1.A Case of Acquired Bilateral Nevus of Ota-like Macules.
Korean Journal of Dermatology 1985;23(4):543-546
We present a case of acquired, bilateral nevus of Ota-like macules in 50-year-old women, She had deeply brownish, confluent or solitary macules and patches distributed symmetrically on the both side of the forehead and temple, since years ago. But there was no involvement (of ocular and oral mucosa. Histopathologic findings showed flattening of the rete ridges and elongated or irregular shaped melanocytes containing many melaiiin granules, in upper-and mid-dermis. And most of melanocytes showed positive reactions on Dopa stain.

2.A Case of Scrotal Calcinosis Originated from Trichilemmal Cyst.
Korean Journal of Dermatology 1985;23(4):492-498
We experienced a case of scrotal calcinosis which was considered to be developed from the trichilemmal cysts of the scrotum. This 22 year-old male patient has been suffered from pea-sized hard muliple yellowish nodules of the scrotum since. about 5 years ago. Histopathologic findings revealed multiple cysts or calcium lumps surrounded by variable a.mounts of granulomatous inflammatory infiltrations in the dermis. The cysts were lined by stratified squamous epithelium without intercellular bridge and surrounded by scanty inflammatory cells. Several cysts contained homogenous keratinous material but most cysts contained calcium deposits within the homogenous keratinous materials or only the calcium lumps in the intact epithelial linings. Most of calcium lumps which had partially or completely disintegrated epithelial linings were surrounded by active granulomatous inflammatory infiltrations and a few calrium lumps with completely disintegrated epithelial linings had no surrounding inflammatory cells. Observing the above histopathologic features, we could consider that this case of scrotal calcinosis was developed from the scrotal trichilemmal cyst and some cases of idiopathic scrotal calcinosis, previousely reported, were the end stage of the above process.

3.A Clinical and Histopathologic Study on Skin Tuberculosis.
Korean Journal of Dermatology 1985;23(3):321-330
A clinical and histopathologic study was done on 48 cases of cutaneous tuberculosis among 43, 209 out-patients in Dermatologic department of Korea t.Jniversity Hospital during the period of 15 years and 9 mont4s from January, 1969 to September, 1984. These 48 cases were consistent with skin tuberculosis in histologic and clinicalI finc1ings, The result were summarized as follows: ]. The incidence of skin tuberculosis was 0 I 1 g among 43, 209 cases of outpatients. 2. Localized type of skin tuberculosis was 3. 2 times more frequent than disseminated type. Frequent skin tuberculosis was lupus vulgaris (57 3%), erythema induratum (12, 5%), tuberculosis verrucosa cutis(8.3%) and lupus milaris disseminatus faciei (8. 3%). 4, The ratio between male and fenmle was 1: l. 1. 5 The ages of onset were variable according to the types of skin tuberculosis. but 45 8% of all cases developed in the age group between 10 and 29 years. Seasonal incidences of skin tuberculosis were 52. 1% in spring, 85%, in winter, 18. 8% in summer, 4, 2%, in autumn. 7 In histopathologic findings, there were tubercle or tubrculoid structures in all cases and typical tubercle structures were observed in 18.8% The ratio of accordance between the histopathologic diagnosis and clinicopa thologic diagnosis was 81.3%.

Livedoid vasculitis is characterized clinically by smooth or depressed ivory-white scars surrounded by hyperpigmentation and telangiectasia with or without preceding purpuric in-filtrated papules and plaques and histologically by intravascular deposition of fibrin. Its pathophysiology is still obscure. Many treatment modalities have been used, but results are not satisfactory. Recently, there have been experiences of successful treatments with danazol, a synthetic androgen. We used danazol in three patients who presented with livedoid vasculitis and were relatively resistant to treatments with aspirin and/or pentoxifylline. After 4 to 8 weeks, there was remarkable clinical improvement in all three patients.

Tuberculosis and Respiratory Diseases 2000;48(6):898-908
BACKGROUND: Eotaxin, a CC chemokine specific for eosinophils, is implicated in the pathogenesis of asthma recruiting eosinophils into the airways. Theophylline has been used for the treatment of asthma and rece was proposed to have an anti-inflammatory action. The aim of this study is to examine whether theophylline may inhibit the eosinophilic airway inflammation by reducing the expression of eotaxin. METHODS: The expression of eotaxin mRNA was assessed by Northern analysis in A549 cells 4 h after stimulation with TNF-α or IL-1β And then, theophylline was added to A549 cells stimulated with 0.1 ng/ml IL-1β. RESULTS: Eotaxin mRNA expression rates induced by 0.1, 1, 10 ng/mL TNF-α as compared with β-action were 7%, 22%, 28%, respectively. Eotaxin mRNA expression rates induced by 0.01, 0.1, 1, 10 ng/ml IL-1β as compared with β-action, were 10%, 42%, 63%, 72%, respectively. Eotaxin mRNA expression rates after addition of 0, 0.001, 0.01, 0.1 µM dexamethasone induced by 10 ng/mL TNF-α, as compared with β-action were 27%, 18%, 8%, respectively. Eotaxin mRNA expression rates after the addition of 0.001, 0.01, 0.1 mM dexamethasone induced by 0.1 ng/mL IL-1β, as compared with β -action, were 43%, 47%, 12%, 8%, respectively. Eotaxin mRNA expression rates after the addition of 0, 0.001, 0.01, 0.1, 1, 10 mM theophylline induced by 0.1 ng/mL IL-1β, as compared with β-action, were 48%, 40%, 33%, 22%, 16%, 14%, respectively. CONCLUSION: These results suggest that theophylline may reduce eosinophil infiltration of the airway at least in part by reducing the expression of eotaxin under the conditions of these experiments.

We have experienced 2 cases of lichen planus. Case 1 was a. 76-year-old male who has suffered from discrete, scaly, round to polygonal papules on the trunk and the e:xtremiities for 3 months. The VDRL test for syphilis was reactive at a titer of 1:2 and the TPHA test was positive. The skin lesions were responded to 3 weekly injections of benzathine penicillin 2.4 million units, Case 2 was a 17-year-old male who has suffered from discrete, erythematous to violaceous colored, flat papules on the right shin for several months. He has treated with oral medication of griseofulvin. After 2 weeks of the medication, the skin ]esions showed improvement with gradual reduction of pruritus and flattening of the papules. About one month of the medication, all skin lesions cliappeared with dark brownish hue and hypopigmentation. And recurreci lesions after stopping medication are disappeared after 2 months of retreatment with griseofulvin.

Using Avidin-Biotin immunoperaxidase method, we investigate the distribution patterns of factor VIII related antigen in various areas of skin lesions of 14 granuloma pyogenicum. and in the skin lesions of 5 capillary hemangioma and 5 normal skin. The results are summarized as follows: 1. Factor VIII related antigen was detected in 9 of 14 cases of granuloma pyogenicum, in 4 of 5 cases of capillary hemangioma, and in 5 of 5 cases of normal skin. 2. In the lesions of granuloma pyogenicum the areas with prominent capillary endothelial cell proliferation had less positivity than the vascular areas. And the areas with relatively large vesels in the lesions of granuloma pyogenicum had similar positivity as capillary hemangioma. 3. The lesions of granuloma pyogenicum and capillary hemangioma had less positivity than the vessels of normal derrnis.

We report a case of primary cutaneous cryptococcosis on the left knee of a 67 year-old woman. She had a large ulcerated and indurated plaque with yellowish purulent exudates on her left knee. A histopathological examination from the lesion showed numerous encapsulated, round spores. Cultures from the lesion showed the presence of Cryptococcus neoforrnans. This may have resulted from an immunosuppressive state due to long-term use of oral corticosteroids.
