A Clinicopathological Study of Leukemia Cutis / 대한피부과학회지

A clinicopathological study was made on 17 case with leukemia cutis diagnosed in a period of 10 years frorn 1980 to 1989 in Seoul Xational University I-lospital. The results were summarized as follows : 1. There were 4 cases with acute lyrnphocytic leukernia, 7 with acute myelocytir. leukemia (AML), 5 with chronic myelocytic leukemia (CML), 1 with eosinophilic leukemia. 2. The clinical appearance of leukemia cutis included nodules (88.2%), papules, macules, plaques and ulcerative lesions. Leukemia cutis dis not show any discernible clinical qppearance with each different type of leukemia. 3. Leukemia cutis showed a wide spectrum of histopathologic features, diffuse infiltration, patchy infiltration with linear infiltration between collagen bundles, perivascular and peridnexal involvement, perivascular involvement, and mainly subcutaneous tissue involvement. There was no distinctive histopathologic pattern with each different type of leukemia. 4. The demonstration of intracytoplasmic chloroacetate esterase and lysozyme was helpful to refine the diagnosis of leukemia cutis.

Association Between Psoriasis and HLA - B27 Antigen / 대한피부과학회지

The frequency of HLA-B27 antigen in 24 patients with psoriasis vulgaris and 11 patients with psoriatic arthritis were examined using the standard micro-lympho- cytotoxicity technique. There was a high frequency of HLA-B27 in psoriatic spondylitis with or without peripheral arthritis (83.3%) compared to controls (4.7%) and the relative risk of HLA-B27 for developing psoriatic spondylitis was 82.5% which indicates a strong association between HLA-B27 and psoriatic spondylitis in Korean populations. However, there was no stastical significance observed in the groups of patients with peripheral arthritis alone or psoriasis vulgaris in regard to the frequency of HLA-B27.

Two Cases of Allergic contact Dermatitis due to Paratertiary Butyphenol Formaldehyde Resin - Containing Shoes / 대한피부과학회지

The paratertiary butylphenol formaldehyde resin (PTBP-FR) is commonly used as a shoe adhesives because it sticks rapidly, is durable and pliable, and maintains good bond strength at raised temperature. We report two cases of allergic contact dermatitis due to PTBP-FR-containing shoes. Two women visited our department because of the skin rash on their .

A Case of Lentigo Maligna Melanoma / 대한피부과학회지

Herein we report a case of lentigo maligna that evolved into lentigo maligna melanoma. Fifteen years ago, the patient developed a pigmented lesion on the right cheek. The lesion progressed slowly, and 2 months ago, a black nodular lesion was developed in the periphery of the pigmented lesion. Histopathologic examination of the lesions revealed findings consistent with lentigo maligna and lentigo maligna melanorna. She had been performed wide excision and cheek flap for reconstruction.

Inflammatory Skin Response to Ultraviolet Radiation: Ear Swelling Response in C57BL Mouse / 대한피부과학회지

This study was undertaken to investigate the change of ear swelling response (ESR) of the mice according to repetitive ultraviolet radiation. 100mJ/crn of UVB was irradiated daily for 4 weeks, and a total of 25 C57BL mice were used as subjects. The results were as follows : 1. After 1 day, 2 days and 3 days irradiation of UVB, ESR reached 21.3+/-1.5, 22.3+/-1.1 and 24.3+/-1.6 respectively with increasing tendency, but there was no statistical significance (Wilcoxon rank sum test p>0.05). 2. ESR reached at maximum, 78.0+/-1.8, after 1 week(p<0.01), thereafter ESR decreased gradually with reparative process. 3. Inspite of continued irradiation, ESR decreased gradually after 2 weeks. After 2 weeks, 3 weeks and 4 weeks irradiation, ESR decreased to 51.6+/-11.8, 45.1+/- 3.3 and 42.8+/-6.8 respectively, but, there were still increment of ESR (p<0.01).

Two Cases of Lacalized Cutaneous Amyloidosis Associated with Neurodermatitis / 대한피부과학회지

We report herein two cases of localized curaneous amyloidosis (LCA) associated with neurodermatitis. Both patients suffered from persistent pruritus during several years and had small brown discrete lichenoid papules or neurodermatitis like lesion. Biopsy specimen taken from lichehoid papules revealed amyloid deposition in the papillary dermis. In histologic examination of the neurodermatitis like lesion, hematoxylin eosin stain revealed only chronic eczematous changes but special stain and election microscopic examination revealed amyloid deposition in the papillary dermis. Although neurodermatitis and LCA may be able to develop concomitantly in one patient, it was suggested that neurodermatitis may transfrom into LCA.
