Epithelioma cuniculatum or plantar verrucous carcinoma shows a great tendency toward deep penetrating growth, resulting in numerous crypts filled with horny material and pus. We herein described a 44 year-old female who showed a warty, relatively round, brown to yellow colored protruding mass with many crypts filled with pus-like exudates, measuring 2.3 X 2.5 X 1.5 cm in size, and of 5 years duration. The biopsy specimen taken from the tumor mass revealed a deeply penetrating, well-differentiated squarnous cell carcinoma without nuclear anaplasia and individual cell keratinization.

The clinical observation was done on 9 patients of incontinentia pigmenti(I,P.) who were seen at the Department of Dermatology, Chonnam University Hospital from January, 1970 through December, 1982. The incidence of I.P. patients among the population of Chonnam province was higher than 1/142,000 whereas the frequency of I.P. among the outpatients was 0.016% The sex of I.P. patients was all female and there was no cases showing faiailial occurrence. The onset of the cases were within 4 months after birth, 44%, being at birth and 89% being within 2 weeks after birth. The durations of first, second and third stages of I.P. patients were respectively 14 days, 15 days to 2 months, and 2 months to 10 months. The trunk and extremities were involved in 4 cases, and the extremities only were involved in 4 cases while the trunk only was involved in J case. The blood eosinophilia was observed in 2 cases among 7 cases, with their results being 18%, and 11% respectively. The biopsy examinations done in 7 cases at the time of their first visits revealed that 3 cases, 2 cases and 1 case respectively conformed to first, second and third stages with 1 case having first and second stages simu 1taneously. There was no I.P. patient showing the associated congenital abnorma- lity.

BACKGROUND: The sunburn cell is an abnormal keratinocyte of the skin induced by ultraviolet (UV) irradiation, and is used as an indicator of cell damage. The sunburn cell is consideredas an apoptotic cell which has been caused by UV irradiation, and many studies have been performed to understand the mechanism of photodamage in relation to apoptosis. The mechanism of photodamage by UV irradiation is still unclear. However, it is suggested that oxygen stress by reactive oxygen species produced by the UV rays may play an important role. OBJECTIVE: This study was a med at evaluating whether various antioxidants and sunscreen can prevent sunburn cell formation. In addition, we studied whether or not the sunburn cell is identical to an apoptotic cell stained using the TUNEL method. METHODS: White mice (ICR strain) were used to test the potency of various topical agents which are used in the prevention of sunburn cell formation; the agents were various antioxidants of L-ascorbic acid, tocopherol, catalase, a reduced form of glutathione (GSH), and sunscreen PABA (para-amino benzoic acid). Each agent was topically applied daily for 5 consecutive days on the dorsal skin of the ears. 300 mJ/cm of UV-B was irradiated on the ears 30 mins after the final applicaion, and skin samples were taken 24 hrs after that. The sunburn cells in the H & E stain were counted per 1 mm under the microscope. Also, the same sections for the sunburn cell study were stained by the TUNEL method using the ApopTag In Situ Apoptosis Detection Kit (Oncor, Inc.). RESULTS: The number of sunburn cells increased in a UV-B dosage-dependent. manner up to 300 mJ/cm2. The potency in the reduction of sunburn cell formation was as follows in order,PABA (0.37 +/- 0,5), GSH (0.87 +/- 0.5), ascorbic acid (1.62 +/- 0.85) and tocopherol (1.75 +/- 1.12). However catalase (2.93 +/- 1.56) did not show any protective effect. Also, the finding that sunburn cells were the same as TUNEL-positive cells confirmed the notion that the sunburn cell is a kind of apototic cell. CONCLUSION: A sunburn cell is a kind of apoptotic cell that may be caused by reactive oxygen species induced by UV-B irradiation, in view of the fact that sunburn cell formation was inhibited by the topical application of various antioxidants. But the result that physical protection by PABA has the most potent protective effect in relation to sun damage suggests that protection using a combined physical and biochemical approach is important in the development of new topical agents which will inhibit sundamage to the skin.

This study was done to report the epidemiologic characteristics of medical retirement from the Republic of Korea (ROK) Army due to visual impairment and to suggest a practical screening system for the draft. The medical records of 423 eyes of 301 patients who retired from the ROK Army due to visual impairment were reviewed retrospectively between January 2010 and December 2014. The patients were grouped by the presence of trauma, and each group was subdivided by military rank. We analyzed demographic and ophthalmic data, including the etiology of ophthalmologic disease. The etiology was classified into 5 anatomical categories (ocular surface, lens, retina, optic nerve and extraocular visual pathway, and extraocular muscle and orbit), which were then subdivided into the type of disease. The mean age was 24.5 years, and non-traumatic mechanisms accounted for 81.1% (343/423 eyes) of medical retirements. Visual acuity was better in patients without trauma. In enlisted soldiers, disease in the optic nerve and extraocular visual pathway was the most common anatomical category (40.5%), and primary open angle glaucoma (30.8%), retinal dystrophy (18.3%), congenital cataract (14.5%), and retinal detachment (9.7%) were the four most common diseases. Most medical retirements due to visual impairment resulted from non-traumatic mechanisms, even though patients were young. The fundus examination and visual field test would be more useful tools than a conventional vision test for large-scale draft screening for the most common two disease types: primary open angle glaucoma and retinal dystrophy.

Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

We have used BALB/c mice as an animal model for the study of anaphylactic hypersensitivity to the house dust mite. For the sensitization, BALB/c mice were injected with a single dose of extracts of Oermatophagoides farinae (D. pa) or Dermatophagoides pteronyssinus (D. pt) mixed with adjuvants (aluminum hydroxide and Bordetella pertussis) intraperitonealy. On days of 15, 30, and 60 after the sensitization, the mice received a challenge dose of the same allergen intravenously to induce anaphylactic shock. The hypersensitivity reactions were scored by anaphylactic shock. And various immunological parameters, including cytokines and immunoglobulin isotypes, were studied in relation with the shock. A high level of anaphylactic shock was produced in the mice by both of the allergens, D, fa and D, pt, at 15 and 30 days after sensitization. In vitro Ag specific proliferative reponses of spleen cells from D. pt treated mice (D. pt mice) was six times higher than those from O. fa treated mice (O. fa mice). Regardless the differences in antigens, the production of IFN-r by spleen cells from D. pt mice or O. fa mice was equally high at 15 days after sensitization. However, the ability to produce IFN-r by the spleen cells from D, pt mice was three times higher compared to that from D. fa mice. The production of IL-4 by the spleen cells was enhanced slightly but not significant in both groups. In studies of the allergen-specific immunoglobulin isotypes in the sera of the mice, the level of IgE in both groups was enhanced slightly but not significant. In contrast, the level of IgG subtypes were increased in both groups. When the levels of IgG were compared by subtypes, the level of IgG1 increased significantly on day 15 when the anaphylactic shock score was maximized in both groups. Increase in IgG2a level at the day was not significant, instead, asignificant increase in IgG2 levels was observed on day 60 after sensitization when the anaphylaxis was almost discontinued. Although a higher level of IgG3 was examined on day 15 and 30 in D. pt mice and on day 60 in D, fa mice, anaphylaxis was not appeared to be associated with the levels of IgG3 in this study. The IgG1, rather than IgE, was assumed to the major factor involved in the anaphylactic response observed in this experiment. In conclusion, BALB/c mice would be an animal model for the study of anaphylactic hypersensitivity to D. fa or D, pt., which might be an essential tool for the future development of immuno-therapeutic agents.
