Pleomorphic adenoma is also called a mixed tumor and it most commonly occurs in the salivary gland. This neoplasm has a low grade malignant potential, but it may also show aggressive clinical behavior like recurrence or metastasis. We report here on a case of a tumor that was confirmed to be primary pulmonary carcinoma ex-pleomorphic adenoma by the pathologic examination after complete resection, and it had the characteristics of malignant neoplasms, such as multiple metastases.

Primary cardiac lipoma is an extremely rare condition. We reports a case of primary lipoma located mainly in the right atrium of the heart in a 58-year-old male patient. The initial presenting symptoms were dyspnea followed by rapidly progress!ve congestive heart failure. Echocardiogram revealed huge mass on right atrium with stalk arising from septum. Under cardiopulmonary bypass the mass was removed and revealed characteristic findings of lipoma on microscope. The patient was recovered without any problem. We would like to describe this case of rare tumor with the review of literatures.

We report a case of a resection of very large intracavitary metastatic malanoma causing obstruction of the right ventricular inflow and outflow tract of the heart. A 49-year-old woman with dyspnea and generalized edema was seen. Echocardiography reveal an intra cavitary mass occupying the entire right ventricle and pericardial effusion. The lesion was palliatively resected using a cardiopulmonary bypass and was confirmed as a malignant melanoma. The patient is alive and improved symptomatically 30days after the operation.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.

An occurrence of hemangioma in the mediastinum is a very rare, accounting for less than 0.5% of mediastinal tumors. Capillary hemangiomas and cavernous hemangiomas consists of over 90% of mediastinal hemangiomas. However, venous hemangioma has never been reported in South Korea and has also very rarely been reported worldwide. We found mediastinal solid mass, as an incidental finding during a follow-up chest CT scan of a 44-year-old female patient who had undergone colon cancer surgery. We performed a mediastinoscopic biopsy. We did a thoracotomy to remove this mass because hemorrhage and found a totally resected venous hemangioma.

Background: Tumors of the heart are uncommon. The aim of this study is to review our clinical experience and outcome of surgical treatment of cardiac neoplasm. Material and Method: From March 1990 to December 2005, 35 patients(14 males and 21 females) with mean age of 52.4 years underwent surgical treatment of cardiac neoplasm. The clinical and pathologic data were analyzed retrospectively. Surgical treatment consisted in complete resection of the tumor in all cases but 1 patient who was left ventricular fibroma received biopsy only. Result: Thirty cases were benign and five cases were malignant tumor. Benign tumors were myxoma(29 cases) and fibroma(1 case). Five malignant tumors were osteosarcoma, hepatocellular carcinoma, renal cell cancer, yolk sac tumor, and unclassified myxoid spindle cell type sarcoma. There were no operative mortality in benign cases and twenty seven cases of myxoma were followed up for 8 months to 15 years without recurrence. But four patients of malignant tumor were expired within six months after operation. Conclusion: Left atrial myxomas are most common benign neoplasm. Surgical treatment is effective for the benign cardiac tumors but prognosis is poor in patients with malignant cardiac tumors.

Primary cardiac tumors are known to be rare. Of the benign primary tumors, rhabdomyoma predominates in neonates and infants. Tuberous sclerosis is found in hall of the patients with rhabdomyomas. Rhabdomyomas demonstrate benign pathological characteristics and may regress spontaneously that resection of the intracavitary obstructing portion of these tumors are recommended. We performed resection of intraatrial rhabdomyoma which had been obstructing mitral valve orifice and caused heart failure in a neonate. Postoperatively, fungal endocarditis developed and after 3 days, rapid growth and extension of the vegetation in the aorta obstructed the flow through the ascending aorta and resulted in hemodynamic deterioration.

Solitary fibrous tumor is a spindle cell neoplasm that can arise in any place of the body. Intracranial solitary fibrous tumors are rare. To our knowledge, only 57 cases with intracranial lesion have been reported. In Korea three cases have been reported. Our case was a 23-year-old woman who presented with morning headache. MRI showed a large intra-axial mass involving falx with typically isointense and heterogeneous strong enhancement on T1 weighted image in the right parieto-occipital region. Histologically the tumor showed spindle shaped cells within matrix with thick collagen deposition, hypercellularity, focal necrosis, and pleomorphism. Immunohistochemical study demonstrated diffuse positivity for CD34, Vimentin, Reticulin. In case of the intracranial tumors involving the meninges, we also should consider the solitary fibrous tumor with immunohistochemical staining for accurate diagnosis.

Paraganglioma is a rare tumor of paraganglia, derived from neural crest cells in sympathetic or parasympathetic ganglions. It can be widely distributed from the skull base to the bottom of the pelvis. The pancreas, however, is a rare location of this neoplasm, and only a limited number of cases have been reported in the English literature, especially with gadoxetic-acid-enhanced magnetic resonance imaging (MRI) and diffusion-weighted images (DWI). We herein report a case of pathologically proven paraganglioma in the pancreas head with a literature review on endoscopic ultrasonography (EUS), computed tomography (CT), gadoxetic-acid-enhanced MRI, and DWI sequence.
