A case of toxic epidermal necrolysis (TEN) was presented in 46 year-old male patient. The characteristic skin lesions of TEN were developed after some medictions and tetanus anti-toxin (TAT) injection due to trauma. Probably, the cause of the disease was drugs, TAT injection or trauma inself. On the pathologic findings, lower epidermis and dermo-epidermal cleavage were noticed. He was treated with massive antibiotics and steroid. About 7 days after therapy, much improvement achived. However foul odorous yellowish discharge was noticed since 20 days of hospitalization. Wide debridement of necrotic tissue was carried without improvement. Patient expired on 48th hospital day due to sepsis and impending hepatic coma.

Incontinentia pigmenti is an uncommon genodermatosis. It affects female infants predominantly, described first by Bardach in l925, with the diagnosis of systematized nevus and Bloch in 1926, and Sulzberger in 1928 rnore compIetely. Skin lesions are characterized by 3 stages such as vesicobullous, verucous and finally pigmentary lesions and leave brownish pigmentation on the extremities and trunk. Hesides skin lesions some ectodermaI and mesodermal organs are affected and show developmental abnormalities. We experienced a case of incontinentia pigmenti in a 45-day-old female infant and present it with the review of literature. She showed extensive vesicobullopustular eruption with linear and reticular pigmentation on the extremities and trunk. Clinical and histopathologic findings of these lesions are compatible with Bloch-Sulzberger type of incontinentia pigmenti.

Serum zinc is an essential element in men and animals. Recently on the dermatologic fields, the serum and the skin levels and the roles of zinc have been studied especially in acne vulgaris, but the results were controversial. So to confirm the previous reports and for evaluation of the relationship between the various aspects of acne vulgaris and the serum levels of zinc, the serum levels of zinc were measured by atomic absorption spectrophotometer in 13 healthy controls and 46 patients with acne vulgaris. In the healthy controls, their mean values of zinc were 0.843+0.251 ppm in total, 0.920+0.219 ppm, in females and 0.777+0.260 ppm in males. There was no statistical difference attributable to sex. In the 46 patients with acne vulgaris, their mean value of zinc was 0.741+0.195 ppm. There was no significant difference in the mean serum zinc level compared with the controls. In the males with acne, the mean va1ue of zinc was 0.727+0.166 ppm, and 0.748+0.208 ppm in females with acne. There was no significant statistical difference between males and females with acne. And females, but not males, with acne had significantly lower serum zinc levelss than controls of the corresponding sex. (p<0.1) By clinical severity, classifying the 46 patients with acne vulgaris into three groups: mild type (only comedones), moderate type (comedones with pa.pules) and severe type (includes pustules, comedones, and papules, etc.), the serum zinc levels of each group were 0.774+0.185 ppm, 0.7880. 200 ppm and 0.666+0.176 ppm. The significant statistical difference was found only in the severe type of acne compared with the healthy controls (p<0.05). Also classifying the patients into three groups (acute, moderate and chronic types of acne) by duration of acne, the serum values of zinc were 0.738+0.158 ppm, 0.692+0.283 ppm and 0.769+0.241 ppm, respectively. Only in the moderate type of acne, the mean serum level of zinc was significantly reduced compared with the control group (p<0.1)

The early ultrastructural changes of basement membrane thickening and degeneration of the pericyte were noted in retinal capillaries in diabetic patients. However no early ultrastructural changes were reported in diabetic iris capillary. The authors studied the ultrastructural features of basement membrane of iris capillaries which were obtained during cataract surgery in five diabetic patients and compared with those obtained in five nondiabetic patients. The endothelium basal lamina, pericyte basal lamina and membrane-like pericyte matrix in didabetic iris capillaries were thicker than those in nondiabetic Iris capillaries. The thickening of pericyte basal lamina is more prominant than the endothelium basal lamina in diabetes. The duration of diabetes had no relationship to endothelium basal lamina but, showed statistically significant relationship to thickness of pericyte bascal lamina and pericyte matrix.

PURPOSE: To clarify the chracteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. MATERIALS AND METHODS: We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. RESULTS: The tumors included 33 lipomas, 11 hemangiomas. 11 lymphangiomas, 7 neurilemmomas, 4 epidermold cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The SOhographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxoma), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and chacteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymphangioma. Neurilemmoma showed Iobulated, oval to round, relatively hypoechoic mass with or without internal cystic portion. CONCLUSION: Sonographic evaluation of benign soft tissue tumros is useful in demonstrating the location, size, extent, and internal characteristics of the mass. A relatively confident diagnosis can be made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging.

PURPOSE: The aims of this study are to compare the results of renal retransplantation and the first renal transplantation in our center, and to analyze the risk factor affecting second graft survival rate. METHODS: We analyzed 37 cases of second or third renal transplantations performed in our center from 1981 to 2005, retrospectively. We compared the second graft survival rate with the first graft survival rate. And risk factors affecting long-term second graft survival were also analyzed. RESULTS: 37 cases of retransplantation out of 277 cases of first graft loss were performed in our center (5%). Second graft survival rates (1, 5, 10 year) were 83.7, 66.5, 49.9%, while first graft survival rates were 90.0, 74.8, 59.1%, repectively. Risk factors which shows significance were high HLA-AB matching, living donor and absence of DGF. CONCLUSION: The graft survival rates of second renal transplantation were similar to that of first renal transplantantation.

PURPOSE: The availability of living donors is the major limiting factor in living related kidney transplantion. In 1997, Ross et al. proposed that the living unrelated kidney transplantation through exchange arrangement of ABO-incompatible donors-recipient pairs to expand donor pool is ethically acceptable as living related kidney transplantation. We analyzed exchange donor program whether this could expand the kidney donor pool in living donor renal transplantation. METHODS: We retrospectively reviewed the records of the 121 exchange donor renal transplantations performed from 1991 to 2005 in our center. Recipient's and donor's mean age were 38.8 (15~64) and 40.4 (21~60) year-old, respectively. Mean follow up period is 81 months (1~170). The reasons of exchanging donor were ABO incompatibility (92/121, 76%), positive HLA cross matching (20/121, 16%) and patients who received kidneys from unknown volunteer donors (9/121, 7%). We compared graft survival and acute rejection rate of exchange donor group and living related donor group. RESULTS: The graft survival rate (1, 5, 10 year) of exchange donor group (92%, 80.6%, 72%) was similar to living related donor groups (95%, 77%, 66%). The acute rejection rate were 34% (42/121 ) and 24%, respectively. We have observed acute rejections during the same time in both groups from 1991 to 2005. Although acute rejection rate of exchange donor group is higher, we see the similar survival rate of transplanted kidneys in exchange donor group. CONCLUSION: We suggest that exchange donor program could expand the donor pool in living donor renal transplantation, when recipient cannot receive kidney from healthy donor because of ABO incompatibility or positive HLA cross matching.

Authors performed film mammography in 2167 patients with breast complaints who had visited to Yong DongSeverance hospital, Yonsei University from October 1, 1983 to September 30, 1985. Authors analysed 62 cases offilm mammographic findings and 35 cases of ultra mammographic findings among confirmed 62 fibroadenomas and alsoauthors analysed histopathologic cell type and ultra mammographic findings of confirmed fibroadenomas. The resultsfollowed: 1. The most prevalent age group was 3rd and 4th decade(74%). 2. The common dense breast pattern by Wolfeclassification were P2 and DY patterns(80%) in film mammograhy. 3. The most common size of fibroadenomas was1.1-3.0cm (71%) in long diameter. 4. Film mammographic findings of fibroadenoma generally showed single mass in 54lesions(87%), well defined margin of mass in 45 lesions (58%) and halo sign in 62 lesions(80%). Well definedmargin of mass is prominant in ductal cell dominant fibroadenoma(71%) , however lobulation of margin is commonlyseen instromal component dominant fibroadenoma(15%) and spiculated margins of mass can be seen in mixedfibroadenoma(6%) and stromal component dominant fibroadenoma(3%). Halo sing of fibroadenoma was commonly seen inductal cell dominant fibroadenoma(86%) and stomal component dominant fibroadenoma(85%). 5. Ultra mammographicfindings of fibroadenoma showed oval shaped mass in 26 lesions(15%) with smooth margin of mass in 43 lesions(84%)and showed mostly intermediate internal echo in 48 lesions(94%). Relationship between histopathologic cell typeand ultra mammographic findings were. Round shaped mass(67%), lateral shadowing (74%) was common in mixed type offibroadenoma, lobulated margin of mass(45%), intermediate(94%) with unifrorm(78%) internal echo was common instromal dominant type of fibroadenoma and smooth contour (100%), uniform internal echo fo mass(83%) was common inductal cell dominant type of fibroadenoma. Most ultra mammographic L/T Iratio of fibroadenoma was 0.5-1.0 in 37lesions(73%) 6. The diagnostic accuracy of film mammogahy in fibroadenoma was 92%, however combined imagingmodalities raised the diagnostic accuracy into 95%.
