A 26-year-old Korean woman had a 5 month history of pruritic, keratotic papules on the scalp, trunk, and pubic area, which were accompanied by diffuse hair loss from the scalp, eyebrows and pubic area. She also had flat-topped violaceous papules on the scalp and pubic area, and white lace-like striae on the oral mucous and hard palate. Histopathologic study of the progressive stages of the disease revealed dilated follicles filled with horny material, hyperkeratosis, hypergranulosis and hydropic degeneration of the basal cell layer. Throughout the entire subepidermal region, there was an intense bandlike infiltration of mononuclear cells, which were most prominent at the lower pole of the hair follicles. The late stage of the disorder showed atrophy of the epidermis and atrophy of the hair follicles with fibrotic tracts, and mild mononuclear infiltrate at the sites of the former hair follicles. This is the first recorded case, to the best of cur knowledge, in Korea.

BACKGROUND: Generally, there are few problems in the diagnosis of Paget's disease(PD) using the H&E stain. However, the differentiation of PD from the clonal type of Bowens disease and superficial spreading melanoma in situ that shows pagetoid spreading of tumor cells, may present diagnostic difficulties. In addition, the specia1 stains used for demonstrating the presenee of Pagets cells, such as PAS and mucicarmim, are non-specific and not always sensitive. So, inenunohistochemical stains with monoclonal antibodies against various antigens may be helpful for differentiating PD from ather morphologically similar skin lesions. OBJECTIVE: The purpose of this study was to investigate the diagnostic accuracy of immunohisto- chemical staining for diagnostic use in PD. METHODS: Immunohistochemical stains used in the biotin streptavidin amplificxl technique with monoclonal antibodies to several low rnolecular weight cytokeratin(CK)s, EMA and CEA, were performed on formalin-fixed, paraffin-embedded tissue. Twelve cases of PD(10 cases of extranmmmary PD and 2 cases of mammary PD), five cases of superficial spreading melanoma in situ and five cases of Bowens disease were investigated. RESULTS: The results were as follows. 1. Positive reactions with variable intensity using CK7, CKS, CK19 were seen in all cases(100%) of PD and the. staining intensity tor CK7 or CK19 was stronger than that of CKS. 2. Of the 12 cases of PD, both CK18 and CAM5.2 staining showed positivity in 11 cases(92%). 3. EMA and CEA staining showed positivity in 10(83%) and 9(75%) of 12 cases, respectively. 4. Some Pagets cells were negative for CK8, CK18 and EMA, although other positive cells were observed in the same sections. 5. All antigens were consistently negative in all cases of Bowens disease and superficial spreading melanoma in situ. CONCLUSION: The results show that moaoclonal antibodies to low molecular weight CKs are more sensitive than EMA or CEA in the demonstration of Pagets cells. Moreover, among the low molecular weight CK series, CK7 and CK19 are most useful for their high sensitivity and intensity.

Infantile myofibromatosis is an uncornmon, benign, self-limiting, localized or generalized process, probably of hamartomatous origin, which consists to a large degree of cells having the characteristics of myofibroblasts and sometimes of pericytes. Both solitary and multicentric forms occur. Most lesions are present at birth or in early infancy, and some are familial in origin. A female newborn presented with a firm, round, red colored, 3 x 3 cm sized tumor with central necrosis on the left chest. Histological examination revealed well-circumscribed nodules consisting of short bundles of plump, spindle shaped cells displaying staining characteristics intermediate between fibroblasts and smooth muscle cells. The tumor was immunoreactive for actin but did not stain for desmin. A Follow-up examination at the age of 3 months revealed a moderate degree of spontaneous regressior of the lesion.

Decreased sensitivity of N. gonorrhoeae to many existing antibiotics and the emergence and increase of penicillinase producing and of spectinomycin resistant N. gonorrhoeae necessitate intensive efforts to study on resistance. Male patients with uncomplicated gonococcal urethritis treated during the year 1990 at the VD clinic of Choong-ku Public Health Center in Seoul were included in this study. A total of 85 strains, 44 strains of non-PPNG and 41 strains of PPNG isolated from the patients were studied to evaluate their sensitivities to ampicillin, penicillin, cefoxitin, kanamycin, tetracycline, erythromycin, spectinomycin and cotrimazole. The results are summerized as follw: In non-PPNG strains, the range of MICs. MIC50 and MIC90 for both ampicillin and penicillin were 0.125-32, 2 and 16 mcg/ml respectively. For cefoxitin, they were 0.125-8, s and 16 mcg/ml respectively, and for kanamycin, 8--<64, 32 and 64 mcg/ml, respectively. For tetracycline, they were 1-64, 8 and 32 mcg/ml, while for erythromycin, 0.06-16, 2 and 8 mcg/ml respectively. For spectinomycin, they were 4--<64, 32 and 64 mcg/ml and for cotrimazole, 5--<160, 40 and 160 mcg/ml respectively. In the case of PPNG, the range of MICS, MIC50 and MIC90 for ampicillin were 8--<128, 32 and 128 mcg/ml respectively but for penicillin, 8--<128, 64 and 128 mcg/ml respectively. And for cefoxitin, they were 0.5-32, 4 and 16 mcg/ml while for kanamycin, 16--<64, 64 and >64 mcg/ml respectively. For tetracycline, the values were 2-64, 16 and 32 mcg/ml, and for erythromycin, they were 0.5-16, 4 and 8 mcg/ml respectively. for spectinomycin, they were 8--<64, 32, and 64 mcg/ml and finally for cotrimazole, 5--<160, 80 and 160 mcg/ml respectively. From these results, it is concluded that the MICs of both PPNG and non-PPNG were about 2 folds higher than the results of sensitivity tests at the same instituition in 1985. 2) The prevalence of PPNG among 35 gonorrhoeae patients who received treatment before the visit was 60% (21/35), while that among the patients without previous treatment was 40% (20/50). 3) In the cases of ampicillin, penicillin and cotrimazole, their MIC values were found to be significantly higher for the strains isolated from the patients with previous treatment history than those without previous treatment (p<0.05). 4) In non-PPNG strains, a significant positive correlation is found between the sensitivities to most pairs of ampicillin, penicillin, cefoxitin, kanamycin, tetracycline, erythromycin and spectinomycin. However this excludes some pairs such as : tetracycline-cefoxitin, erythromycin-penicillin, erythromycin-cefoxitin, spectinomycin-penicillin, and spectinomycincefoxitin (p<0.05). 5) In PPNG strains, a significant positive correlation is also found between the sensitivities to most pairs of ampicillin, penicillin, cefoxitin, tetracycline, erythromycin and spectinomycin. However, the exceptional cases include tetracycline-cefoxitin, erythromyoinpenicillin, erythromycin-cefoxitin, spectinomycin-penicillin, and spectinomycin-cefoxitin pairs. In addition, the sensitivity to kanamycin was found to be strongly correlated with that to tetracycline, erytheromycin and spectinomycin (p<0.05). Therefore it is essential for the management fo gonorrhoeae, together with a correct diagnosis, to use currently most effective treatment regimens which would also prevent the emergence of resistant strains. It is also suggested that when a treatment is failed, to use the durg which do not show correlation in sensitivities on re-treatment.

One-hundred-eleven herpes simplex viruses(HSV) were isolated from l09 patients who had visited the Department of Dermatology, Ophthalmology, and Gynecology of Hanyang University Hospital from 1986 through 1988, for suspected HSV lesions. The cultured viruses were classified into HSV-1 and HSV-2 by using direct and indirect immunofluorescent staining with monoclonal antibodies against HSV. In this study, HSV type 1 were predominantly involved in the HSV lesions above the waist of the patients(83.6%), and the infections caused by HSV type 2(I3.1 %) and bath HSV types(3.3%) were also noted. In contrast, the main organism of the HSV lesions below the waist were HSV-2(80.0%), and HSV-1(16.0% ) and both types(4.0%) were also involved in. The result suggested that the number of patients with HSV 1 genital herpes and/or with non-genital herpes by HSV-2 were apparently increasing. In conclusion, it is conceivable that the classification of HSV isolates might be useful for determining prognosis as well as performing epidemiologic studies of HSV infections.

BACKGROUND: The high level of susceptibility of patients with liver cirrhosis (LC) to septicemic infection is thought to be due to decreased reticuloendothelial function and irnpairment of several components of cell mediated and humoral immunity. It is well known that LC may cause many characteristic skin changes including jaundice, spider angioma, palmar erythema, xanthelasrna and nail changes such as clubbing and white nails. OBJECTIVE AND METHODS: During a 7 month period frorn April to October 1995, 100 patients who had been diagnosed as having LC were evaluated for the duration of their LC, the associated diseases they had apart from LC and various skin manifestations. Also, we performed the tuberculin test in 20 patients with LC and evaluated the correlation of the tuberculin test with severity of LC divided into 3 groups according to the Childs classification. RESULTS: The results are summarized as follows ; 1. The most frequent duration of LC was under 5 years (74%). 2. The most common associated disease of patients with LC was upper GI bleeding including esophageal varix (24 cases). Also, diabetes mellitus (13 cases) and hepatic coma (11 cases) were observed. 3. Jaundice (82 cases) was the most frequent skin rnanifestation of patients with LC. In addition, vascular changes (81 cases) and various nail changes (69 cases) were observed. Onychomychosis was the most common nail change of patients with LC. 4. 60% of the patients who were given the tuberculin test showed anergy, and the frequency of anergy increased in proport on to the severity of LC. However, it was not significant statistically (p> 0.05 ). CONCLUSIONS: Some of the skin manifestations help in the diagnosis of LC. Also, increased frequency of tuberculin test anergy in proportion to the severity of LC is thought to be related to decreased cell mediated immunity, although statistically it is not significant.
