Pigmented Bowen's disease (PBD) is a rare variant of Bowen's disease(BD). Most of the reported cases showed pigmented patches or thin plaques. Thus its clinical manifestations may simulated other various pigmented skin lesions. We experienced 2 cases of PBD in patients with multiple BD developed after taking Korean proprietary pills (KPP, "Hwan-Yak"), which were suspected to contain certain amount of arsenics. Both patients also showed arsenical keratosis on their palms and soles. The darker pigmentation of the PBL led us to differentiated them from melanoma.

BACKGROUND: Keloids may occur at any age, but tend tend velop between the ages of 10 and 30. The incidence and median age of onset are equal for both sexes. Keloids are common among the darker pigmented rices, but there have been a few clinia studies of keloids in Korea. OBJECTIVE: The purpcse of this study was to evaluate the variable clinical characteristics of keloids in Korea. METHODS: This clinical investigation was made with 223 of patients of keloid who had visited the Department of Derrnatology, Chonnam University Hosptal from January 1984 to December 1993. RESULTS: 1.The annual incidenie averaged over 10 years was 0.831 (361 cases of total 43,752 outpatients). 2.The ratio of male to female was 1: 0.94(Male. 115, Feila 108). 3.The mean age of the onset and at the first visit to our hospital were 24.5years and 29.2 years respectively. 4.In our series tte presternal area was the most commor saes, the shouder region next. Most keloids on the shoulder were related to BCG vaccination in ifoncy or chilhood. 5.The precipitating fa ctors associated with keloid were riaeeding dermatologic diseases(33.2 %), unknown(17.9%) rejection & vaccination(15.2%), operation(13.9%), burn(13.9%) and laceration(5.8%) in descending order. 6.Among preceeding as, iociated dermatologic diseases, acne w s the most common. 7. A positive family history is more likely in cases of mitile keloidal (p<0,001), and severe keloidal formation. 8.Most patients did not. complain of any symptorns(45.3%) nd a symptom of pain or tenderness(40.8%) was piesert rather than pruritus(13.9%). 9.The most prevaent tr eatment modality was intralesional injection with triamcinolone acetonide (84.3%). CONCLUSION: According, to this study, usually keloids occore in patients between 10 and 29 years of age, and most keloids were located on the antetio partion of the chest, shoulders, and face and scalp. A positive family history is more likely in as of multiple, severe keloidal for mation.

OBJECTIVES: The diagnosis of ASCUS(atypical squamous cells of undetermined significance) and LSIL(low-grade squamous intraepithelial lesion) was introduced in 1988 by the Bethesda system for reporting cervical/vaginal cytologies. A significant proportion of women referred for colposcopy with low grade cervical cytologic abnormalities(ASCUS and LSIL) will have high grade cervical intraepithelial neoplasia(CIN II or CIN III) and therefore require adequate management. The purposes of this study were to evaluate the usefulness of high risk type HPV(human papillomavirus) DNA detection using PCR(polyerase chain reaction) in patients with low grade cervical cytologic abnormalities in the prediction of high grade CIN and invasive cancer and to determine the clinical triage in the management of low grade cervical cytologic abnormalities. METHODS: We reviewed 18,942 cases of Papanicolau smears that were performed at our hospital from Jan. 1995 to Mar. 1999. Colposcopically directed biopsy or LLETZ(large loop excision of transformation zone) or hysterectomy were performed on 318 patients with abnormal PAP smears of low degree. HPV PCR testing of high risk types(16 and 18) was also performed on 115 patients. RESULTS: Histologic outcome of ASCUS included 43 cases(38.4%) of high grade CIN and invasive cancer, and that of LSIL included 65 cases(47.5%) of high grade CIN and invasive cancer. In cases of high risk HPV type, 19 patients(73.1%) were at age over 30 years. A highly significant correlation was found between a positive test for high risk types of HPV and finding of high grade CIN and invasive cancer. Among 51 women with ASCUS, a positive test for high risk type had a sensitivity and specificity of 40.0% and 86.1%, and positive predictive value(PPV) and negative predictive value(NPV) of 54.5% and 77.5%, respectively. In 64 women with LSIL, a positive high risk type test was associated with sensitivity and specificity of 30.0% and 94.1%, and PPV and NPV of 81.8% and 60.4%, respectively. CONCLUSION: Our results suggest that high risk type HPV may be positively predictive of and may act as a surrogate marker for high grade CIN and invasive cancer in women with low grade cervical cytologic abnormalities. The management of women with a low grade cervical cytologic abnormalities should be active such as colposcopically directed biopsies.

Nocodazole is an anticancer agent, well-known for its antimetastatic activity that acts on microtubules, microfilaments and extracellular matrix proteins. Hela, Hep G2, A549, L929, and NIH/3T3 cell lines were cultivated in alpha-MEM with 3microM or 30microM nocodazole. To investigate the mechanism of nocodazole preventing tumor cell metastasis, the influences of nocodazole on the amounts of glycoprotein, fibronectin, laminin and actin were investigated using PAS staining and PAP technique at light microscopic level. Two designed models ; coverglass and 3-day-old rat heart fragments models, were used in observing the invasiveness of cancer cells. Partitularly the three-dimensional model coculturing cell lines and heart fragment was used in evaluating the migration and/or proliferation or the invasiveness of cell around the fragment, and observed under inverted or bright field light microscope. The amount of glycoprotein of all cell-lines increased in cells of groups treated with nocedazole for 1, 2 and 3 day. The amounts of fibronectin usually increased in cells of groups treated with nocodazole for 1, 2 and 3 day. The amounts of laminin increased in cells of groups treated with nocodazole. The amounts of actin usually increased in cells of groups treated with nocodazole for 1, 2 and 3 days. With the prolonging of nocodazole-treatment time in two dimensional model using coverglass, the cells of control group except Hep G2 cells formed monolayer in cell-free zone according to migration or proliferation of many cells. But only a few cells of experimental groups migrated or proliferated into cell-free zone. In rat heart fragment model the cells of control group showed the invasiveness into the fragment but few or none of the cells from experimental groups attached around the fragment. Taken together, nocodazole increased the synthesis of fibronectin and laminin in cells in place of depolymerizing microtubules. Therefore, the amounts of extracellular matrix proteins in the extracellular space increased. And the increase amounts of actin connected to the extracellular matrix proteins through the integrin of plasma membrane seemed to strengthen cell attachment because of accordance between the orientation of actin and extracellular matrix proteins. Since it is important for cancer cells` metastasis to secrete various enzymes to pass through extracellular matrix proteins, it is expected more difficult for the cells to metastasize into other regions due to the increase of extracellular matrix proteins. As a result of confirmation of antiinvasive actions using two kinds of model, nocodazole seems to be a valuable anti-metastatic agent by supressing the cell motility and consequently, the invasiveness into the fragment. Nocodazole at concentration of 3microM will be probably anticipated antimetastatic activity reflecting that the effects of nocodazole between 3microM and 30microM groups had no differences.

The compartment syndrome was described by von Volkmann in 1872 and numerous reports have since been published. The anterior tibial syndrome is well known, but the peroneal compartment syndrome is very rare and have some differences in it's etiology, diagnosis and treatment. We experienced a case of the peroneal compartment syndrome developed after playing foot-ball, and treated by fasciotomy with some delay, but obtained a satisfactory functional result.

We observed 2 cases of occupational radiodermatitis which occurred during the radioisotope transpierce test. Patient 1, a 40-year-old man, noticed swelling, erythema, and stiffness on his left 2nd, 3rd, 4th, and 5th fingers 5 days after the exposure to about 2700 rem. Patient 2, a 32-year-old man, noticed painful swelling, erythema, bullae and necrosis on his right palm and thumb 1 week after the exposure to about 5500 rem. Clinicopathologically, patient 1 and 2 came under 2 and 3 burns respectively. The symptoms have been improving after treatment with systemic and topical corticosteroids and antibiotics.

We observed a family with 12 members in four consecutive generations affected by hereditary epidermolytic palmoplantar keratoderma(HEPPK). The affected family members demonstrated not only autosomal dominant inheritance, but also a high penetrance and constant expression. The lesion of all affected person had developed at birth or within the first few weeks of life. The lesions of three members(the proband, her sister and mother) were biopsed, and all of them showed the characteristic features of epidermolytic hyperkeratosis. Two of family members(the proband, her nephew-not affected by HEPPK) had vitiligo, but we concluded that this coexistance was accidental.
