To pursue a desirable format for the pathological diagnosis of liver cirrhosis, the authors attempted to classify 369 biopsy-proven cirrhosis on the basis of etiology and made effort to find out the morphological characteristics of each category. About 735 of total cases were HBsAg seropositive postnecrotic cirrhosis. Alcholic cirrhosis ws the second most frequent type, although accounted only 6.8%. In about 15%, the etiology was not known. Excluding the congenital biliary atresia, chronic biliary obstruction appeared to be a rare cause of cirrhosis among these biopsied cases. Of the HBsAg positive postnecrotic cirrhosis, the eAg seropositive cases tended to be micronodular and to show a higher necroinflammatory activity, in contrast to eAg seronegative cases and those complicated by hepatocellular carcinoma (HCC), suggesting that the loss of eAg is followed by a decrease of the destructive activity, active regeneration of hepatocytes and finally the development of HCC. alcoholic cirrhosis was micronodular in 64% and revealed histologic evidences of alcoholic liver disease in most cases. The results indicate that etiological diagnosis can be made in most cases of cirrhosis by the morphological characteristics and the precise clinical informations, including those on the NANB virus and the inborn error of metabolism, and that the pathological diagnosis should be more comprehensive, implicating the etiology, the nodular size and the necroinflammatory activity.

Recently there has been remarkable improvement in the treatment of chondrosarcoma, accompanied with the development of diagnostic tools, operative technique, replacement materials and designs, anticancer-chemotherapy and radiotherapy. In well-deferentiated chondrosarcom, wide excision is the only treatment required. Nevertheless, in dedifferentiated chondrosarcoma, anticancerchemotherapy or radiotherapy is usually recommended after the wide excision. From 1984 to 1994, 22 patients diagnosed as chondrosarcoma had been treated at Seoul National University Hospital. We analysed anatomic distributions, size, methods of treatment and their results. The avereage age was 38 years and 10 months(15 years 73 years) and the average follow-up period was 3 years and 10 months(1 year and 6 months

Fisting is an uncommon sexual activity, and death due to fisting is very rare. In the present report, we describe a case of a woman who died from fisting by her male partner. A 38-year-old woman went to a motel with a man after consuming alcohol, and there they kissed each other. As desired by woman, the man inserted his fingers into her vagina and anus, and later inserted his fist and forearm into her vagina and anus. After 20-30 minutes of fisting, the woman became unconscious and died. The autopsy confirmed the presence of perineal and vaginal lacerations with massive internal pelvic soft tissue injury with uterine artery rupture. A partial tear was noted at the rectosigmoid junction. The cause of death was hypovolemic shock due to uterine artery rupture. Following court trials, the assailant was sentenced to 4 years of imprisonment for the felony of inflicting bodily injury resulting in death.

BACKGROUND: Although palmoplantar epidermal cysts have long been associated with develop ment following implantation of an epidermal fragment as a result of a penetrating or blunt injury, the pathogenic mechanism is still not fully understood. Since 1987, many cases have been reported in which human papillomavirus(HPV) could be associated with palmoplantar epidermal cysts. OBJECTIVE: In this study, we evaluated the clinicopathological findings of palmoplantar epidermal cysts and investigated them for the presence of HPV in order to examine the role of HPV in the pathogenesis of this disorder in Korea. METHODS: The clinical, histological, immunohistochemical studies were performed on seven cases of plantar cysts, and two cases of palmar cysts. RESULTS: No previous trauma history was seen. Histopathologically, parakeratotic nuclei, or vacuolar strutures within the keratinous mass in the cyst cavity were found. However, we could not find intracytoplasirnic eosinophilic bodies in the wall, the cyst content, or the overlying epidermis. The dyskeratotic keratinocytes were observed in 3 cases. Papillomavirus common antigens were not detected by immunohissochemical staining. CONCLUSIONS: Palmoplantar epidermal cysts in Korea have some different histological features compared to those of HPV 60-associated cases in Japan and we could not detect the immunohistochemical evidence of HPV infection in our cases.

Ganglion is the most common soft tissue tumor which occurs mainly in hand, but it can also occur in any part of the extremity. It is not always necessary to excise the tumor because it seldom cause symptoms severe enough to take operation. We reviewed the patients with ganglion treated surgically. Exculding the cases which were operated under local anesthesia and Bakers cyst, 42 patients were treated surgically from 1983 to 1992. Females were 33, and males 9. Average age at the time of operation, was 40 years (16 to 67). All the cases were analysed retrospectively in terms of surgical indication, anatomical location, size, duration of symptoms, relationship between recurrence and size, and complication. The average duration of follow-up was 1 year 7 months, ranging from 1 year to 4 years. The causes of operation were, cosmetic problem in 6996 (29 cases); pain in 19% (8 cases); and both comesis and pain in 12% (5 cases). The locations were, wrist in 4696 (19 cases); knee 29% (12 cases); foot 12% (5 cases); hand 7% (3 cases); forearm 2% (1 case); ankle 2% (1 case); and elbow 296 (1 case). The size of mass was less than 2.5 cm in 30 cases (71%), and more than 2.5 cm in 12 (29%). (Total average of size was 2.4 cm)The average duration of symptoms were 28 months (1 month 15 years). The recurrence was found in 7 cases: 3 of them (10%) occurred among 30 cases the diameter of which was less than 2.5 cm, and other four (33%) occurred among 12 cases, larger than 2.5 cm. There were no other complications.

PURPOSE: Results of revision total knee arthroplasties (TKAs) have provided relatively lower success rates than that of primary TKAs. We tried to evaluate the results and related problems of revision TKAs. MATERIALS AND METHODS: 27 revision total knee arthroplasties were evaluated clinically and roentgenographically with the American Knee Society Clinical Rating System. RESULTS: Pain score, range of motion, and knee score of aseptic and septic failures increased postoperatively after revision TKAs. Success rates of revision TKAs were 68.4% (13/19) for aseptic failure and 62.5% (5/8) for septic failure. We observed 9 complications including deep infections, wound dehiscence and superficial infections, fractures, and limitation of motion. CONCLUSION: Notable improvements were achieved in most of revision TKAs. However, relatively lower rate of success and higher rate of complications of revision TKAs emphasizes the importance of surgical technique handling significant bone loss, aggressive measure for complicated cases, and rehabilitation.

After UV irradiation to mouse epidermis, autoradiography using H-thymidine was performed to study the effects of UV on scheduled and unschcdu ed DNA syntheses. The results can be summarized as follows. l. In case of UVB 100mJ/cm, heavily labeled cells (HLCs) representing scheduled DNA synthesis began to decrease immediately after UVB irradiai,ior and were significantly decreased after 24 hours, but then recovered after 48 hours. The ecovery was maintained from 72 hours, up to 7 days. Sparsely labeled cells (SLCs) repres inting unscheduled DNA synthesis were significantly increased from immediately after UV 3 irradiation and up to 6 hours later. Repair was present at 24 hours, and was maintained at 48 hours, 72 hours, and 7 day after irradiation. 2. In case of UVA, UVA 10J/cm did not affect DNA synthesis sign ficantly. But in cases of UVA 30J/cm and 50J/cm, HLCs began to decrease immediately after UVA irradiation and were significantly decreased for 24 hours. Recovery occured at 48 hours, and was maintained from 72 hours up to 7 days. SLCs were significently increased immediately after and up to 6 hours after UVB irradiation. Repair generally occurred after 24 hours, and was maintained at 48 hours, 72 hours, and 7 days after ir rad ation.

BACKGROUND: Urticaria pigmentosa(UP) is primarily a disease of children. There have been no clinical studies of UP in Korea. OBJECTIVE: This study was performed to find the clinical characteristics of UP in Korean child-hood patients. METHOD: Twenty-nine cases of urticaria pigmentosa confirmed clinically and histopathologically were analyzed. RESULTS: The maculopapular type was the most common with the usual age of onset before the age of 6 months, and the lesions tended to be distributed in the central portion of the body. Darier sign was positive in 92% of the patients(24/26). No systemic involvements were detected in any of the patients with minimal associated symptoms. Seven patients of the maculopapular type and one patient of the multiple nodular type followed up for more than 2 years showed a tendency to improve or clear by the age of 6 years. CONCLUSION: Neonatal or infantile-onset patients of UP in Korean pediatric population were considered to have a benign clinical course and to require no aggressive therapy.
