Nickel sensitivity is the most common cause of allergic metal dermatitides,, particularly in women. Women are uaually sensitized. by the objects wom close to the skin ('e.g. earring, necklace fasther, watch, suspenders, brassiere clips, etc.), and men are by occupational exposures (e.g. plating or printing industries, tools, etc.). Nickel dermatitis is frequently developed on the sites where seems to have been directly contact witb nickel substance, but secondary eruptions may develop on the areas where seems to have not been directly exposed to nickel, so that nickel dermatitie is sometimea misdiagnosed as atopic dermatitis, nummular eczema, stasis dermatitis, or other dermatitides. The authora prcsent two cases of nickel dermatitis confirmed by patch test with 2. 5% nickel sulfafte; first case-a 22 years old female who has erythemat,ous maculopapular patches on her ears, around neck, left wriat, elbows, and abdomen; second case tkat was previously misdiagnosed as mummular eczema-a 18 years old female who has large oozing and crusted patches on both lateral aspects of her right thigh and back, The authors reviewed the incidence of nickel sensitivity during past years in korea and the clinical aspect of distribution of nickel dermatitis.

The prevalence of dermographism in 96 patients of acute or chronic urticaria was studied using dermographic tester. The results were summarized as follows : 1. The prevalence rate of dermographism in acute or chronic urticaria was 26.0% (25/96). 2. Dermographism was more common in acute or chronic urticaria than in the general population(p<0.005). 3. There was no significant difference in the prevalence rate of dermographiam between acute and chronic urticaria. 4. The prevalence rate of dermographism was not significantly correlated with the level of serum IgE.

We observed clinical and histopathological findings of porokeratosis in 16 cases which comprised 2 linear types, 4 superficial disseminat:ed forms, 4 disseminated superficial actinic porokeratosis and 6 plaque types. From the observation, the following results were obtained. l. Clinical results 1) Eleven cases were men, 5 cases were women, and the sex ratio was 2. 2 to 1, age distribution was from 6 to 61 years (mean age: 34. 2years), and the distribution of age of onsets was from 2 to 52 years(mean age of onset' 23. lyears). 2) Four cases had family history of porokeratosis, but linear forms did not. 3) Nine cases had pruritus especially, all cases of DSAP and DSP except 1 case complained pruritus. 4) Tmo cases of DSAP had tendency of summer exacerbations. 2. Histopathological results 1) Cornoid lamellae were prominent in all cases of plaque types and linear types, and minimal in all cases of DSAP and DSP except 1 case. 2) Epidermis between the cornoid lamellae were normal or acanthotic in all cases except 1 case of plaque types and linear types, and were atrophic in 5 cases of 8 cases in DSAP and DSP.

The prevalence of dermographism in the general population of Korea was studied using a dermographic tester on 1, 074 persons(M: 489, F: 585, M/F= 1/l. 2). The result was summarized as follows: 1. The prevalence of dermographism from the pressure of 4, 800 Gm/sq. cm (pressure 2) was 6. 7%. 2. There were no significant difference in the prevalence between male(6.3%) and female(7%) (p>0. 1). 3, The peak age group of dermographism was third(9.4%), fourth and second decades in decreasing order.

We reviewed the clinical features and the skin biopsy slides of 27 patients who were diagnosed as PLEVA clinically or histapathologically in order to evaluate the clinical characteristics and the specific histopathological findings of PLEVA. The results were as follows : l. 13 of these 27 cases(48%) were confirmed as PLEVA. 2. PLEVA was more frequent in males(85% ), most of whom were young adults. 3. In most cases of PLEVA, the predilection site was on the trunk and extremities, and mild pruritus was a characteristic complaint. 4. Most cases of PLEVA were treated with tetracycline or PUVA therapy with temporary remission, but this therapy did not decrease the rate of recurrence. 5. Some histopathological findings previously described as typical in PLEVA(eg, trapped RBC in the epidermis, exocytosis of lymphocyte, dermal hernorrhage and lymphocytic perivasculitis) seemed not to be specific and were often seen in a variety of other dermatoses. 6. The histopathological findings of linear parakeratosis(85%) and dyskeratotic cells in the middle and upper epidermis(92% ) seemed to be significant findings for PLEUA. 7. The above mentioned histopat,hological findings for PLEVA were frequently found from the vesicular lesions or necrotic hemorrhagic papules.

Prurigo nodularis is a troublesome chronic dermatosis that showed unsatisfactory response to conventional therapies. Since thalidomide has been applied to the treatment of prurigo nodularis, although the action mechanism is still uncertain, many dermatologists have confirmed its effectiveness. We treated a 54-year-old male patient who had prurigo nodularis affecting the whole body for 10 years with 100 to 300mg of thalidomide daily as the sole therapy for 4 months. The skin lesions were flattened leaving postinflammatory hyperpigmentation and the pruritus also sub-sided. Two years after stopping thalidomide, no recurrence was observed.

BACKGROUND: According to the areas and people that are examined, there are many differences in the prevalence of syphilis in Korea. However, the reactive rate of the serologi test for syphilis showed an increase in the 1960s, and it has deerea@sed from the beginning of the 1970s. OBJECTIVE: Comparing the results of tke serologic test for syphilis which lotad been performed for the 5 years(1987-1991) on the physical examines and pregnant women who were considered as healthy, with the results with normal people, who were considered as healthy, which had been already reported, we tried to observe the change of reactive rate of serologic test for syphili. METHODS: The serologic test for syphilis, including serum VDRL test and serum TPHA test, were carried out on 25,254 healthy adults(20,405 were physical examineea eamined at National Medical Center and 4,849 were pregnant women delivered at National Medical Cer ter). RESULTS: The reaetive rate of serum VDRL test was 0.8% in 25,25 the althy adults(physical examinees 0.8%, pregnant women 0.7%). There were no stistically differerces between the annual incidences. 85.5% of VDRL-reactive subjects showed low VDRL titers(below 1:4) by the quantitative serum VDRL test, The biologic false positive reaction of serum VDRL test was 29(19.5%) in 149 VDRL-reactive subjects, using serum TPHA test as a standard. CONCLUSION: This study suggested thai, there was a decrease in the prevslence of syphilis in Korea.

Senile sebaceous hyperplasia refers to a benign enlargement of a normal sebaceous unit which is not uncommon in the old age group, and is characterized clinically by single or multiple small cream to yellowish round papules developed on the face, chiefly on the forehead and cheeks. A case of florid senile sebaceous hyperplasia developed in a 81-year-old man was presented. Because this disorder is one of the geriatric dermatoses and the average life span of our people is remarkably lengthened in recent years, we believe dermatologists should pay more attention to this kind of dermatosis.

A 24-year-old female who have had pseudoxanthoma elasticum for 14 years, showed brownish, umbilicated papules forming serpiginous pattern on the anterior neck, A skin biopsy specimen from the neck lesion revealed epidermal hyperplasia and perforating canal containing basophilic, necrotic materials and degenerated elastic fibers, also showed short, swollen and irregularly clumped elastic fibers in the lower dermis.

We compared the sensitivity and practicability for the direct examination of fungal hypae between the specimens treated with mixed Chlorazol black E solution and simple KOH(potassium hydroxide) solution in 118 cases of superficial myosis. The results were as follows: Higher positivity of fungal hypae in the specimens treated with mixed Chlorazol black E solution(99. 2%) than simple KOH solutiion(87. 3%.). 2, It was time-saving and easy to detect fungal hypae in the specimens treated with mixed Chlorazol black E solution than simple K(3H solution.
