ABSTRACT
BACKGROUND: Dermatological diseases can occur with atopic dermatitis. OBJECTIVE: The purpose of this study was to analyze diseases associated with atopic dermatitis in Koreans. METHODS: From November, 2007, to May, 2008, 948 patients with atopic dermatitis who visited the department of dermatology at 19 hospitals were evaluated for associated diseases. RESULTS: Of 948 patients, 53.8% (510) had symptoms associated with other dermatological diseases. In order of frequency, diseases associated with atopic dermatitis included acne, hand/foot eczema, seborrheic dermatitis, urticaria, warts, and recurrent herpes simplex. The number of associated diseases did not change significantly with the severity of atopic dermatitis. However, the incidence of hand/foot eczema and eczema herpeticum correlated significantly with the severity of atopic dermatitis. CONCLUSION: There is a distinct pattern of diseases associated with atopic dermatitis in Koreans.

A 45-year-old female noticed a pruritic erythematous firm pea sized nodule on the left earlobe about 18 years prior to uisiting our clinic. The lesion has increased in size gradually and involved the whole earlobe. On March 1988, the earlobe became enlarged with extreme pruritus, and showed a tendency of easy bleeding by scratch. The skin lesions consisted of multiple pea to bean sized, shiny dusky red colored, moderate firm nodules or tumors with edema on the left. ear helix, antehelix, external auditoy meatus, and retroauricular fold. The histopathologic studies revealed vascular proliferation, presence of histiocyt.oid endothelial cells, and prominent inflammatory infiltration including large numtaer of eosinophils with fibrosis in the dermis. Hematological studies revealed eosinophilia(9%). Excision of several nodules and intralesional injection of trinmcinolon acetonide did not show complete favorable effect and treatment with carbon dioxide laser was attempted. With the patient under local anesthesia with 2% lidocaine, the lesion were treated with three t,o four passes at 25,100 second intervals with ieradiance 5W(cm. The pro- cedure was repeated until no abnormal findings could be seen in the treatment zone. Treatment with carbon dioxide Iaser on the patient obtained a satisfactory result.

This study was undertaken to know whether the UV-irradiation of the skin causes changes in the superoxide dismutase(SOD) activities. After shaving, the back skin of the rabbit was irradiated with UV light ranging from 280 to 320 nm of wavelengths from Burdick lamb (UV800) in doses of either 0.5, 1.0 or l.5 J/cm2. The skin was removed imrnediately after irradiation and the enzyme activity was assayed by the method of McCord ad Fridovich (xanthine-xanthie oxidase system), One unit of the SOD activity was defined as the amount of the enzyme required to inhibit the rate of reduction of cytochrome c by 50%. The protein content of the enzyme was determined by biuret method. The SOD activity of the skin irradiated with 1.0 J/cm was 7. 78 + 1.62 unit/mg protein(Mean+SD; n=10), significantly higher than that of the control(nonirradiated) group(5.62+1.57 unit/mg protein; n=l0). No significant changes were found in the skins irradiated with 1.5 and 1.5 J/cm. This finding indicates that UV irradiation is capablc of increasing the SOD activitiea in the rabbit skin, and suggests that increased superoxide formed by UV irradiatiun induces the increased SOD activies.

The present study was designed to measure the activity of purine nucleoside phosphorylalse (PNPase) in sera, erythrocytes and lymphocytes of blood from patients with various dermatoses as it's activities are known to be decreased in cell-mediated immune deficiency diseases. The PNPase activities in sera, erythrocytes and lymphocytes of normal subjects were (3. 9+1. 03) x 104 unit/L, 5.04+1. 06 unit/107rbc, l. 74+0. 35 unit/103 lymphocytes respectively. In urticaria, leukocytoclastic vasculitis and purpura, there were no differences in PNPase antivities between patients groups and normal subjects. In atopic dermatitis, there were no differences in PNPase activities of sera and erythrocytes between patients group and normal subjects. But, lymphocyte PNPase activities of atopic patients were lowered than those of normal subjects(1.41 +0. 52 unit/10 lymphocytes). In tuberculoid leprosy, there were no differences in lymphocyte PNPase activities between patients group and normal subjects. But, the PNPase activities in sera and erythrocytes of patients group were lowered than those of normal subjects (3. 20. 76) x 104 unit/L, 3. 8n+1.96 unit/107rbc). The PNPase activities in sera((l. 87+/-0. 62) x 104 unit/L), erythrocytes(2. 08+0. 98 unit/107rbc) and lymphocytes (0.51+0. 26 unit/103 lymphocytes) of lepromatous leprosy patients were significantly lowered than those of normal subjects.

We present here a case of phaeornycotic subcutaneous abscess caused by Wangiella dermatitidis in a 34-year-old male, who had multiple asymptomatic subcutaneous masses of 7 months duration over the neck and right axilla. ]n this case, we could observe typical gross colony morphology of W. dermatitidis. which showed creamy greyish, yeast-like colony with aerial mycelia after 3 to 4 weeks. ]n histopathologic study, we found mixed cell granuloma and fungal structure in biopsy specimen. We comfirmed W. dermatitidis by exoantigen test, and treated the subcutaneous lesions by surgical excision and ketoconazole with good result. This case is the first reported in Korea.
