A 13 years old girl came to our department with complaints of multiple ulcerating and non-ulcerating nodules on her back and buttocks since 1 month prior to visit. Skin biopsy specimen showed diffuse monomorphous infiltration of leukemic cells in the dermis and subcutis. Bone marrow biopsy specimen showed changes of erythroleukemia.

A Case of Generalized Perforating Granuloma Annulare / 대한피부과학회지

Generalized perforating granuloma annulare is a rare variant of granuloma. annulare, which was first described by Duncan et al 1) in 1973. A 21-year-old female had hundreds of 3 to 5mm papules over the whole body, which were mainly distributed in the extremities and trunk since three months ago. Individual papules developed a central umbilication with a peripheral collarette of scale. Histopathologic examination showed an epidermal perforation and transepidermal elimination of necrobiotic material. The epidermal perforation communicated with areas of necrobiotic collagen surrounded by palisading granulorna in the dermis. We treated her with oral prednisolone and dapsone, but there was no clinical improvement.

Clinical Evaluation and Patch Test with Vegetables in Housewife' s Hang Eczema / 대한피부과학회지

The importance of vegetables as a allergen for the development of hand eczema has been a matter of debate. The aim of this study was to evaluate the clinical manifestations of hand eczema and to investigate the role of vegetables in the hand eczema of Korean housewives. In this study, clinical evaluatons and patch tests with Hollister-Stier standard allergens and 22 vegetable allergens wer performed in 32 patients with housewife's hand eczema. The results are summarized as follows : 1. The prevalence was highest in fourth(59.4%) and third(25.0%) decades of life and the peak age of onset was third(53.1%) and fourth(31.3%) decades. 2. Only 3 of 32 patients(9.4%) had past histories of atopic dermatitis ; however, childrens of 12 patients(37.5%) had atopic dermatitis. 3. The common skin signs were fissuring(90.6%), scaling(78.1%), erythema(75.0%), hyperkeratosis(71.9%), lichenification(62.5%), and vesicle(43.8%) in descending order. 4. The common aggravating factors were soap or detergent(93.8%), water(90.6%) and rubber glove(25.0%). 5. The most common involved areas of hand eczema were fingers including fingertips and fingertips only. 6. The results of patch test using vegetable allergens with 10 normal controls were all negative. Of the 32 patients with hand eczema, 13(37.5%) showed positive patch test with standard allergens and 5(15.6%) showed positive with vegetable allergens. 7. Among 30 standard allergens, cinnamic alcohol(9.4%). potassium dichromate(9.4%), nickel sulfate(6.3%), and wool wax alcohol(6.3%) were the common allergens which showed positive reactions. Of the 22 vegetable allergens, garlic, Chinese cabbage juice, Chinese cabbage extract, cucumber juice, spinach extract, potato juice showed weak positive reactions in only one patient(3.1%) respectively. From the above results contact sensitivity to vegetables is not significant in Korean housewives with hand eczema.

A Study on the Effect of Various Dosage of Khellin on Epidermal Melanocytes and a Comparison with Trimethylpsoralen in Systemic Photochemotherapy / 대한피부과학회지

Ninety black C 57 BL mice were divided into control and photochemotherapy groups. Control group was subdivided into a UVA 1rradiation only subgroup and a khellin only administration subgroup, while the phototherapy group was subdivided into one TMP and two khellin administration subgroups with dosages of 1.5mg/kg, 5mg/kg and 20mg/kg, respectivly. UVA was administered three thimes a week in a dose of 4J/cm for 4 weeks. Skin biopsies were taken at 0, l, 2, 3 and 4 weeks and the split DOPA stain was employed to observe pigment production. The number, size and circumference of the melanocytes were assessed. In summary, our results inclicate that khellin, which is slightly less effective than TMP at the same effective dose, is quite effective for pigment production and the degree of the production is dose related.

Two Cases of Prurigo Pigmentosa in Korean Women / 대한피부과학회지

Although nearly 100 cases of prurigo pigmentosa have been reported in Japan, there has been no report in Korea. Recently, we exporienced two cases of prurigo pigmentosa in Korean women of 27 and 20 years of age. Histopathological findings of reddish papules showed exocytosis, inter and intra-cellular edema in the epidermis, liquefaction degeneration of the basal cell layei and perivascular round cell infiltration in the dermis. The specimens from the pigmented lesions show merely incontinence of pigments and mild perivascular round cell infiltration. We treated two patients with oral antihistamines and topical corticosteroids. One patient showed complete regression after 8 months of treatment but the other patient was lost for follow up.

A Case of Carcinoma Erysipelatoides Originating in an Internal Organ / 대한피부과학회지

The patient was a 50 year-old female who had peritoneal carcinomatosis, She presented an erythematous lesion resembling erysipelas on her right breast. Histopathologic findings were consistent with metastatic adenocarcinoma but clinically it was not associated with carcinoma of the breast.

A Clinical Evaluation of the Effects of Combination Photochemotherapy in the Treatment of Psoriasis with Etretinate and PUVA / 대한피부과학회지

RePUVA therapy is the combination of an oral aromatic retinoid(etretinate) with oral photochemotherapy (PUVA) for the treatment of psoriasis. This combination therapy has the advantage of faster clearance with fewer side effects. Twenty three ambulatory psoriasis patients received RePUVA treatment. Etretinate was administered in a dosage of approxirnately 0.75 mg/kg body weight for 2 weeks and discontinued. One week after discontinuance of etretinate, PUVA therapy was begun. Complete clearance occured in 96% of the patients with an average of 9.5+4 irradiations and an accumulated ultraviolet A (UVA) dose of 67.5+42 J/cm. The primary side effects were dry rnucous membranes and mild cheilitis. Laboratory findings revealed no significant abnormalities before or after etretinate treatment.
