Sex cord tumor with annular tubules (SCTAT) is a rare ovarian neoplasm which usually occurs in two forms. In patients associated with Peutz-Jeghers syndrome, the tumors are usually small, bilateral or multifocal, and show benign clinical course. However, tumors from patients without the syndrome are often large, usually unilateral, and rarely show malignant behavior. Serous surface papillary carcinoma (SSPC) is an aggressive neoplasm which involves peritoneal linings, including ovarian surface. Recently, we encountered a case of an unusual combination of SCTAT and SSPC in the ovary of a 55-year-old Korean woman presented with abdominal distention for one year. Systemic review and physical examination were within normal limit, except for abdominal discomfort and distention. There was no stigmata of Peutz-Jeghers syndrome in all diagnostic examinations, including gastroscopy and colonoscopy. Pelvic computed tomography showed adnexal mass with multiple peritoneal nodules. Exploration revealed uterine and ovarian surfaces covered with multiple, yellow-white papillary nodules. However, the sizes of both ovaries were within normal limit. Typical serous papillary carcinomas were identified in nodules from peritoneum and ovarian surfaces. Well-circumscribed columnar epithelial cell nests composed of ring-shaped tubules encircling hyalinized basement membrane-like materials were found in the ovary away from serous surface papillary carcinoma.

Unilateral renal agenesis is uncommon congenital condition with important implication when operation is performed. We report on two cases of unilateral renal agenesis but blind loop of ureter in a 2 year male child with vesical diverticulum and a 8 year old girl with contralateral hydronephrosis. An excretory urogram of the former revealed nonvisualization of left kidney and normal right kidney, it of the latter showed marked hydronephrosis of right kidney and nonvisualization of left kidney. These cases were finally confirmed by exploratory surgery with transvesical retrograde pyelography and histopathological findings of resected surgical specimen.

A retrospective analysis of 108 patients who had undergone transurethral prostatectomy for benign prostatic hyperplasia between January 1988 and December 1992 was performed to evaluate risk factors influencing intraoperative and postoperative morbidity and mortality. Of 108 patients complications occurred in 32 cases, with the morbidity rate of 29.6% but no death occurred. The most common postoperative complication was bleeding in 9 cases(8.3%) followed by incontinence in 7 cases(6.5%), capsular perforation in 4 cases(3.7%), failure to void in 4 cases(3.7%) and urethral stricture in 4 cases(3.7%). Risk factors which increased the morbidity of transurethral prostatectomy were age greater than 75 years and the presence of associated medical disease(p<0.05) but a resection time of more than 90 minutes, weight of resected tissue more than 30 gram and amounts of irrigating solution of more than 20 L did not increase the postoperative morbidity significantly. In conclusion, meticulous preoperative and postoperative cares are necessary because poor general condition increase the postoperative complications and long-term, prospective randomized studies are required to evaluate risk factors influencing postoperative morbidity after transurethral prostatectomy.

Focal nodular hyperplasia (FNH) is a rare, benign hepatic tumor which was usually discovered incidentally by imaging procedure performed for some other reasons. FNH is typically asymptomatic and, it seldom bleeds. There is no evidence to support any relation with primary liver cancer. Accordingly, the preferred management is conservative, and excision is reserved for large symptomatic and complicated lesion, or when the diagnosis remains uncertain. Although many cases of FNH has been described to date in the other countries, only four cases of FNH has been reported in Korean literature. In the present report we describe a 7 cm sized asymptomatic lesion of FNH in a 23-year-old woman, that was disclosed by various kinds of imaging procedure. The left lateral segmentectomy was performed. The mass was firm and showed areas of localized growth of mature hepatocytes and septal fibrosis accompanied with marginal ductal proliferation, consistent with FNH. It also displayed an incomplete stellate architectual configration consisted of a central fibrous scar.

PURPOSE: The aim of this pilot study was to investigate the effect of etched microgrooves on the hydrophilicity of Ti and osteoblast responses. MATERIAL AND METHODS: Microgrooves were applied on Ti to have 15 and 60 micrometer width, and 3.5 and 10 micrometer depth by photolithography, respectively. Further acid etching was applied to create Ti surfaces with etched microgrooves. Both smooth- and acid-etched Ti were used as the controls. The hydrophilicity of Ti was analyzed by determining contact angles. Cell proliferation and osteogenic activity of MC3T3 mouse preosteoblasts were analyzed by bromodeoxyuridine assay and alkaline phosphatase (ALP) activity test, respectively. One-way ANOVA, Pearson's correlation analysis and multiple regression analysis were used for statistics. RESULTS: Etched microgrooves significantly increased the hydrophilicity of Ti compared to the smooth Ti. 60 micrometer-wide etched microgrooves significantly enhanced cell proliferation, whereas the osteogenic activity showed statistically non-significant differences between groups. Result of the osteogenic activity significantly correlated with those of hydrophilicity and cell proliferation. Hydrophilicity was determined to be an influential factor on osteogenic activity. CONCLUSION: This study indicates that increase in hydrophilicity of Ti caused by etched microgrooves acts as an influential factor on osteogenic activity. However, statistically non-significant increase in the ALP activity suggests further investigation.

We present a case of systemic lupus erythematosus(SLE) asseci ted with vitiligo in a 57 year-old male patient. Physical examination revealed two distinct skin lesions those of itiligo showed as centrally located depigmented patches surrounded by erythernatous patch on the right cheek, scalp and left dorsurn of hand and those of SLE showed as erythematous papules and patchs with partial adherent scales on the face, scalp, neck, both extensor surface of arm, and left dorsun of hand. Their coexistence lends credence to the contention that altered autoimrnunity may play a role in the pathogenesis of each of these diseases. In Western countries and Japen, patients with lupus erythema osis have been observed to develop vitiligo or depigmented spots on the skin, while in Korea, its has not been previously observed.
