1.A Clinical Observation of Cutaneous Malignant Tumors.
Korean Journal of Dermatology 1984;22(4):394-403
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.

2.Histopathologic Study of Drug - Induced Morbiliform Eruption and Erythema Multiforme.
Korean Journal of Dermatology 1987;25(4):451-459
A histopathological observation of drug-induced morbilliform eruption and erythema multiforme was made on 32 patients with drug eruption, We found that many histopathologic features of drug-induced morbilliform eruption of basal cell layer with infiltration of derrnoepidermal junction and necrosis of epidermal keratinocyte were similar to those of drug induced erythema multiforme. Therefore, it seems possible to regard the histopathologic features of druginduced morbilliform eruption and erythema multiforrne as a cornmon tissuc reaction with spectral expression.

Simple congenital lymphedema is a congenital form of chronic lymphedema of unknown etiology which affects a part or all of the one extremity, especially the lower extremities, at or immediately after birth. A clinical classification of lymphedema was offered by Allen and Ghormley in 1935, based on a study of 300 cases of lymphedema of which 12 cases are simple congenital lymphedema. They classified the cases of lymphedema into two divisions: noninflammatory and inflammatory, with a tabulation of primary and secondary causes. One caes I reporting is classified as being of congenital origin and naturally comes under the noninflammatory group. On May 1960, a 3 year old girl entered to the Department of Orthopaedic Surgery, Kyungpook National University Hospital because of lymphedema of right leg. Since at birth, there were no history of skin infection, cellulitis and lymphangitis etc. Gross appearance of the skin of the affecte leg revealed leather like consistency and thickening. One week of preoperative preparation of the patient was sustained absolute bed rest with elevation of affected limb to ease drainage of lymphatic fluid. The two staged operation of Homans procedure were performed under general anesthesia, first to medical half and second to remaining lateral half of the affected leg. The end result was relatively good in decreasing the circumfence of affected leg but it was not quite acceptable in its cosmetic effect. The literature on primary lymphedema is reviewed.

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.

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.

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.

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.

PURPOSE:The International Labor Organization (ILO) has established an international standard for chest X-ray diagnosis of pneumoconiosis since 1980. However, there is a need for improved diagnosis and staging in occupational disease. We evaluated Ga-67 citrate scintigraphy quantitatively and correlated the scintigraphic findings with pulmonary function tests and chest X-ray result. MATERIALS AND METHODS: Twenty-five patients underwent whole body scintigraphy with additional chest and abdomen images 48 hrs after intravenous injection of 185 MBq of Ga-67 citrate. Ten normal controls were also studied. Regions of interest (ROI) were drawn on the posterior image to measure counts from the liver and lungs (Lung/Liver Ratio). RESULTS: L/L ratio according to the stages of chest X-ray classification were as follows; stage 0 (normal, n=10): 0.3948+/-0.0692, stage 1 (n=10): 0.5763+/-0.1837, stage 2 (n=11): 0.6849+/-0.1459, stage 3 (n=4): 0.9913+/-0.0712. There was a significant correlation between the scintigraphic L/L ratio and the X-ray stage (r=0.618, p<0.05). However, no significant correlation between L/L ratio and pulmonary function tests were observed (p>0.05). CONCLUSION: Quantitative Ga-67 scintigraphy can be a useful method for staging of silicosis. However, it is not a method to assess pulmonary functional impairment.

Most studies of limb lengthening have concentrated on the osteotomy. In the present study, the response of soft tissue (muscle, artery, nerve) to different length, rates or rhythms of distraction have been investigated to define the nature of any damage and to see whether new muscle is created. The purposes of the this study are to evaluate the optimum condition for soft tissue during limb lengthening and to study the effect of different rates & rhythms of tibial lengthening on the soft tissue in rabbits hy observing the changes of muscle, artery and nerve. We lengthened the right tihiae of fifty-four growing New Zealand white rabbits by callotasis. The left tibiae were used as control. The rabbits were divided into three different rates & rhythms groups: Group 1 (increments of 0.5mm /day, divided 2 times/day), Group II (increments of 0.5mm/day, divided 3 times/day), Group III (increments of 10mm/day, divided 2 times/day). Each Group was subdivided into three lengthening groups: 1 ( 10% lengthening), 2 (20% lengthening), 3 (30% lengthening). At the end of lengthening, histopathologic & histomorphometric studies were done on the medial heads of gastrocnemius muscles, the posterior tibial artery and the posterior tibial nerve. In the histopathological study, these were stained by hematoxylin eosin, PAS and observed by light microscopy. Electron microscopic examination was done in all samples. In light microscopic findings, the sum of scores of the following five suhjects, each counted from 0 to 3, were analysed for individual groups between the experimental side and the control by the Mann-Whitney test and the kruskal-Wallis test. The following conclusions were made hased on the above observations; 1. There was no significant difference between groups I, II and III, but there was a significant dif-ference between the 10%, 20% and 30% lengthening groups by histopathologic study. And the predominant responses of muscle to the lengthening were atrophy and endomysial fibrosis. 2. There was no change in the proportion of the muscle fiber types by histomophomeric study. 3.ln the initial phase, the muscle adaptation to the gradual lengthening was attained by sliding in Jess than 20% distraction but finally the muscle was regenerated by new muscle formation. 4. Major soft tissue complication to the gradual lengthening was induced by muscle. But arteries & nerves were well adapted to the gradual lengthening up to 30% Iengthening.
