Dermoid cysts of the posterior fossa are benign, mostly midline, congenital brain neopasm, usually located above or behind the vermis or adjacent meninges2)18)20), Dermoid lesions are slow growing and may become quite large before producing signs and symptoms12). We have recently experienced a case of dermoid which arised in cerebellar hemisphere. A 32-year old woman who had a history of chronic headache at morining was visited in our department and she was also complained of a egg-sized plapable mass which was growing nature, non-tender, soft, and movable on the right occipital area. On admission, there were no specific localizing and lateralizing neurological abnormalities. Unenhanced CT scan shows hypodense mass in the left cerebellar hemisphere and cystic mass at the right occipital scalp(Fig. 1. A). T1-weighted MR image shows hypointense mass in the left cerebellar hemisphere(Fig. 2. A). The Carotid angiography shows non-specific findings. Paramedian suboccipital approach was performed and mass was removed from the lleft cerebellar hemisphere. The cystic scalp mass was removed totally from the left cerebellar hemisphere. The cystic scalp mass was removed totally from the right occipital area. Diagnosis of dermoid cyst was confirmed pathologically by the specimens obtained from two different sites, left cerebellar hemisphere and right occipital ccalp.

OBJECTIVE: The clinical value of preoperative serum squamous cell carcinoma antigen(SCC) in relation to clinical stage, tumor volume, disease extent and prognosis has already reported in many papers. The aim of this study is to analyse the relationship between preoperative SCC level and pelvic lymph node metastasis. Matrials and METHODS: From March 1995 to December 1998, 157 patients who examined pretreatment SCC levels before undergoing radical hysterectomy for squamous cell carcinoma of uterine cervix were included. The effect of pelvic lymph node status on the SCC level was examined by comparing 125 cases with cancer limited uterus or upper vagina and 32 cases with cancer confined to the uterus (including upper vagina) and pelvic lymph node using multivariate analysis. RESULTS: 90% of patients without pelvic lymph node metastasis showed SCC levels of 2.9ng/ml or below. 60.7% of patients with serum SCC level more than 2.9ng/ml exhibited pelvic lymph node metastasis. The marker values exceeding 2.9ng/ml increased risk of nodal metastasis 5 times compared with serum level 2.9ng/ml or below. Multivariate analysis confirmed that the pelvic lymph node metastasis had a large impact on the marker level than did tumor size or depth of stromal infilteration. CONCLUSION: SCC levels greater than 2.9ng/ml can be considered a high risk zone for nodal metastasis

Teratomas are neoplasm composed of a wide variety of tissues foreign to the organs or anatomic sites in which they arise. They generally arise in gonads but a few cases are described in extragonadal sites, such as sacro-coccygeal region, mediastinum, neck, and retroperitoneum. Most sacrococcygeal teratomas are encountered in infants, particularly in neonates, and a primary sacrococcygeal teratoma is a extremely rare neoplasm in adults. Recently, we experienced two cases of presacral teratomas arising in adult, therefore we present these cases with a brief review of the literatures

The purpose of this study was to determine the frequency of chromosomal or genetic causes of primary amenorrhea, and was made to assess the etiology of disorders in those patients whose chromosome appeared normal. Sixty eight patients with primary amenorrhea were evaluated clinically and cytogenetically, which were refered to our Cytogenetic Laboratory in Department of Obstetrics and Gynecology, Pusan National University Hospital, from Aug. 1988 to Dec. 1996. The results were as follows. l. Out of 68 cases with primary amenorrhea, 40 cases (58.9%) had the normal chromosome constitutions and 28 cases (41.1%) had the abnormal chromosome constitutions including 46, XY. 2. Turner's syndrome was found in 25 cases (36.7%), consisting of 11 cases (16.1%) of 45, X, 3 cases (4.3%) of 46, X, i (Xq), 1 case (1.5%) of 46, X, inv (X), 1 case (1.5%) of 46, X, del (Xq), 1 case (1.5%) of 46, X, del (Xp), 1 case (1.5%) of 46, X, tel (Xq), 1 case (1.5%) of 45, X/46, XX, 1 case (1.5%) of 45, X/46, XY, 1 case (1.5%) of 45, X/47, XXX, 2 cases (2.9%) of 45, X/46, X, del (Xq), I case (1.5%) of 45, X/46, X, del (Xq), 1 case (1.5%) of 45, X/46, X, r (X). 3. 3 cases (4.3%) had the 46, XY chromosome constitution consisting of 2 cases (2.9%) of testicular feminization syndrome and 1 case (1.5%) of pure gonadal dysgenesis. 4. Among 40 patients whose chromosome are normal, the etiologies of amenorrhea were assumed to be caused by 11 cases (27.5%) of hypogonadotropic hypogonadism (idiopathic), 10 cases (25.0%) of congenital absence of vagina, 5 cases (12.5%) of pure gonadal dysgenesis in order of frequency.

Balloon pulnounary valvuloplasty is an established method in the treatment of congenital valvular pulmonary stenosis. Balloon valvuloplasty was performed by using one or two balloons in a total of 19 mongrel dogs. Cross sectional area ratio ranging 145-406% was used to compare the relative sizes of the pulmonary annulus the balloon Hemodynamic changes and cardiac damages in single and double balloon groups were analyzed. Survival time of double balloon group was longer than that of single balloon group(P<0.05). Increment of the right ven?dular systolic pressure in single balloon group (mean 38 mmHg) was greater than that in double balloon group (mean 18 mmHg) (p<0.05). Decrement of the femoral arterial pressure in single balloon group (mean 87 mmHg) was greater than in double balloon group (mean 41 mmHg) (p<0.05). The locations of trauma were mainly the right ventricular free wall, the main pulmonary artery, the anterior leaflet of the pulmonary valve and in a less degree, anterior wall of the right atrium, the right ventricular outflow tract and the left pulmonary artery in the order of frequency. There were no significant differences in cardiac damages between single and double balloon groups (P>0.05). Major microscopic findings were sloughing of the endotheliu, fibrin deposition, hemorrhage, localized myocardial infarction and so on. In conclusion, double balloon pulmonary valvuloplasty is superior to single balloon technique in survival time and hemodynamics. Therefore, double, balloon technique is recommended for the pulmonary valvuloplasty.

OBJECTIVE: The purpose of this study was to evaluate the therapeutic efficacy and toxicity of high dose cisplatin-cyclophosphamide combination chemotherapy on patients with primary epithelial ovarian cancer. METHODS: A review of 63 patients previously diagnosed as primary epithelial ovarian cancer after initial operation and histology at Pusan National University Hospital from Jul. 1993 to Jun, 1997 was performed. Patients were received the combination chemotherapy including cisplatin 100mg/m2/day and cyclophosphamide 750mg/m2/day, repeated 6 cycles every 4 weeks. The mean age was 48 years old, and previous surgical procedures were total abdominal hysterectomy and bilateral salpingo-oophorectomy with omentectomy. The patients were classified into FIGO stage and pathologic results. RESULTS: The clinical response rate was 100% in the FIGO stage Ic patients with PC combination chemotherapy, 100% in stage II, 53.5% in stage III, and 25% in stage IV. The overall response rate was 69.8%. The 3-year survival rate according to the treatment groups was 93.3% in stage Ic group, 60% in stage II, 50% in stage III and 0% in stage IV. The mean survival duration was 34.6 months. Hematologic toxicities in cisplatin-cyclophosphamide chemotherapy were neutropenia and anemia. Nausea and vomiting were the most common side effects and occurred in 96.8%. Most of the toxicities were grade 1 and 2. CONCLUSION: The combination chemotherapy with cisplatin-cyclophosphamide is relatively safe and effective method in the treatment of primary epithelial ovarian cancer.
