A 52-year-old man was taken to the emergency room following a motor vehicle accident. An echocardiogram showed moderate to severe tricuspid regurgitation due to rupture of the anterior chordae. An operation to repair the traumatic tricuspid regurgitation was recommended; however, the patient refused because he was asymptomatic. Two years later, he developed mild generalized edema and dyspnea. The echocardiogram revealed progressive severe tricuspid regurgitation and annular dilatation. We treated the posttraumatic tricuspid regurgitation successfully using artificial chordae and ring annuloplasty.

Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors analyzed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent 6 years. The most common tumor was thymoma (9 cases), and teratoma (6 cases), lymphoma (6 cases), bronchogenic cyst (4 cases), neurogenic tumor (4 cases), pericardial cyst (1 case) were next in order of frequency. There were 5 cases of thymoma showing homogenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases. A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomonic fat, and calcified density were seen only in 4 cases. 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma (3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor (2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, 1 was located in subcarinal and 1 was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.

Inflammatory myofibroblastic tumor (IMT) is a space occupying lesion which is composed of myofibroblasts, plasma cells, and lymphocytes. IMT of the maxillary sinus is rare and its etiology is unknown. We present a case of inflammatory myofibroblastic tumor occurring in the right maxillary sinus of a 57-year-old woman. Radiologically, this tumor was interpreted as malignant neoplasm. On histologic examination, bundles of spindle cells were admixed with inflammatory cells including mature plasma cells and lymphocytes. On the basis of the immunohistochemical findings and ultrastructural features, we recognized that the intervening spindle cells were myofibroblasts. We discussed etiology and prognostic factors of this tumor.

Background : It has been suggested that thrombospondin (TSP) is a p53-dependent negative regulator of tumor angiogenesis. TSP expression and localization in hepatocellular carcinomas (HCCs) and its association with overexpression of p53 protein were investigated. Methods : TSP-1 and -2 expressions were examined in 40 HCC specimens by immunohistochemical staining and in 4 HCC cell lines by Western blotting. In addition, p53 protein expression and microvessel density (MVD) were correlated with the TSP expression. Results : Strong immu- nopositivity for TSP-1 was observed in fibroblasts, vascular endothelial cells, and some vas- cular smooth muscle cells of the stroma in 18 cases (45%), and in tumor cells in 3 cases (7.5%) of 40 cases of HCC. Immunoreactivity for TSP-2 was observed in only the sinusoidal lining cells of the tumor in 15 cases (46%), and in tumor cells in 2 cases (6%) of 32 cases of HCC. TSP-1 expression was inversely correlated with MVD (p=0.028), but TSP-2 expression did not show any correlation with MVD. Although p53 was overexpressed in 17 cases, there was no significant correlation between TSP and p53 expressions. None of the HCC cell lines expressed TSP-1 or -2. Conclusions : These findings indicate that TSP-1 is mainly derived from nonparenchymal cells, and may decrease tumor angiogenesis in HCC.

A case of Wegener's Granulomatosis of 35 year old Korean male having 38 months duration with typical clinical symptoms and coular manifestations had been treated and observed in our clinic form April to November 21, 1958. The diagnosis was confirmed by the histopathological studies on biopsy specimen and by postmortem examination. The ultimate cause of the death in this case was thought to be massive cerebral hemorrhages as a result of systemic involvement of necrotizing angitis which is one of the characteristic features of this disease. Uremia and hypertension were not observed in this case to the end of the course. There is no report dealing with Wegener's Granulomatosis in Korean literatures to the best of our knowledge at this moment.

A 50 year old male patient was admitted due to fever and left upper-quadrant abdominal pain. He had a history of previous treatment for pulmonary TB and splenectomy due to aplastic anemia. A large peritoneal abscess with connection to a chronic left side tuberculous empyema thoracis was diagnosed on admission. Chest CT also revealed a soft tissue lesion on the left anterior chest wall. Staged drainage of the peritoneal lesion followed by left side pleuropneumonectomy with chest wall resection was performed. The pathologic studies showed a high grade sarcoma of the chest wall.

Histiocytomas have rarely been reported in the lungs. We report an unusual benign pulmonary histiocytoma in a 45-year-old man and discuss the differential diagnosis. Chest CT showed a well-defined solitary pulmonary nodule of approximately 3 cm in size in the posterobasal segment of the right lower lobe. Posterolateral thoracotomy and wedge resection was performed. Gross examination revealed a mass, measuring 2.2 x 2.1 cm that had a circumscribed margin within the lung parenchyma. Microscopically, the tumor was entirely composed of large polygonal to round cells with a few chronic inflammatory cells. These tumor cells contained abundant cytoplasm which was either granular, eosinophilic or foamy. Immunohistochemically, these cells were diffusely positive for CD68 and focally positive for 1-antitrypsin, but negative for cytokeratin, vimentin, and smooth muscle actin.
