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.

Transfollicular extrusion of sebaceous gland lobules was observed in a case of actinic keratosis and 2 cases of sebaceous hyperplasia. The patient of act.inic keratosis was a 44-year-old white man and the patients of sebaceous hvperplasia were a i3-year-old Korean girl and a 28-year-old Korean man. The sebaceous gland lobules located within the dilated infundibular area and partly between separated granular layers were intact and partly surrounded by keratin materjal. No histopathologic overlapping of sebaceous gland lobules was observed. We suppose that transfollicular ext,rusion of sebaceous gland lobules may not be artifact. but one of natural phenomena. But further study will be necessary to evaluate the significance of this peculiar histopathologic findings.

The long-term studies of total knee arthroplasty (TKA) have confirmed reliable relief of pain and maintenance of function. However there have been few generalized studies of factors influencing the results of TKA. We evaluated retrospectively 187 TKAs (137 patients) which had been performed between January 1987 and May 1995. The follow-up period was from one year to eight years (mean, 3 years and 8 months). There were 133 knees of osteoarthritis (OA), 43 knees of rheumatoid arthritis (RA) and 11 knees of other causes including septic knee sequelae. We considered the preoperative factors as age, sex, side (right or left), body weight, height, primary disease, flexion contracture (FC), further flexion (FF), range of motion (ROM) of joint, deformity of varus and valgus and pain score, muscle strength score, instability score, total knee score according to the knee rating scale of the Hospital for Special Surgery (HSS). We considered the clinical results as FC, FF, ROM, pain, muscle strength, instability, total knee score according to the knee rating scale of the HSS and the radiological results as Roentgenographic Evaluation and Scoring System of American Knee Society and radiolucent line more than 2mm in width. We evaluated the clinical and radiological results of TKAs followed up more than I year and analyzed the results based on above factors. The results were as follows: 1. The preoperative factors influencing final FC were not the primary disease and FC, but the FF and ROM. The preoperative factors influencing final FF and ROM were the primary disease, the FF and ROM. 2. The pain, muscle power, instability scores were improved but there was no significant factor influencing them. The HSS knee scores were higher in OA group than RA group postoperatively. 3. There was no preoperative factor influencing the complication, revision, the radiological results. The preoperative factors influencing the results of TKA were the FF, ROM and the primary disease.

Dermatofibrosarcoma protuberans(DFSP) is an uncommon recurrent soft-tumor of skin and is locally highly invasive and aggressive, although it rarely metastasizes. When possible, of the many treatment modalities, the surgical excision is indicated primarily. There are three surgical modalities, which are excision with undefined or conservative surgical margins, excision with wide surgical margins and Mohs micrographic surgery(MMS). And the classical standard surgery was the local wide excision with at least 3cm margin around the primary tumor and through the deep fascia. However recent studies has showed that MMS decreased the recurrent rate of the tumor, conserving the normal uninvolved tissue, and MMS is accepted as the first choice treatment modality of DFSP. Some studies reported that the margin of 2.5cm is necessary to clear the tumor in MMS. We present two cases of recurrent DFSP treated by Mohs micrographic surgery, one through 4-staged resection, the other, 3-staged resection of the tumor.

Agenesis of the right lobe of the liver is a rare anomaly which may be associated with stone diseases, portal hypertension, and other congenital anomalies. The radiological differential diagnosis includes lobar atrophy due to cirrhosis or hilar cholangiocarcinoma. We present a case of agenesis of the right lobe of the liver with characteristic clinical and radiological findings.

OBJECTIVE: We studied to determine the effect of blood or meconium contamination on the TDx-FLM assay for the assessment of fetal lung maturity. We also studied to evaluate the degree of diluted contaminants that affect the results. METHODS: Nineteen samples of amnotic fluid-14 cases < GA 37weeks and 5 cases > GA 37weeks-were collected and assayed for assessment of fetal lung maturity using tbe TDx-FLM assay. Among the above 19 samples, we used 12 samples-7 cases < GA 37weeks and 5 cases > GA37 weeks-to contaminate with blood or meconium. Maternal blood was added to the amniotic fluid at increasing concentrations fro 1:10 to 1:1280. Diluted meconium (0.5g meconium/10ml amniotic fluid) was added at increasing concentration fiom 1:1 to 1:128. Each samples were assessed by TDx assay. RESULTS: TDx values in the cases of gestational age 37 weeks or more were matured level or borderline level(TDx value > 50mg/g), but below 37 weeks, TDx values wae immature level(TDx value < 50mg/g) except one case. In preterm cases, blood or meconium contamination did not affect the TDx values significantly, although the thick meamium contamination (diluted meconium: amniotic fluid 1:1 - 1:4) increased the TDx values. In term cases, they did not affect the TDx values. CONCLUSION: TDx test was suitable for the evaluation of fetal lung maturity regardless of blood or meconium contamination.
