The author observed one case of typical Linear bassal cell nevus who was 3 year old girl. Since birth, skin lesions reveal a linear band like nodules along the left lateral margin of nose, which are consists of pinhead sized, normal skin colored, pearly and translucent papules. Histopathologically, the preparations showed muItifocal irregular masses of basal type epithelial cells in continuity at pilosebaceous follicles and the cells were oval or spindle shaped and a peripheral palisade arrangement. But comedones and nevus cells were not identified. Diagnosis confirmed by clinical appearance, histopathologically and other clinical study. There were marked improvement by the locaI application of 2% 5-Fluorouracil solution.

BACKGROUND: Vitiligo is a relatively common acquired depigmentating disorder that affects at least 1 % of the population. The mode of transmission has not been clearly,stablished, but either polygenic or autosomal dominant with incomplete penetrance and variable expresion has been proposed. OBJECTIVE: Our purpose was to evaluate the causative factor, variable clinical features and current teratment of generalized vitiligo patients. METHOD: This clinical in vestigation was made with 225 outpatiens of generalized type vitiligo who had visited the Department of Dermatology, Keirnyung Universitv Hospital from January 1987 till December 1991. Results & CONCLUSION: 1. There were 125 female, (55.5%) and 100 males(44.4%). 2. The mean age of onset was 21.4 years(male . 24.3, female: 19.1). 3. The mean age at the first visit was 27.5 years (male : 28.8, female : 26.5). 4. The mean duration of the disease was 10.7 years(male : 9.9, female : 10.9). 5. The mean interval between onset and visiting was 6.1 years (male : 4.5, female : 7.4). 6. The most common sites of involvernent at the first visit was tie face 11.7% (male : 11.4%, female : 11.8%). 7. The most common precipitating factor was trauma(8.8%). 8.

Foods are recognized as a common cause of urticaria; however, the role of food is considered to be more important in acute not chronic urticaria. Wheat is a basic ingredient found in many common foods. Food allergy to wheat is primarily described in children in the form of atopic dermatitis. It is rare in adults; where it is mainly reported in exercise-induced anaphylaxis. We report a case of wheat dependent exercise-induced anaphylaxis that occurred in a 54-year-old Korean woman.

Congenital leukemia is a rare disease that develops from birth to 6 weeks of life. Leukemia cutis involves cutaneous infiltration by leukemic cells and is an unusual manifestation of leukemia, and has been documented in 25~30% of patients with congenital leukemia. The authors report a case of congenital leukemia cutis. A newborn male presented with widespread firm dusky red papules and nodules on almost his entire body surface. Skin biopsy specimens confirmed the presence of leukemic infiltrations, and bone marrow cytology was consistent with acute myeloid leukemia of the FAB M5 type.

We report here on one patient who suffered from acute myocardial infarction that was due to late stent thrombosis, and this was associated with late stent malapposition very late (21 months) after the deployment of a paclitaxel-eluting stent and shortly after (7 days) the discontinuation of the aspirin therapy. The intravascular ultrasound examination revealed that the late stent thrombosis was accompanied by late stent malapposition. This is a report on late stent thrombosis associated with late stent malapposition after the successful implantation of a paclitaxel-eluting stent (PES).

Hemophagocytic lymphohistiocytosis (HLH) is a condition caused by excessive activation and expansion of T lymphocytes and macrophagic histiocytes that exhibit hemophagocytic activity. It is a life-threatening condition, and the reported mortality rates reach 20% to 30%. It is usually associated with infection, malignancy, or autoimmune disease, but rarely with rheumatoid arthritis (RA). We recently experienced a case of HLH with rapid progression resulting in mortality in a 38-year-old female patient with long-standing RA. She visited the clinic for evaluation of a common cold-like illness. She had hypotension, liver enzyme elevation, and pancytopenia. After admission, her hypotension continued and disseminated intravascular coagulation and metabolic acidosis developed and progressed with the appearance of azotemia. Despite supportive management, she died on the fifth hospital day. HLH should be considered as a differential diagnosis when patients with RA show acute illness with fever, cytopenia, hepatic failure, and coagulopathy.

BACKGROUND:Recent studies have attempted to document the correlation of an atopy patch test (APT) and a skin prick test. The results have suggested a possible role of delayed allergic reaction in the development of eczematous skin lesions in patients with atopic dermatitis (AD) OBJECTIVE: The aim of this study was to evaluate the relationship of APT with skin prick test and specific IgE for cockroach antigen. And we attempted to find the optimal vehicle and concentration of APT for cockroach allergy in AD patient. METHODS: We performed APTs in 50 patients with AD with using German cockroach allergens (the extract with different concentrations and vehicles). The reactions were evaluated after 48 hours, and these were compared with the results of the skin prick test and the total and specific IgE levels. RESULTS: The AD patients who had cockroach allergy, according to a skin prick test or the specific IgE level, showed higher positive APT reactionsthan the non-allergic patients to cockroach. The APT reactions showed a significant relationship with the skin prick test and the specific IgE level (85.7%). With regard to the form of cockroach antigen, a positive APT was more frequent with using the powder form that with using the extract. Regarding the vehicle, petrolatum induced higher positive APT reactions than did distilled water. There was a close relationship between the antigen concentration in petrolatum base and a positive APT reaction. Ten and fifty percent cockroach antigen elicited positive APT reactions than did 1% cockroach antigen with using a petrolatum base. CONCLUSION: Petrolatum is an optimal vehicle for an APT for cockroach because an APT with a petrolatum base revealed the highest correlation with cockroach allergy. The dose-response relationship between antigen concentration and the frequencies of positive APT reactions demonstrated that 10% and 50% cockroach antigen is superior to 1% cockroach antigen.

The follicular fluid (FF) of ovary contains various biological active products which affected on the growth of follicles and the fertilization of oocyte in physiological reproductive process of mammals. This study was designed to determine the effects of human FF on fertilization of oocyte and embryonal development in vitro culture. The FF was prepared as clear without blood contamination by needle aspiration from mature follicles of human at the time of oocytes retrieval for in vitro fertilization (IVF). As the medium for culture in vitro of embryonal cells, human tubal fluid (HTF) supplemented with follicular fluids at concentrations of 10%, 40% and pure FF were used. These effects were compared to control group of cultured embryos in HTF supplemented with 0.4% BSA (bovine serum albumin). For IVF, 64 eggs in control group, 67 eggs in 10% FF, 57 eggs in 40% FF and 64 eggs in pure FF were respectively allocated. And the rates of fertilization were almost similar in all groups as resulting 82.81% in control, 85.07% in 10% FF, 87.71% in 40% FF and 81.25% in pure FF. On the examination for embryonal cleavage from fertilized eggs, the rates of developing to 4 cell stage was similar in all groups, as results 98.11% in control, 98.27% in 10% FF and 98% in 40% FF but 78.84% in pure FF. And the rates of developing to 8-16 cell stage were significantly reduced as 44% in 40% FF and 44.23% in pure FF (p<0.05) compare to 71.69% in control media. As likewise, the rates of developing to morular stage were also significantly reduced to 36% (p<0.05) and 21.15% (p<0.01) respectively in 40% FF and pure FF And the rates to blastocystic stage of embryo was lowest as 7.69% in pure FF. The quality of embryonal cells on cleavage to the 8-16 cell stage was poorer, higher concentrations of FF The rates of grade 1 in pure FF, as 23.07%, was lowest compare to those of other groups, in which the rates of grade 1 in control, 10% FF and 40% FF were 58.49%, 47.36% and 34% respectively. And on the contrary, the rate of grade 4 in pure FF was highest as 23.07%, while those were 5.66% control, 8.77% in 10% FF and 20% in 40% FF. On the viability of embryos, the rate of embryonal cell death was more rise, at the higher concentrations as well as longer exposure in the follicular fluid. At 48 hours after in vitro culture of embryos, the rate of survival embryos in pure FF was markedly lowered as 44.23%, compare to that of control (p<0.05). But there was not significant difference between the rates of survival embryos in each group beside the pure FF, which the rates were 77.35% in control, 70.17% in 10% FF and 60% in 40% FF respectively. And at 72 hours after in vitro culture, the rates of survival embryos were also significantly dropped to 21.15% in pure and 36% in 40% at concentration of FF compare to 62.26% in control (p<0.05, p<0.01). Finally, the rate of embryonal death at 96 hours after in vitro culture was highest as 82.69% in pure FF among all groups which those were 35.84 in control, 56.14% in 10% FF and 64% in 40% FF respectively. In conclusion, this study suggests that the FF has no effects, in particular, to the in vitro fertilization of oocytes but exerted a bad effect to the cleavage, quality and viability of the embryonal cells during in vitro culture. However, the FF is harmful on embryonal development at conditions in higher concentration and especially on the embryos after 8~16 cell stage.

Eccrine spiradenoma is a rare benign tumor which is differentiated into the direction of eccrine gland. Neurofibromatosis type-1 is an autosomal dominantly inherited disorder that is characterized by neurofibroma, cafe au lait spots and axillary freckles of the skin. We report a case of a 42-year-old man with a painful, solid nodule on his right arm for 4~5 months. He was diagnosed with neurofibromatosis type-1 in childhood. He has several cafe au lait spots and diffuse freckles on whole body. On microscopy, the tumor was sharply demarcated with encapsulated lobules in the dermis. The lobules consisted of two undifferentiated epithelial cells. There was hyperpigmentation of the basal cell layer in the epidermis without increase in the number of melanocyte. We herein report an unusual case of eccrine spiradenoma in neurofibromatosis type-1 patient.

BACKGROUND: Chronic irritant contact dermatitis, the common occupational dermatitis of the skin, could be caused by repetitive exposure of the skin to irritants. Adaptation of the skin to repeated influence of exogenous irritants is called the hardening. The defining characteristic of hardening phenomenon has been progressively decreasing inflammatory response with prolonged exposure to an irritant. OBJECTIVE: The purpose of this study was to evaluate the induction of hardening phenomenon by the repeated application of various concentrated sodium lauryl sulfate (SLS) solutions. METHODS: Once a day a 0.1%, 0.5%, 2% solution of SLS and distilled water were applied to the volar forearm skin in 15 healthy volunteers for 10 minutes over 3 weeks. After 3 weeks interval of rest, patch tests with 1% solution of SLS were conducted on previously irritated sites for 24 hours. We measured transepidermal water loss (TEWL) and erythema index (E-index) before irritation, during 3 weeks of repeated application. 4 days after the patches test, we measured TEWL and E-index once a day. RESULTS: During 3 weeks of irritation with repeated application of 0.1%, 0.5%, 2% SLS solution, increase of TEWL was accelerated according to concentrations of SLS. In the study of 24-h patch test with 1% SLS solution on previously irritated sites after 3 weeks interval of rest, TEWL on distilled water application site was significantly higher than other sites irritated with SLS solution on D44 and D45. The TEWL values on the site irritated with higher concentration of SLS solution were lower than those with lower concentration of SLS solution. In contrast, there were no significant differences in E-index value during 3 weeks of irritation and after 24-h patch test with 1% SLS solution. CONCLUSION: Hardening could be induced by repeated irritation with SLS solution for 3 weeks. We suggest that hardening could be induced more efficiently with the higher concentration of SLS solution than the lower concentration.
