Factor VIII Related Antigen in Granuloma Pyogenicum / 대한피부과학회지

Using Avidin-Biotin immunoperaxidase method, we investigate the distribution patterns of factor VIII related antigen in various areas of skin lesions of 14 granuloma pyogenicum. and in the skin lesions of 5 capillary hemangioma and 5 normal skin. The results are summarized as follows: 1. Factor VIII related antigen was detected in 9 of 14 cases of granuloma pyogenicum, in 4 of 5 cases of capillary hemangioma, and in 5 of 5 cases of normal skin. 2. In the lesions of granuloma pyogenicum the areas with prominent capillary endothelial cell proliferation had less positivity than the vascular areas. And the areas with relatively large vesels in the lesions of granuloma pyogenicum had similar positivity as capillary hemangioma. 3. The lesions of granuloma pyogenicum and capillary hemangioma had less positivity than the vessels of normal derrnis.

Two Cases of Lichen Planus / 대한피부과학회지

We have experienced 2 cases of lichen planus. Case 1 was a. 76-year-old male who has suffered from discrete, scaly, round to polygonal papules on the trunk and the e:xtremiities for 3 months. The VDRL test for syphilis was reactive at a titer of 1:2 and the TPHA test was positive. The skin lesions were responded to 3 weekly injections of benzathine penicillin 2.4 million units, Case 2 was a 17-year-old male who has suffered from discrete, erythematous to violaceous colored, flat papules on the right shin for several months. He has treated with oral medication of griseofulvin. After 2 weeks of the medication, the skin ]esions showed improvement with gradual reduction of pruritus and flattening of the papules. About one month of the medication, all skin lesions cliappeared with dark brownish hue and hypopigmentation. And recurreci lesions after stopping medication are disappeared after 2 months of retreatment with griseofulvin.

Two Cases of Extramammar Paget's Disease / 대한피부과학회지

We have experienced two cases of extramammary Paget's disease. The first case was a 68-year-old male who showed erythematous, crusted, oozing, eczematoid patches on the scroturn, penile root and pubic area, and verrucous plaque on the left pubic area of 5 years' duration. The second case was a 60-year-old male who showed erythematous, oozing, hyperkeratotic plaque and nodular mass on the scrotum of 4 years' duration. In electron microscopic findings of the first case, the Paget's cells was suggested to be formed by pleuripotential germinative cells; well developed microvilli, numerous electron lucent secretory granules, a few electron dense granules, apocrine type secretion and well developed desmosome.

A Case of Toxic Erythema, Toxic Hepatitis and Exfoliative Deratitis due to Trichloroethylene / 대한피부과학회지

Trichloroethylene is a very common chemical used principally as a solvent and a degreasing agent in industry, We have experienced a case of toxic erythema, toxic hepatitis, and subsequent exfoliative dermatitis possibly due to trichloroethylene in a 23-year-old male. He had dealed with a cleaning process with trichloroethylene in a factory of stainless steel materials. We report our case with the review of the toxicity of trichoroethylene.

Four Cases Which were Mis-diagnosed as Granuloma Pyogenicum / 대한피부과학회지

We have experienced 4 cases which were clinically diagncsed as granuloma pyogenicum, but histologically as a malignant melanorna, an eccrine angiomatous hamartoma with granuloma pyogenicum, a subungual exostosis, and a lipoma, with granulation tissue. A granuloma pyogenicum may have clinical resemblances to various benign or malignant lesions. Therefore, any lesion that resembles a granuloma pyogenicum should have this clinical impression confirmed by histologic examination.

A Case of Chilblain Lupus Erythematosus / 대한피부과학회지

Chilblain lupus erythematosus(CLE) is a chronic unremitting from of LE seen predomin antly in women, The chilblain lesion occurs commonly on the digits, calves and heels. Chronic facial discoid LE usually appears before the chilblain form. A 23-year-old female had relatively well defined, erythematous discoid plaques on her both cheeks and scattered erythema multiforme-like ring lesions on her right hand and right wrist. There were also chilblain lesions showing multiple, purple colored macules on her knees, lower legs and periungual areas of fingers and toes. The skin lesions developed at November, 1982 and then the skin lesions remitted during the next summer. The skin lesions recurred at December, 1983.
