From Jan. of 1990 to Dec. of 1992, we have experienced three cases of multiple primary malignant neoplasms originated from different histogenesis, in the Department of Orthopedic Surgery of Korea Cancer Center Hospital. Liposarcomas, malignant fibrous histiocytoma were combined with renal cell carcinoma, mucinous cystadenocarcinoma of ovary or prostatic cancer. With Moertel's classification, synchronous tumors were found in 2 cases and metachronous in 1 case. Synchronous tumors were 2 liposarcomas-renal cell carcinoma or mucinous cystadenocarcinoma of ovary. Metachronous tumors were malignant fibrous histiocytoma-prostate cancer. We couldn t find any family history among them. The causes of these multiple malignancies were considered as the individual predilrection to tumors.

Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. This condition is characterized by the absence or rudimentary development of fetal heart, and associated with various anomaly. The presence of an acardiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. The principal perinatal problems associated with acardiac twinning are pump-twin congestive heart failure, maternal hydramnios, and preterm delivery. We recently experienced a case of acardius anceps associated with a normal male infant, so present with a brief review of the literature.

Discoid meniscus in the knee joint is common. From July 1990 through June 1994, the authors performed arthroscopy on 968 symptomatic knee joints. One hundred and six knees of 102 patients had discoid meniscus. Of the 106 knees, 14(13.2%) cases were associated with other intraarticular anatomic variants. There were 7(6.6%) cases with anomalous insertion of the anterior horn of the medial meniscus into the anterior cruciate ligament, and 7(6.6%) cases with anterior transposition of the insertion of the anterior cruciate ligament below the anterior tibial margin like the insertion of the posterior cruciate ligament. Of the 14 patients, the discoid meniscus were reshaped in 11 knees, partially resected in 2 knees, and one patient was treated with repair of a peripheral tear and reshaping. But had no treatment in associated intraarticular anatomic variants. The follow up was done from 24 to 54 months(average 37 months) after surgery. The results were excellent in 8 knees ; good in 4 knees and fair in 2 knees(Ikeuchi scale, 1982) The patients with excellent or good results were satisfied as were the authors, and these anatomical variants other than the discoid meniscus were not related to the patient's symptoms.

The combination of the various diagnostic methods of palpable breast mass has improved the diagnosticaccuracy. From Sep.1983 to Aug. 1985 pathologically proven 85 patients with palpable breast masses examined withX-ray mammography, ultrasonography, penumomammography and aspiration cytology at Korea Cancer Center Hospital wereanalyzed. The diagnostic accuracies of each methods were 77.6% of mammogram, 74.1% of ultrasonomgram, 90.5% ofpenumommaogram and 92.4% of aspiration cytology. Pneumommamograms was accomplished without difficulty orcomplication and depicted more clearly delineated mass with various pathognomonic findings; air-ductal pattern infibroadenoma(90.4%) and cystosarcoma phylloides(100%), air-halo in fibrocystic disease(14.2%), fibroadenoma(100%),cystosarcoma phylloides (100%), air-cystogram in cystic type of fibrocystic disease(100%) and vaculoar pattern orirregular air collection without retained peripheral gas in carcinoma.

Congenital diaphragmatic eventration is an abnormal elevation of the diaphragm as a result of developmental failure of muscular fibers during the fetal period. Mediastinal shift to the contralateral side may cause significant compression of the affected chest contents resulting in compromised pulmonary function especially when bilaterally involved. The differentiation between congenital diaphragmatic eventration and diaphragmatic hemia is very difficult but eventration has a better perinatal outcome compared to diaphragmatic hernia. We report a case of congenital diaphragmatic eventration on left side with good perinatal outcome after plication in which the initial prenatal diagnosis of diaphragmatic hernia was made by prenatal ultrasonography.

We report a case of malignant tumor of the stomach showing both carcinoma and sarcoma components in a 47 year-old woman. The resected stomach revealed two tumors which were in different location. The one mass was a 2 x I cm, poorly demarcated tumor at the body, along the lesser curvature and the other was a 6 x 7 cm, well demarcated polypoid tumor with a central depression at cardia of the posterior stomach wall. The tumor at the body was a poorly differentiated adenocarcinoma which showed strong reactivity for CEA. The tumor at the cardia was composed of epithelioid or spindle shaped cells with abundant eosinophilic cytoplasm and revealed 5-6 mitoses per ten high power field. The tumor at the cardia was diagnosed as epithelioid leiomyosarcoma and showed reactivity for vimentin but none for actin, desmin,keratin, and CEA. This is different from the usual carcinosarcoma.

PURPOSE: We investigated the statistical methods to compose the functional brain map of human working memory and the principal factors that have an effect on the methods for localization. MATERIALS AND METHODS: Repeated PET scans with successive four tasks, which consist of one control and three different activation tasks, were performed on six right-handed normal volunteers for 2 minutes after bolus injections of 925 MBq H0 at the intervals of 30 minutes. Irnage data were analyzed using SPM96 (Statistical Parametric Mapping) imple-mented with Matlab (Mathworks Inc., U.S.A.). Images from the same subject were spatially registered and were normalized using linear and nonlinear transformation methods. Significant difference between control and each activation state was estimated at every voxel based on the general linear model. Differences of global counts were removed using analysis of covariance (ANCOVA) with global activity as covariate. Using the mean and variance for each condition which was adjusted using ANCOVA, t-statistics was performed on every voxel To interpret the results more easily, t-values were transformed to the standard (saussian distri-bution (Z-score). RESULTS: All the subjects carried out the activation and control tests successfully. Average rate of correct answers was 95%. The numbers of activated blobs were 4 for verbal memory I, 9 for verbal memory II, 9 for visual memory, and 6 for canjunctive activation of these three tasks. The verbal working memory activates predominantly left-sided slruetures, and the visual memory activates the right hernisphere. CONCLUSION: We conclude that rCBF PET imaging and statistical parametric mapping method were useful in the localization of the brain regions for verbal and visual working memory.
