Association of the hepatoid and choriocarcinomatous components in adenocarcinoma of the stomach is extremely unusual and raises a possibility of new approach understand the histogenesis of gastric hepatoid adenocarcinoma. This paper describes a Borrmann type III adenocarcinoma of the stomach with both choriocarcinomatous and hepatoid components in composite tumor pattern in a 50-year-old man. Tubular arrangement of differentiated embryonalcarcinoma was encountered in choricarcinomatous and hepatoid areas, which showed strong immunoreactivity to beta-HCG and AFP, respectively. The findings suggest that gastric adenocarcinoma may have a potential of differentiation toward embryonal carcinoma. from which both choriocarcinoma and hepatoid variant of gastric adenocarcinoma may develop by retrodifferentiation.

A computer program using automatic coding of the diagnosis has been used for report printing as well as data storage and retrieval system at the Department of Pathology, Seoul National University Hospital. Previous surgical pathology files were also computerized by the automatic coding system using personal computer, and 100,000 cases of surgical pathology data during 7 years were computerized at present. The cpmputerized surgical files were counted and listed according to topograph and morphologic diagnosis. It is available to print out the list of a specific diagnosis or to copy the records to a floppy diskette. Collection of cases in surgical pathology files using cpmputerized automatic coding system becomes much convenient and accurate than using stored file cards or log books. In addition, previous biopsy records of the patient are automatically searched during the routine work so that understanding of a patient as a whole is possible through the informations about previous pathologic diagnosis. We confirm that automatic coding methods is the most practical and economic method for computerization of the surgical pathology records.

PURPOSE: To evaluate the spatial distribution of various proton metabolites in the human brain with use of water-suppressed in vivo 1H MR spectroscopic imaging (MRSI) technique MATERIALS AND METHODS: All of water-suppressed in vivo 1H MRSI were performed on 1.5 T whole-body MRI/MRS system using Stimulated Echo Acquisition Method (STEAM) Chemical shift Imaging (CSI) pulse sequence. T1 -weighted MR images were used for CSl Field Of View (FOV; 24 cm). Voxel size of 1.S cm3 was designated from the periphery of the brain which was divided by 1024 x 16 x 16data points. RESULTS: Metabolite images of N-acetylaspartate (NAA), creatine/phosphocreatine (Cr) + choline/phosphocholine (Cho), and complex of gamma-aminobutyric acid (GABA) -I- glutamate (Glu) were obtained on the human brain. CONCLUSION: Our preliminary study suggests that in vivo 1H MRSl could provide the metabolite imaging to compensate for hypermetabolism on Positron Emission Tomography (PET) scans on the basis of the metabolic informations on brain tissues. The unique ability of in vivo 1H MRSI to offer noninvasive informations about tissue biochemistry in disease states will stimulate on clinical research and disease diagnosis.

Eight cases of combine hepatocellular-cholangiocarcinoma(HCC-CC) of the liver were analysed along with their growth patterns and histologic subtypes to draw a possible implication in understanding of their histogenesis. The relative incidence of combined HCC-CC among the surgically resected primary carcinomas of the liver(485 cases) was 1.6%. The combination patterns varied and were classified as follows; the multinodular tumor, each consisting of HCC or CC element(type 1) was found in 1 case, the single tumor mass with two distinct compartments of HCC and CC(type 2) in 3, and the single tumor with random mixture of two elements(type 3) comprised the remaining 4 cases. Of the 7 cases of single tumor mass(type 2 and 3) HCC and CC comprised the major component in 5 and 2 cases, respectively. The histologic features of both HCC and CC elements were not different from those of isolated HCC and CC, except for two of CC element in type 3 which disclosed the intermediated differentiation or socalled cholangiolocellular carcinoma in part. We conclude that there is no significant difference in the relative incidence of combined HCC-CC among primary carcinomas of the liver and their subtypes compared to that in other countries, regardless of high incidence of both HCC and CC in Korea. Also, we discussed a possible histogenisis along a hypothesis that some of the combined HCC-CC be the consequence of interposition of different cell type from a new subclone into the growth of an initial single cell type of primary carcinoma of the liver.

In the neonatal diseases of pediatric surgery, a congenital duodenal obstruction is an important part of congenital disease. Between March 1994 and December 1996, 15 cases of congenital duodenal obstruction were experienced and treated at St. Francisco's General Hospital. The following results were obstained: 1) The types of congenital duodenal obstruction were 5 malrotations, 4 atresia, 3 webs, 2 annular pancreases, and 1 obstruction due to an ectopic pancreas. 2) There were 8 males and 7 females; the male to female ratio was 1.14 : 1. 3) The age on admission was 1 to 7 days in 13 cases (87%), and all cases were admitted within 1 month after birth. 4) The birth weight below 2500 gm in only 2 cases (13%). 5) The main clinical symtom was vomiting (93%). 6) Associated anomalies were found in 11 cases (73.3%): 4 cases of congenital heart disease, 3 of Down's syndrom, 2 of malrotations, 2 of urogenital anmalies, and 1 each of jejunal atresia, midgut volvulus, and polydactyly. 7) Postoperative complications occurred in 4 cases (27%), but there was no deaths.
