Papillary eccrine adenoma is a rare benign sweat gland neoplasm. It occurs most often as a solitary nodule in women and is located predominantly on the distal portion of the extremities. This tumor is similar to tubular apocrine adenoma in histological and clinical aspects, so distinction of these tumors is still controversial. We report a case of two papillary eccrine adenomas developed on the left popliteal and calf area of a 58-year-old-man, this is the first report of the multiple papillary eccrine adenomas in Korea.

Basal cell carcinoma is the most common malignant skin cancer in Korea. The lesions are most frequently found in the head and neck region. But penile basal cell carcinoma is very rare and there are only 29 other reported cases. We report a rare case of basal cell carcinoma of the penis in a 76-year-old man. He had a well circumscribed 1.3㎝×1.3㎝ thick scaly plaque with central ulcer in right penile root area for 4 years. The lesion was completely excised and no recurrence for four months.

We present an unusual case of molluscum contagiosum occurring in epidermal cyst on back of a 5-year-old girl. Histology showed an intradermal cyst containing lamellated horny materials and typical molluscum cclls. In Korean literature, 5 such case were reported. We report an additional case of molluscum occurring in epidermal cyst. (Korean J Dermatol 3003;41(6) : 790~792)

Background: Dermatitis occurring after ingestion of the urushiol chicken is quite common in Korea. Although many cases of the systemic contact dermatitis due to urushiol chicken have already been reported, systemic study on its epidemiology is not done yet. Objective .To elucidate the demography of the eaters of the urushiol chicken with its general understandings in society and the incidence of the resultant systemic dermatitis. Methods: By the help of the patients who developed the dermatitis, all the persons who ate it together with the patients were interviewed. Results & Conclusion : l. 171 eaters of the urushiol chicken(125 male and 46 female) were enrolled in this study(M:F= 3.1:1). The age group in 4th decade was the most common in male, the 5th decade in female. The age prevalence of the systemic contact dermatitis corresponded to the age prevalence of the eater. 2. Incidence rate of systemic contact dermatitis among the eaters was 32.2% (55/171). Incidence rate according to each age group were as follows : 0% in 2nd decade, 33.3% in the 3rd decade, 32.4% in 4th decade, 32.8% in 5th decade, 33.3% in 6th decade, 25% in the 7th decade. 3. One third (57/171) of the eaters ate the urushiol chicken to strengthen their internal organs, especially stomach, which they believed to be weak 70 persons (40.9%) ate it at home, 101 persons (59.1%) ate it at a restaurant. 4. Out of 67 persons having past history of allergic contact dermatitis to Rhus tree, 28 persons (41.8%) showed systemic contact dermatitis. Out of 104 persons without past history of allergy to Rhus, 27 persons (26.0%) showed systemic contact dermatitis. (Korean J Dermatol 2002;40(3): 253-257)

We report a case of a tick bite by Ixodes nipponensis found on the neck of a 75-year-old female. The tick was thought to be in the lesion for 10 days. Till now 31 cases of tick bites were reported in Korea including the present case. The review of the Korean cases revealed that the ratio of female/male was 1.3: 1, its age distribution was from 1st to 8th decade, sites of the invasion were trunk, head and neck, extremities, and anogenital area in order of frequency. Its prevalent season was spring and summer and the most common species(17/31) was Ixodes nipponensis. (Korean J Dermatol 2001;39(8): 891-895)

A 19 year old female patient presented with diffuse alopecia as her chief medical complaint. A clinical examination revealed hirsutism limited only to the on midline lower abdomen with e~levated DHEA-S(dehydroepiandrosterone sulfate) and total testosterone levels. Polycystic ovarian disease (PCOD) was diagnosed during the treatment with dexamethasone and spironolactone, which was effective to improve her alopecia. We believe that, with increasiny, concerns about hair conditions of teen-age girls there should be increasing chances for dermatologists to care for patients of PCOD first before other specialities in medicine (Kor J Dermatol 1996;34(6): 1021-1025)

Background : It has been known that androgenetic alopecia in both male and female is due to the role of the androgen hormone in the hair follicle, but the level of the androgen hormone in the plasma is controversial in relation with the development of the alopecia. Objective : We have tried the clarify if there is any or no difference in the plasma levels of the hormones between the normal female and the patient with alopecia, because the range of the plasma DHEA-S and total testosterone in the normal female is very wide. Methods : Plasma levels if the hormones were examined in 22 patients with female androgenetic alopecia and 20 normal females. Results : 1. In DHEA-S, 21(95.5%) aut of 22 female androgenetic alopecia patients were in the normal range while 20(100%) of the 20 normal females were all within the normal range. However the mean value of the hormone(88.89+101.41 g/dl) in the patient group was significantly higher than that(82.18+44.03 g/dl) of the normal group(p<0.05). 2. In total testosterone, 17(94.4%) out of the 18 patents were in the normal range while 20 (100%) of 20 normal females were all within the normal range. However the mean value of the hormone(0.22+0.20ng/ml) in the patient group was significantly higher than that(0.08+0.09ng/ml) of the normal group(p<0.05). 3. As for distribution of DIEA S according to the age, the value of the patient group was higher than that of the normal group in all age groups studied. In the distribution of total testosterone according to age, there was no difference between the normal and the patient in the twenties. After the twenties, the testosterone levels were higher in the patients than the normal females. Conclusion : There were significant differences in mean values of plasma DHEA-S and total testosterone between the patients and the normal females although individuals in both groups were largely wit,hin normal range of the hormones.

Malassezia intertrigo is a very rare clinical entity in which the clinical lesions occur in intertriginous areas as erythematous scaling macules and direct microscopic examinations of scales reveal only large numbers of yeast forms of Malassezia organism. A 59-year-old man, developed brown, finely scaling macular lesions on the inguinal areas. Direct microscopy and culture of the scalings taken from the lesional areas of the patient revealed only oval forms of Malassezia organism. [Kor J Med Mycol 5(1): 35-38]
