We present a case of multiple trichoepithelioma associated with milia. A 12-year-old girl developed symmetrically distributed, numerous, skin-colored papules on her face, some of which were studded with milia-like whitish materials. Histopathological findings of these lesions revealed the typical findings of trichoepitheliomas with overlying milia in the upper dermis.

These radiologic studies were carried out on 265 cases of silicosis which were diagnosed clinically atindustrial Accident Hospital affiliated with Catholic Medical Collage, suring the period of 3 years from 1974 to1976. 265 cases of silicosis consisted of 96 cases (35%) of coal miner, 91 cases (34%) of coal choicer and 82cases (31%) of others. The average age was 42.2 years and average working period was 9.2years. Qualitative andquantitative features in the analysis of roentgen findings were based on UICC/Cincinnati and KLO classification.The qualitative features showed 26% of "p" opacity, 46% of "q" opacity 4% of "r" opacity as rounded profusion and5% of "s" opacity, 11% of "t" opacity, 2% of "u" opacity as irregular profusion of small opacities.Large opacitiesshowed 3% of group A, 2% of group B and 1% of group C. Quantitative features revealed 25% of Type 1, 54% of Type2, 16% of Type 3 and 5% of Type 4. The qualitative and quantitative features showed significant differences as ageand working period increased with age and working period. Major complications were pulmonary emphysema,tuberculosis and pleural abnormalities.

Fetal cystic hygroma is a rare congenital malformation of the lymphatic system appearing as a single or multiloculated fluid-filled cavity, most often in the neck. A case of fetal nuchal cystic hygroma was diagnosed by Ultrasonography at 22 weeks of gestation and the diagnosis was confirmed at autopsy. We present the case with a brief review of literature.

We performed an epidemiologic survey to investigate the dermatologic problems from cutting oils in metal workers. The personal questionnaires and dermatologic examinations were performed on 360 metal workers who were working at 50 metal industries. The pH meter (HANNA 8520) and the atomic absorption spectrometer(G.B.C. 902) were employed to measure the pH values of cutting oil and the concentration of heavy metals contained in cutting oil respeetively. The results were as follows : 1. The prevalence rates of the dermatologic disorders from cutting oil were 46.0% of eontact dermatitis, 10.9% of black comedone, and 7.1% of paronychia in orders. The dermatologic disorders that seemed to be not directly associsted with cutting oil were callosity(19.1%), burn by metal chips(9.8%), and mechanical injury(5.7%). 2. The localizations of the contact dermatitis and the black cemedone from cutting oil were 84% of hands, 6.6% of face, and 5% af forearms. More detailed localizations of the contact dermatitis and black comedone that developed in hand were 29.6% if finger tip, 27.6% of palm and palm finger, and 19.1% of palm finger only in orders. 3. The prevalence rates of the dermatologic disorders by the of cutting oil were 51.5% of soluble oil, 68.8% of insoluble oil, and 80.8% of mixed cutting oil which containing both soluble and insoluble oil. 4. The mean pH value of aoluble cutting oil was 8.0 and that of insoluble cutting oil was 7.0. 5. The concentrations of heavy metals contained in soluble oil were 32.2 mg/m3 of chrome, 6.42 mg/m3 of nickel, and 4.85 mg/m3 of cobalt. The concentrations of heavy metals contained in inspluble oil were 24.11 mg/m of chrome, 4.63 mg/m3 of nickel, and 2.30 mg/m3 of cobalt.

BACKGROUND: It is important to avoid the direct contact with water of detergents as possible for the treatment and prevention of hand eczema. OBJECTIVE: The purpose of this study is to evaluate the protective effect of skin protector, Marly skin on housewifes eczema, METHODS: The patients with hand eczema apply skin protector, Maly skin, four times a day on their both hands. They are evaluated with the scores of subjective symptor is(itch, dryness, smarting) and objective signs(erythema, scaling, fissures), and skin replica which are taken from the specified site are analysed by using an image analyser and, scanning electron micrascipe. RESULTS: 4 weeks after application of skin protector, there are statstically significant decrease of total clinical symptom scores. Scanning electron microscopic findings of the skin replicas show marked changes between the beginning and the end of the study. On quantive image analysis of the skin replicas, the length of fissure is a little decreased and the depth of rrows is slightly increased than before application of skin protector, but these are not statistically significant. CONCLUSION: Skin protector, Marly skin, has a protective effect on the development of hand eczema.

We report two cases of benign symmetrical lipornatosis, one associated with mild hyperthyroidism in a 57-year-old man and the other with alcoholic hepatitis in a 57-year-old man. In the histologic exsmination of the excised mass we found fibrous pseudocapsules surrounding adipose tissue in case 1, but not in case 2. Liposuction was performed in case 1 and simple excision in case 2 for treatment of tumors. The tumor masses were not recurred in clinical observation for follow-up 5 months after treatment.

Melamine-formaldehyde resin is widely used in manufactur ing plastics, tableware, t,extile and paper finishing, laminates, electrical insulations, and adhesives throughout the world, Allergic contact dermatitis to this resin has rarely been reported worldwide and has not been reported in Korean literature. We report a case of occupational allergic contact dermatitis to melamine-formaldehyde resin in a 38-year-old man. He had been working for a month in a textile factory when pruritic multiple erythematous patches and placjues developed on the face, both forearms and dorsa of the hands. In the factory melamine-forrnldehyde resin was used for crease resistant finishing. A Patch test revealed a positive reaction to rnelamine-formaldehyde resin.
