Background: The mediastinum is the anatomic space which is restricted and the clinical aspect varies according to location, size and type of neoplasm. Diagnostic and therapeutic approaches to mediastinal neoplasms have changed over and over. We presented our recent therapeutic experiences with these neoplasms. The object and method: The 36 patients were treated in operation from 2000 until 2006. The male patients were 20 and the female patients were 16. Age of the patients ranged from 5 to 70, and the median age was $46.4{\pm}21.9$. The child patients were two. Result: The most prevalent anatomic distribution of the neoplasm was anterosuperior mediastinum. The most common neoplasm was thymoma, followed by thymic cyst, teratoma, ganglioneuroma. The complete excison of neoplasm was accomplished in 96% of patient group except thymoma patient group. One patient underwent total thymectomy, and the other 12 patients underwent extended thymectomy from 13 thymoma patient group. In the malignant neoplasm, 7 patients were received additional treatment after operation. There was short-term death of 1 person and late death of 1 person. Conclusion: Our results except clinical manifestation are compared favorably with other reports. Surgery is the management of choice for patients with mediastinal neoplasm and early curative resection is considered to optimize clinical outcome for patients.

A metastasizing pleomorphic adenoma originating from the parotid gland is a rare form of neoplasm. The neoplasm is a histologically benign, but clinically controversial entity. Herein, a case report of a pleuro-pneumonectomy of a metastasizing pleomorphic adenoma in the right lung is described. A 57-year-old man, who underwent resection of parotid gland due to a pleomorphic adenoma, presented with multiple metastases on the right lung, mediastinum, pericardium and intercostal muscle. The metastatic lesions were composed of a benign pleomorphic structure.

Background: Neuroblastoma is the third most common malignancy of chidhood, and is the most common mediastinal mass in children under the age of 2 years. However, the results of surgical treatment have been seldomly reported in Korea. Therefore, we analyzed the results of surgical treatment in children with neuroblastoma and its influencing factors. Material and Method: We studied the clinical characteristics and prognosis of 12 children, 11 makes and 1 female, whose primary thoracic neurobalstomas or ganglioneuroblastomas were diagnosed and operated between 1977 and 1997. Men age at presentation was 29.9 months. Result: Respiratory symptoms were the modes of performed in 9 patients. Complete excision, partial excision, and biopsy only were performed in 9, 2, and 1 patients respectively. Ten patients of thoractic neuroblastomas survived (83.3%) during follow-up period. Conclusion: The postoperatve 5-year survival of thoracic neuroblastoma was 76.4% and the prognosis was related to the stage of neuroblastoma. We suggest that complete resection should be considered as preferential method in the treatment of thoracic neuroblastoma in children, especially with early stage.

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.

The recommended approach for dumbell trmor is a one-stage removal by a team work of both neurosurgeons & thoracic surgeons. Recently we removed a case of dumbell tumor in a 69 years old woman with standard posterolateral thoracotomy and concomitant laminectomy as single stage operation. Postoperative course was uneventful and there were no postoperative neurologic signs.

Chest wall metastases from malignant tumors are rare and the majority of them are from adjacent structures such as the breast, lung, pleura, and mediastinum. Paticularly, chest wall metastases from distant organs are an even rarer event. There are few reports of chest wall metastasis with obscure or absent primary tumor. A 51-year-old man was diagnosed with metastatic hepatocellular carcinoma after an operation for a palpable mass on his left upper chest wall, At that time, there was no evidence of primary hepatocellular carcinoma in the liver after various examinations. We report a case of chest wall metastasis from unknown primary hepatocellular carcinoma.

We report a 72-year-old male with known myelodysplastic syndrome who presented to the emergency department with a 7-day history of fever and dyspnea. Echocardiography revealed a round echogenic mass $13{\times}16mm$ in size attached to the atrial side of the tricuspid valve. Considering the high risk of infective endocarditis in the patient with a low absolute neutrophil count ($130/mm^3$), emergency surgery was performed. Intraoperatively, a single gelatinous neoplasm was resected, and subsequent reconstruction of the involved leaflet was accomplished using autologous pericardium. The tumor was pathologically confirmed as papillary fibroelastoma with no evidence of infective endocarditis. Papillary fibroelastoma is a rare cardiac neoplasm that occurs in either the mitral or aortic valves. Interestingly, a few cases of tricuspid valve papillary fibroelastoma have been reported so far. Similar echocardiographic findings between vegetation and tricuspid valve neoplasm make it difficult to distinguish these two disease entities.

Solitary fibrous tumor is an uncommon sybnesitgekuak mesenchymal neoplasm that arises primarily from the pleura. Extrapleural solitary fibrous tumors are rare. Solitary Fibrous tumors are often asymptomatic and discovered incidentally but may become symptomatic when vital structures are involved or they grow large. In general, solitary fibrous tumor is diagnosed on the basis of radiologic findings and its histologic features, with immunohistochemistry serving to support the diagnosis. Most solitary fibrous tumors pursue a benign course, and the single most important predictor of clinical outcome is the ability to excise the entire lesion. We experienced a case of intrapulmonary solitary tumor arising from the right lower lobe which was treated with wedge resection. We report this case of the patient.

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.

Calcifying fibrous pseudotumors (CFP) are rare soft tissue tumors that have unique histopathologic features characterized by a dense hyalinized collagenous tissue interspersed with benign spindle cells, lymphoplasmacytic infiltrate, and psammomatous or dystrophic calcifications. We report here on a case of calcifying fibrous pseudotumors in the pleura and provide a literature review.
