Hand dermatitis of silk industry workers had been a troublesome problern for a long time. It was said the cause was due to toxic reaction by denatured pupae and physical reaction from high water temperaturc. During Augnst and September 1973, patch test was performed with pupa and cocoon to 680 workers in 4 separate silk factories in order to persue the factors which may cause their hand dermatitis. Among 475 workers who had performed first patch test, only 12 workers in one of four factories showed positive reaction in pupa and we came to know that only that factory had used formalin in order to protect denaturation of pupae and cocoons. Second patch test with pupa and 1% formalin was repeated to 130 subjects including 6 of 12 positive cases in the first pateh test. Five Subjects shosved positive reaction in pupa, also 5 in 1% formalin and 2 of them showed positive reaction in both pupa and 1% formalin. In the second patch test, 3 of 6 who had been positive in pupa at first patch test were positive at pupa. It seemed to be that toxic or allergic theory is not enough to explain clearly the cause of hand dermatitis in silk industry workers. Further stucly is necessarv to elucidate how the silk fiber, water temperature and parasites in the pupa and cocoon contribute to the hand dermmatitis.

BACKGROUND: There are reviews with regard to the treatment of pigmented nevi present on the palms, soles, and genitalia. One advocated that pigmented nevi on thesa locations should be prophylactically removed to avoid their tuture development into malignant melanoma, while the other believes that this is not practicable. OBJECTIVE: Our purpose was to determine the incidence rates and clinical characteristics and to discuss the management of pigrnented nevi, developed on these areas of the Korean men. METHOD: We examined 1,537 Korean men, between 19 and 21 rears old, to evaluate the pigmented nevi on their palms, soles, and genitalia. RESULTS: Atleast 1 pigmented nevus appeared in 314(20.4%) men on the palms, 189(12.3%) on the soles, and 117(7.6%) on the genitalia. The sizes(mean diameter) of nevi on genitalia, soles, and palms were 4.5mm, 3.1mm, and 2.3mm respectively. The color of the nevi was darkest on the penile shaft(4.3 point) and then glans penis(3.9 points), soles(3.2 points), palms(2.5 points) in decreasing orders of the points. Most of the nevi was consistent with type 1 by Levers clinical classification and their incidence were 357 on palms, 211 on soles, and 128 on genitalia. Among the 21 nevi of type 2, 13 nevi appeared on the soles, and noine of type 3 and type 5 were found. The distribution of the nevi on the palms was of a rather uniform and scattered pattern, whereas, on the soles, they were distinctly concentrated in the midfoot. Tkie nevi on the glans penis appeared larger and more irregular in outline than those on the penile shaft. CONCLUSION: The plantar nevi were larger, darker, and had greater incidence of elevated type compared with the palmar nevi. From this observation, particular attenticn should be paid to the presence of pigmented nevi on the soles.

Microsporum gypseum, long considered to be of animal origin, has recently been found to be soil inhabitating fungus and abundant in soil throughout the world. M. Gypseum infections tend to increase nowadays in Korea. Nineteen cases of ringworm caused by M. gypseum were reported in Korean literature until 1980 to the best of our knowledge. We present 5 cases of M. gypseum infection confirmed by culture findings on Sabouraud agar media and microscopic examination. The first case was 4 year-old boy with solitary coin sinzed pruritic annular erythernatous plaque ontaining papules, pustules and scales on the right cheek of on month duration. The second case, 7 year-old boy, had solitary walnut sized ovoid plaque consisted with papulopustules, oozing and peripheral scaling on right cheek of one month duration. The third case, 5 year-old boy, had solitary egg sized pruritic erythematous plaque with papuIes, scales and crust on the right lower leg of three weeks duration. The fourth case, 63 year-old female, had solitary egg sized sharply demarcated erythematious scaly patch with central clearing on nose and. nasolabial area of 10 days duration. The last case was 2 year-old girl with solitary coin sized annular erythematous scaly pIaque on left lower leg of two weeks duration.

Thyroglossal duct cysts result from failure to obliterate the embryonic throglossal duct. When these cysts drain through the skin, they produce thyroglossal duct fistulas, which re often infected. We report two cases of thyroglossal duct fistula in an 8-year-old boaid a 41-year-old man who had a infected cystic mass and sirius on the anterior midline neck, respeticely. The cyst which is lined by a columnar epithelium was identified microscopically in a surgically n se ted specimen.

This study was designed to investigate the effects of occlusive dressing with corticosteroid on the count, size and morphology of corneocytes of normal human skin. We select 16 male volunteers, aged 23 to 25 years, without skin lesions. They were divided to 2 groups according to duration of occlusive dressing, 3 days to group 1 and 6 days to group II. Specimens were obtained from 4 sites on the back, which were studied for the effect of occlusive dressings without any topicals, with 0.l% hydrocortisone-l7-butyrate cream, with 0.25% desoxymethasone ointment, and with base of desoxymethasone, before and every 3 to 5 days after occlusive dressings, up to a total 4 times in group I and 5 times in group II.

A 3 year-old female patient was examined because of thumb-tip sized erythematous, verrucose, granulomatous mass on the nose, and coin to hen egg sized well demarked annular plaques with central atrophy and peripheral scaling, appeared on the left deltoid and clavicular area. The skin lesions showed so-called apple jelly color on diascopic examinatian. Biopsy from the lesions of nose and the left deltoid area revealed typical pictures of lupus vulgaris. Chest PA and flat abdomen revealed irregular bony destruction with reactive sclerosis involving left clavicle, 6th, 7th and 9th ribs and right 7th rib, and both iliac bones along the sacroiliac joint, and also noted unusual prominence of right paratracheal shadow. The patient was treated with isoniazid, ethambutol, rifampicin, and now is under our our observation
