendritic cells using anti-CD34 and anti-factor XIIIa antibodies. OBJECTIVE: To elucidate which cell types the fibrous dermal turnors consist of we compared the staining patterns of these antibodies as well as of anti-Mac 387 antibody which are labeled as inflammatory cells of the monocyte-macrophage lineage. METHODS: Tumors studied included dermatofibrosarcoma protuberans(DFSP, n=2), dermato-fibroma(n=22), neurofibroma, n=27), acrochordon(n=15), keloid, hypertrophic scar(n=10), juvenile xanthogranuloma(n=1, and malignant fibrous histiocytoma (MFH, n=1). We performed immunoperoxidase staining(AUSC technique) with polyclonal anti FXIIIa antibody, monoclonal anti-CD34 antibody, and monoclonal anti-Mac 387 antibody on the formalin-fixed-paraffin-embedded tissue specimens of these fibrous tumors. The intensity of staining was graded as negative, weakly staining, or strongly stainiring. RESULTS: FXIIIa reactivity was strongly present in dendritic and spindle-shaped cells of all dermatofibromas and some nurofibromas(11 of 27 specimens), but absent from the other fibrous tumors. Among these tumors, one of the two DFSPs was uniquely expressed CD34. Dendritic and spindle-shaped cells within tiese tumors were MAC 387 negative. In inflammatory conditions, variable numbers of MAC 38 positive cells were observed, corresponding to histiocytes and mac-rophages, but the labeling of ipithelioid cells and multinucleated foreign body giant cells were variable. CONCLUSION: The findings of significant numbers of FXIIIa positive cells in dermal fibrous tumors studied suggest that thet may be diagnostic utility associated with the use of this antit)ody. In addition, CD 34 expression by the tumor cells can be an extremely useful marker in establishing a definitive diagnosis of IFSP.

4.Immunohistochemical Study of bcl - 2 Expression in Basal Cell Carcinoma.
Korean Journal of Dermatology 1997;35(2):242-248
BACKGROUND: Basal cell carcinoma(BCC) is the most common tumor of light-skinned people. Most of them are relatively innocuous, but some may cause extensive tissue destruction, and result in death by local infiltration of vital structure or metastatic disease. The bcl-2 is a protooncogene involved in tumorigenesis by blocking apoptosis or programmed cell death. OBJECTIVE: To investigate whether there was a difference in bcl-2 expression in different histopathological types of BCC. Method: We performed immunohistochemical staining by using a monoclonal mouse anti-human bcl-2 oncoprotein in 28 BCC(nodular: 7 cases, micronodular; 3 cases, adenoid; 1 case, infiltrative; 9 cases, and mixed; 8 cases). Result: All 28 BCC expressed bcl-2, and the degree of staining was different according to histopathological types; poor prognostic micronodular(100%) and infiltrative(73.3%) types were relatively strong, and nodular(66.7% ) and adenoid(75.0%) types were moderate. Conclusion . These results suggest that the degree of bcl-2 expression in BCC seems to be dependent to the histopathological types together with clinical behavior.

Glutaraldehyde is commonly used as a biocide to disinfect delicate instruments such as dental instruments, to treat warts, hyperhidrosis and bullous diseases and as a preservative in various materials. Contact sensitivity to glutaraldehyde may not be detected, because it is not included in the standard screening chemicals recommended in the screening tests. We report a case of allergic contact dermatitis caused by Wydex(2% glutaraldehyde). A 54-year-old female made a visit to our departrnent with eczematous dermatitis of both hands, neck and face. She worked as a cleaner in delivery room and newborn nursery, and had developed the dermatitis 1 month after Wydex' containing 2% glutaraldehyde had been to clean the rooms. She had no family or personal history of atopy or contact dermatitis. Patch tests with Korean Standard(KS-1000) and Wydex were performed, and patch tests with 2% glutaraldehyde, 0.2% gluteraldehyde and rubber mix followed. The positive results were, Wydex 2% ++, 0.2% +, 0.02% + and. glutaraldehyde 2% aq. +, 0.2% aq. + on day 2 and day 4. We confirmed that the skin lesions had been caused by Wydex . The symptoms were eradicated after she changed her work environment and there has been no evidence of recurrence.

BACKGROUND: Several reports have demonstrated that TGFalpha and EGF are mitogenic for keratinocytes. Whenther its expression on epithelial tumors is a marker of malignancy or signifies an important step in the development of neoplasia is poorly understood. EGF receptors are also present in normal epidermis and epithelial tumors but their physiological roles are not yet understood. OBJECTIVE: Our purpose was to examine the staining patterns of TGFalpha, EGF and EGF receptors on the npithelial tumors of the skin, and to investigate kinetics of expression of EGF receptors. METHODS: We performed immunoperoxidase staining(ABC technique) with monoclonal anti-TGFalpha antibody, polyclonal anti-EGF antibody and polyclonal anti-EGF receptor antibody on the formalinfixed, paraffin-embedded tissue specimens of benign, premalignant and malignant skin tumors. RESULTS: The density of the expression of TGFalpha and EGF was not correlated with the degree of the malignancy of the epithelial tumors and is neither constant in any kind of the tumors. However the infiltrative type of basal cell carcinoma(BCC) is stronger that its solid type on the expression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. pression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. Focal TGFalpha immunostaining was seen in three of 10 squamous cell carcinomas(SCC) and four of 10 BCCs. TGFalpha immunostaining was absent from the outermost one to two layers of tumor lobules of all keratoacanthomas. The specimens which increased the expression of TGFalpha and EGF tended to decrease the expression of EGF receptor. CONCLUSION: These data suggest that the density of immunohistochemical expression of TGFalpha and EGF may be not dependent on the differentiation of tumor cells, and the pattern of immunohistochemical expression of TGFalpha can differentiate SCC from benign tumors such as keratoacanthoma. FGF receptor may be occupied by both of TGFalpha and EGF. With the receptors being occupied, a down regulation of the receptors may occur which results in decreased EGF receptor expression.

Previous observations have demonstrated that fibronectia (FN) is deposited high abundance in basal cell carcinoma (BCC) stroma. Since FN is a glycoprotein which promotes interaction between cells and extracellular matrix, it may been important component of slowly expansile carcinoma such as BCC. Furthermore, BCCs aggressiveness varies with it's histologic appearance. The authors investigated distribution of plasma FN (pFN) in 8 BCC cases with various histologic types (3 nodulocystic type, 2 infiltrative type, 2 keracotic type, 1 adenoid type) and 4 squamous cell carcinomas (SCC), which have a more aggrcisive biologic behavior than BCC using immunohistochemical staining. In normal skin, pFN was strongly positive at the clenzoepidermal junction and perivascular area with a linear pattern, and in the papillary dermis with a reticular pattern, and was weakly positive in the reticular dermis. In BCC, pFN was strongly positive in nodulocystic BCC, with the highest concentration along the periphery of the tumor island in a filamentous pattern, .hereas, it was moderately positive in adenoid, keratotic, infiltrative BCC stroma. In SCC, pFN was weakly positive around tumor the margins with a thin, coarse deposition These results show that with epidermal tumors, the degree of the pFN expression in stroma is propotional to their aggressiveness.
