Incontinentia pigmenti is an uncommon neurocutaneous genodermatosis characterized by three stages; vesicular lesions, verrucous lesions and hyperpigmentation. A two-week-old female infant showed grouped erythema-based vesiculopustules on the whole body since birth. One month later, vesiculopustular lesions began to disappear gradually. At this time, she developed linear verrucous plaques on the dorsum of the feet and hands and reticulated hyperpigmented patches on the lower extremities. At 2 months of age, vesicular lesions completely disappeared and the pigmented patches spread to the abdomen which became darker with time. The verrucous lesions diminished at 3 months of age. There were no neurological or ocular defects. We describe a case of incontinentia pigmenti with typical clinical and pathological features at each stage.

We rep a case of vulvar syringoma in a 32-year-old woman who had pruritus vulvae for 2 years. An examination of both the labia major revealed slightly thickened hyperpigmented or hypopigmented patches without yellow papules. A skin punch biopsy revealed characteristic histological findings of syringoma. Syringoma of the vulva is a rare disorder and is usually asymptomatic. Five cases of vulvar syringoma preriously reported in the Korean literature all had asymptomatic yellow or brown colored papules, but this case presented here was clinically considered as pruritus vulvae.

Although basic mechanisms of atopic dermatitis remain largely speculative, many studies on pathogenesis suggest the importance of food and inhalent allergens. To evaluate the frequency of food and house dust mite hypersensitivity and differences in this frequency according to ages, we measured the levels of specific IgE antibodies to egg white, egg yolk, milk, soy, and house dust mites in 119 children with atopic dermatitis. The results showed that 53% of patients had positive RAST to any one kind of allergens. The frequency of food and house dust mite hypersensitivity were 34.5%, 30.3 %, respectively. Among allergens, house dust mites and egg white are the most prevalent allergens in all atopic dermatitis patients. The Prevalence of egg white is most common under the age of 2 years, but those of house dust mites are the dust mites are the highest in the ages of 5-12 years. In conclusion, we recommend an egg restriction diet in atopic dermatitis patients who are less than 2 years old when their symptoms do not improve with general skin care.

To characterize the immunopathologic phenotype of the cells in the lesional ti.:sue and to further examine the mechanism of the development of the annular lesions in leprosy, we have studied immune cells (T lymphocyte and its subsets, Langerhans cells, and HLA-DR antigen expressing cells) at different anatomical sites inside, active border, and outside normal skin in the annular lesions of leprosy. We took biopsy specimens from 4 patients of BT type, then processed the specimens by the staining methods eif indirect immunoperoxidase with monoclonal antibodies. In the active border the number of T cell was over 50g of the total cells infiltrated in the dermis. Helper T cells were dominant in number, and about three fourths of the cells were positive for HLA-DR staining. In two patients they had expression of DR antigen on the surfaces of the keratinocytes in the epidermis, in contrast to that of the inside, even the intensities were not. strong. At the inside of the annular lesions T cells were about 40% and the ratio of helper/suppressor T cell was approxiinately 1: 1, However, HLA-DR positive immune cells were not more than 10g among the total infiltrates. Langerha,ns cells were increased in number and in size either in the border or at the inside of the annular lesions. With these results we presume that the T cell mediated imrnune responses against Mycobacterium leprae may play an important role in the formation and extension of the annular lesions in leprosy.

BACKGROUND: There is a long-standing controversy whether melanocytes in vitiligo of more than 1 year duration are actually lost or still present. Resolving this matter is essential in understanding the underlying pathology and for the development of the treatment. On previous immunohistochemical and ultrastructural studies of vitiligo lesions, damage of melanocyte and keratinocyte in early lesions were reported and complete absence of melanocyte in long standing lesions were known. OBJECTIVE: This study aimed to determine the existence of the differences in pathologic changes in melanocytes according to the duration of the lesion. METHODS: We investigated the vitiliginous skin samples from 31 patients with early(less than 1 year duration) vitiligo and 30 patients with long standing(l to 5 years duration) vitiligo under the electron microscopy. RESULTS: Multiple degenerative changes in melanocytes were observed in the early and long standing lesions. In long standing lesions, degeneration of melanocytes including pyknotic, in-dented nuclei, vacuolated cytoplasms and blunted dendrites were more pronounced than early lesions. Even in long standing lesions, definite or presumptive melanocytes were observed in 16(53.3%) of 30 cases. CONCLUSION: Our results suggest that the melanocytes of vitiligo lesions were damaged and that the percentage of degenerative changes increase in accordance with the duration of the lesion. However, in long standing lesions as well as in early lesions, some residual melanocytes can be observed ultrastructurally.

OBJECT: Pre-ALL is a very rare preteukemic state, which percedes acute lymphocytic leukemia, while MDS(pre-ANLL), usually the well-known type of preleukemic state, precedes acute non-lymphocytic leukemia. Initially it shows transient pancytopenia without any evidence of leukemia in bone marrow findings, followed by acute lymphocytic leukemia after recovery from pancytopenia of a short period within weeks or months. We report a case with pre-ALL in childhood. CASE: A 15-month-old male baby was admitted with the complaints of fever and cough for 5 days and pallor for 2 weeks prior to admission. On admission, CBC showed pancytopenia without any evidence of leukemia, which was recovered spontaneously in a short period, and then was followed by acute lymphocytic leukemia of CALLA negative, early pre-B cell type. During antileukemic chemotherapy, he had suffered from severe bacterial infections and was finally died of sepsis 8 months after first admission. CONCLUSION: We report a case of pre-ALL in childhood, which was preceded by CALLA negative, early pre-B cell ALL, with a review of the literatures, briefly.
