Clear cell sarcoma of tendon and aponeurosis is a rare malignant tumor. It occurs chiefly in young adults, predominates in women and is most common in the regions of the foot and ankle. We report a case of clear cell sarcoma of tendon and aponeurosis in s 22-year-old man. he pstient had had a asymptomatic, normal skin colored, relativerly hard, dome shsped nodule on the anterior chest for 6 months. Histopsthologic findings revealed uniform pattern composed of compact nests of round or fusiform cells which had clear cytoplasm and were surrounded by delicate framework of fibrocollagenous tissue, and the individual tumor cell had a fairly regular appearance of possessing round to avoid vesicular nucleus with prominent basophilic nucleolus. One year after surgical excision and post operative radiotherapy, there was no recurrence.

PURPOSE: To evaluate the usefulness of spiral CT in predicting the depth of tumor invasion in patients with gastric cancer by comparing with histopathological finding. MATERIALS AND METHODS: We studied spiral CT scans of forty-eight patients, in whom gastric cancer was proven by gastrofibroscopic biopsy and surgery. After distending the stomach with 400ml tap water or effervescent granules, 100ml of contrast media was given intravenously at a rate of 3ml/sec. CT scanning was started at 45 sec after administration of the contrast material. Gastric tumors were subdivided into five types according to enhancing pattern from the inner layer of gastric wall to the outer layer. These pattern were correlated with histopathologic results. RESULT: The tumor masses were detected on CT scan in 10(77%) of 13 patients with early gastric cancer, while, the tumor masses were seen on CT scan in all patients with advanced gastric cancer. Of 9 patients with type 1 or type 2 enhancing pattern, early gastric cancer(T1) were proven in 7 patients(78%), serosal invasion (T3) in 2 patients(22%). In contrast, among 29 patients with type 4 and type 5, 22 patients(76%) were proven as serosal invasion(T3). Of 7 patients with type 3, 3 patients(43%) were proven as serosal invasion(T3), three(43%) as subserosal invasion(T2), one as early gastric cancer(T1). CONCLUSION: Analysis of morphological enhancing pattern on spiral CT is useful in predicting the depth of tumor invasion in patients with gastric cancer.

PURPOSE: To evaluate the NT in the first trimester associated with fetal chromosomal abnormality, fetal structural abnormality and adverse pregnancy outcome. METHODS: From Mar. 1993 to Dec. 1997, 133 cases of increased NT were reviewed retrospectively. All these fetues were taken a karyotyping and/or a high resolution ultrasonography for associated anomaly. The NT was measured by transvaginal ultrasonography(TVS) and transabdominal ultrasonography(TAS) if difficulty was encountered with TVS in the period of the 10th-14th week of gestation. The increased NT is approved when it is over 3mm. RESULTS: Of these 133 cases, 102 cases(76.7%) revealed normal outcomes and 31 cases(23.3%) revealed abnormal outcomes such as chromosomal abnormality, structural abnormality and adverse pregnancy outcome, The mean value of NT was 3.44+/-0.68mm in the normal group and 4.93+/-2.70mm in the abnormal group, respectively. The chromosomal abnormalities were found in 16 of the 31 cases: nine Down SD, two Patau syndrome, one Tuner synrome, one triploidy, one 46, XX,i(18q), one 47,iso(Xp)/46,XX one confined placental mosaicism. In 12 cases of the 31 cases, the structural anomalies were detected. Of these 12 cases, 3 cases were eventually developed to cytsic hygroma, 3 cases were cardiac anomaly, 3 cases were renal anomaly, 1 case was congenital diaphragmatic hernia, 1 case was skeletal dysplasia and 1 case was suspected syndrome. The adverse pregnancy outcome such as intrauterine growth restriction, intrauterine fetal death and preterm labor was revealed in 3 cases. In the cases of NT over 7mm, the result was 100% abnormal outcome. CONCLUSION: Increased NT in the first trimester could be a highly efficient the predictor for detection of chromosomal abnormality, structural anomaly and adverse pregnancy outcome.

Laser riidectomy with combined application of the Argon and the Nd-YAG laser was performed on 25 eyes of 24 patients with primary narrow angle glaucoma(19 eyes) or pupillary block glaucoma(6 eyes). Patients were followed for from a minimum of one month to maximum of six months and were evaluated the postoperative intraocular pressure, the iridectomy patency, the number of burst and the postoperative complication. In our study, the results obtained are as follows: 1. Pantency rates of iridectomy site were 100%. 2. Postoperative intraocular pressure were well controlled except one eye. 3. Numbers of burst were obviously decreased. 4. The bleeding during the iridectomy was noted in one eye(4%). 5. Immediate postoperative intraocular pressure elevation was seen in one eye(4%).
