Primary Cutaneous B Cell Lymphoma

A 7-year-old girl had a 7 × 6cm sized dark red colored tumor on the left elbow and several erythematous macules on the face, right upper arm, and both thighs. Her general health was good and all laboratory findings were within normal limit. Histopathologic examination revealed an infiltration of atypical mononuclear cells in the dermis and subcutis. L26 and leukocyte common antigen were positively stained in an immunohistochemical study. According to clinical, histological and immunohistochemical findings, we diagnosed the disease as primary cutaneous B cell lymphoma. The patient's skin lesions markedly improved after a surgical excision and chemotherapy.

A Case of Chronic Mucocutaneous Candidiasis

A 6-year-old male patient had been suffering from angular cheilitis and paronychia with fragmentation and dystrophic change of the finger nails. Laboratory findings showed low serum iron level and anemia. Immunologic studies revealed defects in cell mediated immunity. KOH examination and culture of specimens from the lesions showed hyphal elements and growth of Candida albicans respectively. Concomitantly itraconazole and iron sulfate were administered. Four months after treatment he was free of any clinical evidence of the disease.

Prevalence of PPNG in Seoul ( 1993 ) / 대한피부과학회지

BACKGROUND: In recent years gonorrhea has been panendemic and remains one of the most common STDs in the world, especially in developing countries. OBJECTIVE & METHOD: For the detection of a more effective teripeutic regimen and assessing the prevalence of PPNG, will have been trying to study the paieits who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. RESULTS: In 1993, 187 strains of N. gonorrhoeae were isolated, ar, ong which 139(74.3%) were PPNG. CONCLUSION: Our results suggests that the prevalence of PPNG in Seoul is still increasing.

Immunohistochemical Study on Proliferating Cells in Alopecia using Proliferating Cell Nuclear Antigen / 대한피부과학회지

Backgroud : The number of proliferating cell populations in the hair is follicles is closely related to the regulation of hair growth. Destruction of hair germ cells and the loss of proliferating cells have been suggested to be of major pathogenetic significance in alopecia areata OBJECTIVE: The purpose of this study is to compare the growth frrections in proliferating cells of normal hair follicles with those in alopecia. METHODS: An immunohiatochemical study was done to detect the proliferating cells in hair follicles using a monoclonal antibody against proliferating cell nuclear antigen(PCNA) in the scalp biopsy of an alopecia patient on the peraffin embedded sections. RESULTS: A significant decrease of the labelling indeces of PCNA were observed in the hair follicles of alopecia compared with normal condition. But we could not find significant differences of labelling index in the clinical types of alopecia, responses to treatment, anc systemic immunologic state. CONCLUSIONS : Whole the above results confirmed that significant decreases of proliferating cells in the hair follicle could explain the part of the pathogenetic mechanism in alopecia, its direct cause which inhibit the proliferation of cells is not clear.

Four cases of trichotillomania / 대한피부과학회지

Trichotillomania is the cllinical syndrome of alopecia resulting from the repetative pulling, plueking and breaking of ones own hair. We report four cases of trichotillomania in 10 year old children. The lesions were limited to the scalp. All of them had psychiatric problems in the school or home according to a psychiatric consultation. The histopathologic examinatiorii revealed a normal number of hair follices, empty hair follicles and no inflammatory reaction. The treatment led to hair growth in three cases but one case did not respond to the treatment.

A clinical and mycological study of superficial fungal diseases(vii) / 대한피부과학회지

BACKGROUND: Superficial fungal infections are common diseases acid the prevalence of superficial fungal diseases are not static but change under the influence of various forces such as climate, migration of peoples and development in prophylaxis and therapy. OBJECTIVE: To investigate the present status of superficial dermatiphytoses and some changes on the frequency of the diseases, sex distributions and varieties of the casiative organisms. MEHTODS: The clinical and rnycological aspects of superficial fungal diseases of 3,222 patients from July 1989 to June 1992 were analyzed. Results : 1) The incidence of superficial fungal diseases was 25.4% of total out-patients. 2) The superficial fungal diseases showed a higt incidence in the third(26.4%) and the fourth decade(24.3%). 3) The ratio of male to female was 2.11:1(2,188:1,034). 4) The monthly prevalence of super ficial fungal diseases was high inhuly(17.8%), August(15.2%) and June(1.7%). 5) The incidence of superficial fungal diseases in order of frequency were tinea pedis ,28.1%, tinea cruris(19.5%), onychomycosis(15.6%), tinen orporis(11.5%), tinea manus(7.8%), tinea versicolar(7.8%), candidiasis(7.4%) and tinea capitis(2.3%), 6) Coexisting fungal infections were found in 644 patients(19.9%) and the case of tinea pedis with onychomycosis was the most common. 7) The positive rate of KOH scraping was 54.0% and the positive rate of culture on ordinary Salourauds dextrose agar media was 42.7%. 8) Trichophyton rubr,im was the most common causative orantism of superficial dermatophytes(38.4%), and other in decreasing frequency were Candida albicans(36.9%), Trichophyton mentagrophytes(23.6%) Microsporum canis(0.7%), Trichophyton ferrvgiteum(0.3%) and Epidermophyton floccosum(0.1%). CONCLUSION: These results are not significantly different from those iif previous studies. But the incidence rate of the superficial pungal diseases(25.4%) were higher thar, previous studies and showed a high incidence in young male patients and in the summer. The positiv rate of KOH scraping(54.0%) was lower than previous studies. The most common causative organism was Trichophyton rubrum(38.4 %).
