A Case of Transient Neonatal Pustular Melanosis / 대한피부과학회지

A 6-day-old female infant had generalized superficial pustules which evolved into pigmented maucles, many of which had a peripheral collarvtte of scale. Histopsthologic stadies showed intracormeal aggregates of neutrophils. The appearance of the lesions and histopathologic finding fitted transient neonal pustular melanosis.

Effect of An Allergic Contact Dermatitis on the Irritant Response in Guinea Pigs / 대한피부과학회지

The effect of an allergic contact dermatitis on the irritant was studied using DNCB(2. 5% in acetone) as the sensitizing agent and sodium lauryl sulfate of various concentrations (0. 5, 1. 0, 2. 0% in Vaseline) as the irritant. Three groups of 30 albino Hartley strain female guinea pigs weighing between 350 g and 500 g were used. The results were as follows: 1. The animals which were sensitized with DNCB were shown to be significantly(p<0.05) more irritable than control animals. 2. The animals which were sensitized and challenged with DNCB were shown to be significantly(p<0. 05) more irritable than control and sensitized animals. These data suggest that allergic contact sensitivity as well as allergic contact dermatitis lower the threshold to a nonspecific irritant in guinea pigs, which may explain a mechanism of 'angry back syndrome.

A Case of Perforating Granuloma Annulare / 대한피부과학회지

We present a case of perforating granuloma annulare which appeared as multiple small papular lesions with central umbilication on the dorsum of both foot and sides of foot, The patient was a 12 year-old female child who had slightly tender lesions of one month's duration. Histologic study showed perforation of the epiderrnis and release of the abnormal necrobiotic material transepiderrnally. The epidermal perforation communicated with area of granuloma annulare in the dermis that consist of necrobiotic collagen surrounded by palisading mononucler phagocytes in the dermis. All the lesions resolved spontaneously with a slight hyperpigmentation in 4 months. She also had erythematous tender nodules, which diagnosed as erythema nodosum, on both shins. The lesions responded to potassium iodide 1.0g for 2 weeks.

A Statistical Study of Pediatric Dermatoses During Last 10 Years (1975 ~ 1984) / 대한피부과학회지

11,609 of childhood new outpatients seen in Department of Dermatology of Seoul National University Hospital from 1975 to 1984 were analyzed statistica,lly. The study results were summarized as follows: l. 11, 609 out of 48, 188 new outpatients were under 15 years old age, amounting to 24. l %. 2. The 10 most common dermatoses were atopic dermatitis, vitiligo, urticari, hemangiorna, contact dermatitis, fungal disease, molluscum contagiosum, scabies, impetigo and nevocellular neuvs. The most freguent age groups were 2 to 6 years amounting to 47 2p, af total outpatients. 4. The peak incidence occurred in August, while the lowest incidence occurred in November and October. 5. Dermatoses which showed increasing tendency were nevocellular nevus and vitiligo, those of decreasing tendency were contact dermatitis and impetigo,
