Primary tumors of the heart are rare, and one-third of them are malignant. The most common malignant intracardiac tumor is angiosarcoma, which usually involves right atrium. MR features in one patients with right atrial angiosarcoma is presented and the literature briefly reviewed. Angiosarcoma demonstrated slightly heterogeneous intermediate signal intensity on T1-weighted images, high signal intensity on T2-weighted images and higher signal intensity on Gd-DTPA enhanced images. MRI provided more information regarding the extent of the tumor than 2D echocardiography or CT.

Leiomyosarcomas of the stomach are unusual tumors, accounting for 1% to 3% of all malignant tumors and 17% to 20% of all smooth muscle tumors of the stomach. It is difficult to diagnosis these tumors preoperatively because of its vague symptoms and signs or producing symptoms only late. Despite their rarity and difficulty in diagnosis, thier diagnosis is important due to more favorable prognosis aasociated with these tumors than that of gastric carcinoma. Recently, endoscopy is being used with increasing frequency, but because these are submucosal lesions the diagnosis of thease tumors cannot be easily made through the endoscope. We experienced a case of relatively full-brown leiomyosarcoma in gastric fundus. Endoscopy showed 6x6cm sized, definite margined, protruding mass on gastric fundus, with central deep ulceration coated with blood clots. The mucosa overlying the mass was intact, smoothly effaced and the bridging fold was also visible. Postoperative ultrasound showed large protruding mixed echogenic solid mass with contral deep excavation due to ulcer, and intact serosa, so suggestive of endogastric tumor. We believed endoscopy combined with endoscopic ultrasound is probably useful method in early diagnosis of gastric submucosal tumors, especially exogastric type or early small tumors

Superior sulcus or pancoast tumor refers to any primary lung cancer locating in thoracic inlet and causing pain in the periscapular region or arm. These originate in peripheral, and involve the extrapulmonary structures more than arenchyma of the lung. We experienced 1 case of superior sulcus tumor radically resected via anterior transcervical approach, which provided more safe exposure of cervical structures of thoracic inlet than classic posterolateral thoracotomy. Therefore we report this case with review of literature.

Gastational choriocarcinoma is a malignant neoplasm of trophoblast. It may occur after hydatidiform mole, spontaneous abortion, normal pregnancy, and even an ectopic pregnancy. Extragenital choriocarcinoma is a rare tumor which attracts interest because of its controversial pathogenesis. It has been reported to occur within the lung, mediastinum, breast, prostate, thymus, pineal, nose, liver, bladder, and biliary tree, as well as most parts of the gastrointestinal tract. We experienced a case of primary choriocarcinoma of stomach with a metastasis to the liver of a 54-year-old man. So, we present a case with a review of literature.

PURPOSE: An increase of glucose uptake and glycolytic metabolism has been reported in malignant cells as compared with normal cells and tissues. We hypothesized that human erythrocyte glucose transporter-1 (GLUT1) expression is increased in breast carcinoma and may be correlated with long term clinical outcome. METHODS: Two hundred ninety formalin fixed, paraffin embedded sections of infiltrating ductal carcinomas of the breast were immunostained with anti-GLUT1. RESULTS: Among the known clinicopathological prognostic factors, GLUT1 expression was correlated positively with histological grade (p=0.000) and tumor size (p=0.003). In a multivariate analysis, lymph node involvement and GLUT1 expression were statistically significant prognostic factors. The cummulative survival rates of GLUT1 expression and LN involvement were statistically significant (p=0.0061, p=0.0009) respectively. Our results suggest that 1) GLUT1 expression is correlated with histological grade and tumor size, and 2) GLUT1 expression correlates with a poorer prognosis in patients with infiltrating ductal carcinoma of the breast. CONCLUSION: The results of our study suggest that immunohistochemical staining of GLUT1 expression is strongly associated with neoplastic progression in breast carcinoma, and that GLUT1 expression has value in estimating the prognosis of patients with breast carcinoma.

BACKGROUND: Coronary artery bypass graft (CABG) surgery is performed more frequently than before in Korea. Central nervous system (CNS) complications are often the major prognostic determinants following the surgery. We carried out a prospective study to clarify the incidence and risk factors of neurologic complications after CABG surgery. METHODS: A consecutive series of 150 patients undergoing 152 CABG operations from March 1995 to July 1997 by one cardiac surgeon was evaluated by a team of neurologists before and after the surgery. The patients received extensive preoperative examinations including the evaluation of intracranial & extracranial cerebral artery disease. RESULTS: In 44 operations (28.9%), we detected various neurologic complications, including encephalopathy (36 operations, 23.7%), cerebral infarction (5 operations, 3.3%), and seizure (7 operations, 4.6%). Eight patients died postoperatively including one due to neurologic complication. On univariate analysis, age, degree of intracranial artery disease (ICAD), duration of bypass time, hypotension index, duration of ventricular assistant device (VAD), intraoperative event, intra- or postoperative arrhythmia, reoperation, and postoperative bleeding were statistically significant risk factors of CNS complications (p< 0.05). After multivariate analysis, however, age alone remained significant (p=0.02). The degree of ICAD showed marginal significance (p=0.06). CONCLUSIONS: The incidence of CNS complication in the patients undergoing CABG surgery was 28.9%. Our results showed that age was an independent risk factor of CNS complications. And the possibility of ICAD as a risk factor was suggested. Further study with a large number of patients would be necessary to prove the above suggestion.

PURPOSE: To compare 3D ultrasound (3D-US) with 2D ultrasound (2D-US) in terms of their usefulness and limitations in the diagnosis of breast masses. MATERIALS AND METHODS: We obtained 2D and 3D US images of 37 breast lesions present in 20 cases of fibroadenoma, nine of cancer, and eight of fibrocystic disease proven in a total of 26 cases [fibroadenoma (n=13), breast cancer (n=9), fibrocystic disease (n=4)] by histologic examination, and by clinical evaluation and clinical evaluation with sonographic imaging in eleven. When comparing 3D and 2D-US images we had no prior information regarding detection rate according to the size of lesions, whether or not internal and boundary echo patterns could be interpreted, accurate differentiation between tumorous and non-tumorous lesions, or the accuracy with which benign and malignant tumors could be differentiated. RESULTS: For lesions of 1 cm or less in diameter the detection rate of 3D-US was lower than that of 2D-US, but for lesions over 1 cm there was no difference between the two modalities. In fibroadenoma and breast cancer, 3D-US was more useful than 2D-US for the evaluation of both internal and boundary echo, but with fibrocystic disease and in the diagnosis of tumor/non-tumor, there was no significant difference. In breast cancer, however, 3D-US more accurately determined malignancy, and in fibroadenoma, because of the pseudospicule revealed by 3D-US, this modality was less exact in determining benignancy. CONCLUSION: In the evaluation of internal and boundary echo in breast mass diagnosis, 3D-US was more useful than its 2D counterpart. For lesions of 1 cm or less in diameter, however, the detection rate of 3D-US was low, and since in some benign cases a pseudospicule was apparent, the possibiliy of confusion with malignancy arose. For these reasons, the usefulness of 3D-US was limited.

Trichuriasis is an intestinal infection of human beings caused by Trichuris trichiura, more commonly known as whipworm because of its whip-like appearance. It is characterized by the invasion of the colonic mucosa by the adult trichuris. It is prevalent throughout the world, especially in tropical areas. Diagnosis is made typically by the identification of characteristic barrel-shaped eggs in the feces, although adult worms may be seen rarely at sigmoidoscopy or colonoscopy. We report five cases of whipworm infection that was diagnosed on colonoscopic examination.
