A clinical study was made on 148 cases of cutaneous malignant tumors that visited the Department of Dermatology at Seoul National University Hospital during a 11-year period from 1973 to 1983. The results were summarized as follows: 1) The incidence of cutaneous malignant tumors in the total number of outpatients visiting the Department of Derrnatology was 0. 025g. 2) There were 90 cases of male (60. 8p,) and 58 cases of female (39. 2g). The ratio of male to female was l. 55: l. Among the 148 cases of cutaneous malignant tumors, the most frequently observed type was basal cell carcinoma, 58 cases (3j.2 p:). The next most frequent types were squamous cell carcinoma, 42 cases(28. 4g) and malignant melanoma, ]1 cases (7. 4g). We described the clinical characteristics of the patients with basal cell carcinoma, squamous cell carcinoma and malignant melanoma that have been observed.

Lupus nephropathy shows a variable clinical course including remission, relapse and progression to renal failure. To examine the clinical or morphological parameters which might be related to the progression of lupus nephropathy, we have analyzed renal biopsies of 19 patients (M : F=5 : 14), who underwent repeated renal biopsies by morphology and morphometry. The average age of the patients was 22.8+/-9.0 years. The mean interval between two biopsies was 34.5+/-13.3 months. The first renal biopsies of these patients were diagnosed with WHO class IV (74%), class II (11%), class I (5%), class III (5%), and class V (5%). According to the clinical data the patients were divided into 3 groups, static, relapsing and progressive. At the time of the first biopsies, the amount of proteinuria in both the static and relapsing groups was significantly higher than that in the progressive group (P<0.05). The volume density of the renal cortical interstitium of the first biopsies in the progressive group was significantly greater than that in the static and relapsing groups (0.14+/-0.07 micrometer3/micrometer3 vs. 0.05+/-0.02 micrometer3/micrometer3, P<0.05; 0.14+/-0.07 micrometer3/micrometer3 vs. 0.05+/-0.04 micrometer3/micrometer3, P<0.05). The activity index of the second biopsies in the relapsing group was significantly higher than that in the static group (2.7+/-0.6 vs 1.2+/-1.0, P<0.05). In the progressive group, the percentage of glomeruli with global sclerosis and the volume density of the renal cortical interstitium in the second biopsies was elevated over the first biopsies (P<0.05). Half of the patients in the static and relapsing groups underwent a morphologic transformation on the second biopsy. However, of the 7 patients in the progressive group, only one showed a transformation from WHO class IV to class III, suggesting that the transformation is not related to the progression of lupus nephropathy. These results suggest that interstitial expansion and heavy proteinuria at the time of the first renal biopsy may bode for poor prognosis in lupus nephropathy. Furthermore, they suggest that an increased histologic activity index could be related to the relapse of the disease.

We herein presented a case of persistent variant of Grovers disease in a 83-year old male. He had a rather extensive eruption of erythematous scaly papules, which had been profusely grouped but discretely distributed over 2 years or more. The histopathologic findings of two lesions in the same patient revealed mixture of various histologic patterns, patterns resembling Dariers disease, pemphigus vulgaris, Hailey-Hailey disease and spongiosis. The ultrastructural findings of Darier pattern should be essentially similar to those of Dariers disease and also be common to those observed in the early stages of other causes of focal acantholytic dyskeratosis. The patient had been treated with topical and intralesional steroid and oral 13-cis-isotretinoin, however, the lesions had been persisted only with partial improvement of clinical appearance and reduction of pruritus.

The study comprises 127 inpatients with drug eruption, treated at the Department of Dermatology, Seoul National University Hospital, during a 10-year period. The results are summarized as follows: 1. Out of 1,434 dermatologic inpatients, 127(8. 9%) patients were diagnosed as drug eruption. 2. The cutaneous manifestations of drug eruptions in the order of frequency were as follows: exanthematous eruption, urticaria, erythema multiforme, Stevens Johnson syndrome, TEN, exfoliative dermatitis, fixed drug eruption and purpura. 3. Antibiotics and antimicrobials were the most common causative agents followed by antipyretics and analgesics, CNS depressant drugs and herb drugs. 4. The 5 most common drugs causing drug eruptions were ampicillin, acetyl salicylic acid, diphenylhydantoin, sulfonamide and phenacetin.

We report a 27-year-old male with rnultiple pruritic papulovesicular eruptions on the whole body without any gluten-sensitive enteric syrnpoms. A skin biopsy specimen showed subepidermal vesicles and papillary microabscesses infiltrated with rnany neutrophils and a few lymphocytes and eosinophils. Direct immunofluorescent study of the perilesional skin revealed linear deposits of immunoglobulin A along the dermo-epidermal junction. The lesion responded rapidly to oral dapsone and topical steroid therapy.

OBJECTIVE: To evaluate whether the rate of early mouse embryonal development could be enhanced by cumulus cell coculture in vitro. METHODS: Ham's F-10 culture media supplemented with 0.4% bovine serum albumin were used. Two-cell F1 mouse embryos were cultured in media with or without cumulus cells of female ICR mouse embryo for 96 hours, and the rates of embryonal development were observed and compared. RESULTS: The percentage of hatched blastocyst in the coculture group was significantly higher than that in the control group by 87.3% vs 64.8% respectively (p< 0.05). CONCLUSION: This study provides confirmative information that cumulus cell coculture will be useful in enhancing early mouse embryonal development.

A 36-year-old female patient with sarcoidosis is presented showing lupus pernio, papular skin lesions, cervical lymph node enlargement and lung lesions. Diagnosis was confirmed by characteristic histologic findings of noncaseating granulomas in skin and cervical lymph node, supported by compatible clinical and laboratory features. Methatrexate was administered orally, which resulted in considerable improvement of skin lesions.

STUDY DESIGN: This study was undertaken to document the effect of TGF-beta 1 and TGF-beta2 on the proliferation of lumbar facet joint capsule. OBJECTIVES: To study the effect of TGF-beta1 and TGF-beta2 on the proliferation of lumbar facet joint capsule and their proliferation mechanism. SUMMARY OF LITERATURE REVIEW: TGF-beta1 and TGF-beta proliferated mesenchymal tissue . This proliferatine mechanism was involved of PLC-gamma- 1 and tyrosine kinase in signalling. MATERIAL AND METHODS: Three lumbar facet joint capsule was cultured in DMEM-20 media. Its proliferatine and inhibited effect was studied under the metabolic inhibitors and trasnsforming growth factors . RESULTS: TGF-beta1, and TGF-beta2, increased cell proliferation dependent on time and dosage. Both of TGF-beta1, and TGF-beta 2, specific antisense oligonucleotide blocked tile autoc.me effect of growth factor, PLC-gamma-1 specific antisense oligonucleotide inhibited the effect of TGF-beta 1, and TGF-beta2, Genistin inhibited the effect of TGF-beta 1, and TGF-beta2, in time and dosage dependent manner. CONCLUSION: The cell proliferation of lumbar facet joint capsule was involved in PLC- gamma-1 and tyrosine kinase in signalling.

Adenoma of the nipple is a benign tumor of the lactiferous ducts of the nipple which frequently causes erosion of the surface. It can clinically mmic Paget's disease and histologically be misdiagnosed as a well-differentiated adenocarcinoma. A 20-year-old woman developed an erythematous oozing patch on the right nipple two years ago, which subsequently developed iiito verrucous surfaccd papules. A biopsy specimen of the lesion showed focal acanthosis of the epidermis. The tumor was composed of fairly well-circumscribed, glandlike structures within the nipple stroma. Ductlike struciures, papillary areas, solid nests of cells and cysts lined by squarnous epithelium, could be seen, Two cell types lining the ducts were recognized; inner columnar cells and peripherally located cuboidal cells. Although simple excision of the adenoma is the treatment of choice, our case was treated successfully by electrucoagulation.
