N/A Nevus anemicus is a congenital anomaly characterized by pale macules of varying size and shape, and it is due to the increased sensitivity of blood vessels to catecholamines. However, the clinical features of nevus anemicus are not yet fully established. A clinical observation was made analyzing 26 cases of nevus anemicus over a 10-year period. Histopathological investigation in 6 cases, stain with Fontana-Masson in 4 cases, irradiation of ultraviolet B in 5 cases, digital infrared thermal imaging in 5 cases and color analysis using true-color imaging in 12 cases were also performed. The results were as follows : 1. The ratio of men to women was 1.2:1. The lesions were mostly(80%) present before the age of 18, but only 15% of the patients' lesions were present at birth. 2. The lesions were most frequently found on the face(33.3%) and neck(33.3%), followed by the chest(14.8%), lower extremities(7.4%) and back(7.4%). 3. Most patients(92.3%) had a single lesion. The extent of the lesions did not exceed 10% of the body surface area and the lesions did not show any progression or resolution. 4. The stainability of Fontana-Masson in nevus anemicus lesions showed no significant change compared with perilesional normal skin. 5. Irradiation of ultraviolet B ray(minimal erythemal dose to 80mJ/cm2) did not induce erythema on nevus anemicus lesions. 6. There was no significant temperature difference between nevus anemicus lesions and perilesional normal skin. 7. There was no significant correlation between chrominance and age. In conclusion, nevus anemicus in Korea shows the same incidence in both sexes, it usually arises at birth or childhood, but it may also develop later in life. Most patients show focal lesions that do not progress or resolve. (Korean J Dermatol 2000;38(4):449~456)

N/A Background:Langerhans cell histiocytosis (LCH) is a broad spectrum of clinical diseases having proliferation of Langerhans cells in common. LCH may be manifested in a variety of ways, ranging from a spontaneously regressing skin lesion to a multisystemic life-threatening disorder. Congenital self-healing reticulohistiocytosis is widely regarded as a limited form of LCH. It is present at birth or shortly thereafter and involute spontaneously. Objective:Our purpose was to investigate the relationship between clinicopathologic characteristics and prognosis of LCH in children. Methods:Six children with LCH were investigated clinically and histopathologically. Immunostains were performed with CD1a and S100 antibodies in 5 cases using paraffin-embedded sections and an electron microscopic examination was done in 1 case. Results:Among the 6 cases of LCH, 4 cases were confined to the skin, and 2 cases showed internal organ involvement. All LCH confined to the skin showed resolution of the skin lesion in 1 year, and 2 cases involving internal organ showed bad prognosis. Histopathological findings showed large histiocytes with eosinophilic cytoplasm in common. Immunohistochemical stains (5 cases) showed positive reactions with CD1a and S-100, and electron- microscopical observation in one case demonstrated laminated dense bodies. There was no significant histopathological or immunohistochemical difference between LCH confined to the skin which showed resolution of lesions and LCH involving internal organs with grave prognosis. Conclusions:Clinical types of Langerhans cell histiocytosis could not be differentiated only from (Korean J Dermatol 2000;38(2):191~197)

The purpose of this paper is providing an analysis of Korea’s carbon-neutral industry transition and solution for achieving just transition in korean labor market. By introduction of design thinking process in fair labor transition process, the government can form stakeholders’ social consensus on policy design in initial phase and strengthen receptivity on labor transition policy. Moreover, the government can find insightful ideas on fair labor transition, from social change and follow-up reaction caused by distinct characteristics of local industrial environment. By implementation of design thinking, the ideas for revitalization and prosperity of local industrial community and prosperity can be derived from ideation, prototype and test, and effectiveness of ideas is verified through design thinking process. Cooperation between stakeholders, involving design thinking, can provide novel solutions to problems in just transition, including innovative cooperation between public and private sectors.

Palmoplantar eccrine hidradenitis(PEH) is characterized by painful erythematous papules and nodules of abrupt onset on the soles and palms. The histologic hallmark is a predominant neutrophilic infiltrate surrounding the eccrine glands apparatus. We report a 40-year-old woman who had painful lesions on the palms and soles of 9 months´ duration and was otherwise healthy. The skin biopsy specimen showed a mixed infiltrate of multiple polymorphonuclear cells and lymphocytes located mainly in the eccrine sweat glands and periglandular area.
