Bowen's disease is an intraepidermal squarnous cell carcinoma referred to also as squamous cell carcimona in situ. Approximately two-thirds of Bowen's disease consist of solitary lesion while remaining show multiple lesions, We experienced a 68-year old male patient who had multiple erythematous pathes and plaques covered with scales and grayish crusts developing on the trunk and both lower extremities. At first, clinically we suspected psoriasis, seborrheic keratosis, eczema and mycosis fungoides, and finally histopathologic features revealed Bowen's disease showing transformation to invasive squamous cell carcinorna.

A 46-year-old male patient had recurrent episodes of generalized pruritic wheals during hemodialysis. He has experienced urticaria during hemodialysis whenever he used a capillary dialyser sterilized by ethylene oxide(EO, Polysulfone-) gas which is used to sterilize hemodialysers and other medical equipment. On the other hand, capillary dialyser sterilized by Gamma ray (Hemophad) has not evoked urticaria. Although the presence of EO-specific antibodies was not detected, urticarial rash never developed when the equipment was switched to a gamma-sterilized one. We herein report a case referred to ethylene oxide induced cutaneous hypersensitivity during hemodialysis.

BACKGROUND: All though the cause of alopecia areata is not known, many studies have recenty focused on the autoimmunity of alopecia areata. OBJECTIVES: The objectives of this study were to detect autoantibodies against hair follicular antigens and compare the autoantibody level before and after treatment of alopecia areata. METHODS: We collected serum from: (a) 7 alopecia areata patients with good therapeutic responses, (b) 5 alopecia areata patients with poor therapeutic responses (c) 5 normal control people. First, we detected the antigens of hair follicles with SDS-PAGE. Secondly we reacted the antigens with the patients' and normal control serums by Western blotting. RESULTS: The follicular antigens were seen in the range of 44kD-57kD. Autoantibodies obviously apparent in patients of alopecia areata but not in the normal control. High concentrations of were Autoantibodies against follicular antigens seemed to be present in the patients with good therapeutic responses and as they had been treated well, the level of autoantiboies has decreased. Autoantibodies, however, were present in small amounts and were almost an changed between before and after treatment in the patients with poor therapeutic responses except for one case. CONCLUSION: There are kinds of autoantibodies against hair follicles in the serums of alopecia areata patients, and the titers of antibodies may be correlated with therapeutic responses.

Bleomycin, a tumoricidal antibiotic agent, may produce unusual cutaneous manifestations such as pigmentation scleroderma, and gangrene. We report a case of the development of linear streaky pigmentation and cutaneous scleroderma in a patient treated with bleomycin for choriocarcinoma of undescented testis. The patient was 45-year-old male presented with linear brown and slate gray streaking over the trunk and extremities after three cycles of chemotherapy(bleomycin, etoposide, cisplatine). After the fourth cycle of the same chemotherapy, 18 weeks after initiation of bleomycin, the development of cutaneous scleroderma-like conditions was observed involving the same sites. Histopathologic examination showed increased basal pigmentation and thick collagen bundles through the entire dermis, extending to the subcutis. Herein, we describe a case of streaky pigmentation and scleroderma in association with bleomycin anticancer chemotherapy simultaneously in a patient.

We report a case of porokeratosis of Mibelli coexistence with linear porokeratosis in a 28-year old male. He had multiple discrete reddish to brownish annular plaques with peripheral keratotic ridges on the left side of the neck and axilla, and such lesions extended in a linear fashion on the left side of the upper arm and posterior aspect of the lower extremity. The cutaneous lesions started on the left neck and axilla about 6 years prior to consultation. Two years after that, new lesions developed on the left side of the upper arm and lower extremity in a linear fashion. There was no family history of similar skin disorders. A histological examination showed cornoid lamellae in the horny layer. Hypogranulosis, dyskeratotic cells and perivascular mononuclear in-filtrations were also seen beneath the cornoid lamella.

A 49-year-old Caucasian male patient suffered from fever general weakness and diffuse hair loss on the scalp for 3 days. Skin lesions showed erythematous scaly patches with pustules and erosions on the lower extremities and perianal region, and multiple ulcerations on the labial mucoas. A complete blood cell count revealed thrombocytopenia and leukopenia, which gradually worsened day after day (platelet: 29, 000/mm², WBC: 1,000/mm³). Candida albicans was isolated from the lesions of the oral cavity and lower extremities. Twelve days prior to the visit, he had taken etretinate Tegison®) P.O.25mg/day, prednisolone P.O. 50mg1dy and methotrexate P.O. 15mg/day for 5 days for the treatment of psoriasis. We presume that these adverse reactions may be synergistic adverse reactions, probably due to methotrexate and etretinate in consideration of the patient's history.

Two cases of epidermal nevi treated with systemic etretinate are presented. Case 1, a 21-year-old female, had been suffered from brownish verrucous papules and plaques on the left inguinal area, thigh, lower leg and dorsum of the foot since her first month of life; and case 2, a 4-year-old boy, had been suffered from brownish verrucous papular plaques on the left chest, axilla and back since birth. In both cases, there was no family history of similar disease. On histopathological examination, case 1 showed the findings of epidermolytic. hyperkeratosis but case 2 did not, with the exception of clumping of keratohyaline granules. In the treatment with systemic etretinate, we observed marked clinical improvement in case 1, but not in case 2. Any particular side effects of etretinate were not observed during treatment. We consider that etretinate therapy is useful in treating epidermal nevus with epidermolytic hyperkeratosis histopathologically.

BACKGROUND: Skin cancers arc the most common malignancies in human. The increasing incidence of skin cancer has been attributed to increasing exposure of the papulation to sunlight and other factors, such as chemicals or. viruses. OBJECTIVE: The purpose of this study is to investigate a recent 10 year period(1984-1993) of clinical observation of cutaneous malignant tumors. METHODS: A statistical study was made with 60 cases of malignant tumors that visited the Departrnent of Dermatology, Chung Ang University during a 10 year period(1984-1993). RESULTS: 1. The mean incidence of cutlneous malignant tumors in the total number of outpatients was 0.16%(60/36,416). The incidence of malignant turnors has tended to increase in the last 4 years. 2. The age of onset was quite varied but the majority of cases, 51 cases(85.0%), were over 40 years old. The ratio of rnen to women was 1.3: 1.3. Among the 60 cases of malignant cutaneous tumors, the most frequently observed tumor was basal cell carcinoma, 20 cases(33.3% ). The next most frequent tumors were squamous cell carcinoma, 9 cases(15.0%), metastatic carcinoma, 9 cases(15.0%) and malignant melanoma, 6 cases(10.0%). 4. Among the 20 cases of basal cell carcinoma, 19 cases(95.0%) were over 40 years old. The most frequent age was the 7th decade(30.0%). The most common predilection sites were the nose (30.0%), the cheek(20.0%) and the eyelid(10.0%). 5. Among the 9 cases of squamous cell carcinoma, 8 cases(88.9% ) were over 40 years old. The ratio of men to women was 1: 2. The most frequent age was the 8th decade(44.4% ). The most common predilection sites were the head(55.6%), lower extremity(22.2%), upper extremity (11.1%) and trunk(11.1%). 6. All patients with malignant melanoma were over 40 years old. The most frequent age was the 5th decade(50.0%). The most cornmon predilection sites were the upper and lower extremities (66.7% ). 7. Among the 9 cases of metastatic carcinoma, 7 cases(77.8%) were over 40 years old. The ratio of men to women was 1: 1.25. The most frequent primary tumor was stomach cancer in men and lung cancer in women. 8. Cutaneous malignant tumor. usually had no detectable metastasis but there were 2 cases of extramammary Pagets disease with metastasis in the regional lymph nodes. CONCLUSIONS : This study revealed that the incidence of malignant tumors has tended to increase over the last few years, the most frequent age was over 40 years old, the most observed turnor was basal cell carcinoma and any type of cutaneous malignant tumors was rarely metastasis.
