We present 9 cases of plexiform schwannoma examined at Severance hospital from January, 1980 to September, 1987. The predilection sites of plexiform schwannoma included head and neck including oral cavity. The mean age at the time of diagnosis was 32 years. The difference of sex ratio was not apparent. Histopathological findings revealed multiple round to oval nodules encapsulated by thin fibroconnective tissue with nuclear palisading and Verocay body in each nodule. There was mild to moderate cellular atypia in some area, but mitotic figure was not found. The Bielschowsky's silver stain did not demonstrate any axon within or outside of the nodule. The thin capsule was positive with reticulin stain.

We present an autopsy case of signet ring cell carcinoma of urinary bladder which underwent widespread metastsis through nearly entire organ. The patient, 45-year old male, suffered from hematuria, dysuria and flank pain for 6 months. Under the diagnosis of the signet ring cell carcinoma by the cystoscopic biopsy, radical cystectomy and ileocutaneous ureteral division were performed. But he died after 11-months after the diagnosis. The autopsy confirmed the widespread metastasis at the lung, kidney, adrenal gland, parathyroid gland, heart, stomach, ileum, spine, rib and meninges. The preveously resected urinary bladder discolosed the well defined fungating mass at the dome and anterio-lateral portion without apparent evidence of the remnant of the urachus. Histologically, the signet ring cells were predominent and focally mucinous pool floating the signet ring cells was noted. We could find several foci of the well differentiated adenocarcinoma and poorly differentiated adenocarcinomas. The above findings may reflect that the origin of carcinoma may be from the multipotential transitional cell epithelium.

We investigated the overall survival rate after pulmonary metastasectomy in the bone and soft tissue sarcoma and the available prognostic factors related with the survival rate after pulmonary metastasectomy. Between 1986 and 1995, 9 patients (median age 32) with bone and soft tissue sarcoma with pulmonary metastasis were managed in the Catholic University of Korea. Until the final follow-up in May 1996, 6 patients have died of disease and their mean survival period was 28 months (9- 58months). The actual 5-year survival rate by Kaplan-Meier method was 33%. Prognostic factors such as tumor free interval, number of metastatic lesion, postoperative chemotherapy and histologic grade were analyzed. Three patients who had the tumor free interval over 3 years were alive (mean survival period: 52.6 months), whereas six patients who had the tumor free interval less than 3 years were dead (mean survival period: 19 months). Out of four patients with low grade tumor, three patients were alive with average 39.2 months survival period, whereas five patients with high grade tumor were all dead with average 19.2 months survival period. These results suggested that pulmonary metastasectomy in bone and soft tissue sarcoma may prolong the survival rate. The long tumor free interval, histological low grade and soft tissue sarcoma may influenced on prolonged survival rate. However, number of metastatic lesion or postoperative chemotherapy has not influenced on the survival rate.

We report a case of primary cardiac angiosarcoma in a 35 year-old woman. She presented with dyspnea, facial edema and neck vein distension during 1 month. The oval round large mass(8x4 cm) filling the right atrium infiltrated into the entire thickness of the lateral wall and extended to the vena cava and ventricle. The interatrial septum and pericardium seemed to be intact. Despite the surgical excision and adjuvant chemo-and radiotherapy, the patient died 8 months later due to tumor recurrence. The histologic findings of tumor varied from benign looking capillary proliferation mimicking granulation tissue to sarcoma composed of spindle cells. But anastomosing vascular channels lined by anaplastic polygonal cells and intracytoplasmic lumen containing red blood cells were characteristic findings. These tumor cells showed positive reaction to endothelial cell antigen and factor VIII-related antigen. The intercellular junctional complex and vascular channels formed by cytoplasmic process of tumor cells were identified by the ultrastructural study.

BACKGROUND: It has been reported that hypercholesterolemia is associated with coronary heart disease and that alcohol intake has influence on the lipid metabolism. This study was conducted to evaluate the relations between alcohol intake and serum lipid level. METHODS: We reviewed 906 subjects who had visited for routine checkup at family practice of Hanil hospital and then excluded 130 subjects with DM, renal disease, thyroid disease, hepatic disease or drug administration which might have influence on serum lipids. From the remaining 776 subjects, we obtained the amount and the frequency of alcohol drinking during the previous 2 weeks and the duration of alcohol intake, using a formed questionnaire. The alcohol dependence score was recorded by the National Alcoholism Screening Test. The serum lipids such as total cholesterol, triglyceride, and HDL-cholesterol were tested by enzyme method and the obesity index was obtained by Broca's method. These data were analyzed by SAS/PC program RESULTS: The total number of subjects was 776. Of those, 67.7%(n=525) were male and 32.3%(n= 251) females. The mean age of subjects was 50.5 years(range 15 to 77 years). The distribution according to the obesity index was as follows ; underweight group 7.1%, normal-weight group 38.1%, overweight group 31.6%, obesity group 23.2%. The number of the drinkers was 382(49.2%) in males and 7 (0.9%) in females. The mean serum lipid level were compared and analyzed among the groups. The results were as follows ; the total cholesterol and triglyceride levels were higher in males and the HDL-cholesterol levels was higher in female. The total cholesterol and triglyceride levels increased with age and obesity index, the HDL-cholesterol level decreased with obesity index. In the relationship between alcohol intake and serum lipid levels in males, the geometric mean of triglyceride level was higher among all the variables of alcohol intake, and that of HDL-cholesterol level increased with the amount and the frequency of alcohol intake. The results of multiple regression analysis associated with age, obesity index, the amount and the frequency of alcohol intake in males were as follows ; the triglyceride level was positively associated with the amount of alcohol intake, and the HDL-cholesterol level was positively associated with the frequency of akohol intake. CONCLUSIONS: The effects of age, sex and the obesity index on the serum lipid level are remarkable, and in males, alcohol intake increases triglycaride and HDL-cholesterol levels. Further study is needed to find out about whether alcohol intake have influences on coronary heart disease according to serum lipid levels.

Radiological investigation in patients with clonorchiasis is very important as this is the only method of evaluating the severity of clonorchiasis. In order to correlate the radiologic and pathologic findings of clonorchiasis, fourteen rabbits infested with Clonorchis sinensis and five control rabbits were examined radiologically by ultrasonography, computed tomography and cholangiography and the results were correlated with pathologic findings. Dilatation of the intrahepatic small bile ducts of the liver was due to obstruction by flukes: oval or elliptical small filling defects or irregular margin of the bile ducts on cholangiogram or intraluminal echoes on sonogram represented flukes per se; periductal thickening on sonogram and periductal enhancement of bile ducts on CT were due to inflammatory cell infiltration, adenomatous hyperplasia and periductal fibrosis: band like enhancement at the periphery of the liver on CT represented proliferated bile ducts, destruction of liver cells and resultant fibrosis. The study confirmed the pathological bases for the radiological findings of clonorchiasis in liver and bile ducts and will, perhaps, serve as a basis for the future radiologic-pathological correlation of clonorchiasis and in further clinical and experimental researches in the biliary tract diseases.

We report a 33-year-old woman with a 1-year history of typical skin features of dermatomyositis without any evidence of muscle involvement. Her skin eruption of the face (heliotrope erythema) and hands (Gottron's papules) and skin biopsy findings were typical of dermatomyositis. Levels of serum muscle enzymes were within normal ranges and electromyography showed no signs of muscle involvement. During a 1-year follow-up, she had no signs of muscle weakness. Based on these clinical and laboratory findings, our case can be diagnosed as amyopathic dermatomyositis.
