We report a rare case of rhabdomyosarcoma spontaneously arising in an anterior mediastinal teratoma in a 47-year-old male. The patient was found to have an anterior mediastinal mass on a chest X-ray, which was taken two months before his presentation to Asan Medical Center. A subsequent computed tomography scan revealed an $8.9{\times}7.1{\times}8.0$ cm heterogeneous mass in the anterior mediastinum. He underwent an excision via median sternotomy. The histopathologic study identified a mature teratoma with embryonal rhabdomyosarcoma.

Cavernous hemangiomas of the mediastinum are rare tumors. A 3 year and 8 month-old female patient was referred because of an abnormal chest radiograph. Chest X-ray revealed abnormal shadow occupying nearly the entire left thoracic cavity Surgical excision was performed and pathologic diagnosis was confirmed as 15 $\times$ 10 cm sized cavernous hemangioma. On the eighth postoperative day, the patient was discharged without any complications and has been followed up without any problems.

Castleman's disease is a relatively rate disorder of lymphoid tissue and poorly understood etiology. The disease may occur anywhere along the lymphatic chain, but is most commonly found as a solitary mass in the mediastinum. The hyaline vascular type represents 91% of Castlemen's disease, and these are most often discovered in the asymptomatic patient on routine chest film. Patients with the plasma cell type often exhibit systemic symptoms, including fever, night sweats, anemia, and hypergammaglobulinemia. Surgical excision effects cure, although resection of the hyaline vascular type may be associated with significant hemprrage owing to extreme vascularity. We recently experienced a case of hyaline vascular type Castleman's disease which was treated by surgical resection through the anterior mini-thoracotomy, and report with its review.

A case of liposarcoma was reported in 52 year-old female. She had the operation history due to mediastinal lipoma at other Hospital before 26 months ago. Chest X-ray revealed a huge soft tissue mass- density at the entire right lung field, and left middle and lower lung field at admission. At the lateral film, the mass was located in the anterior and middle mediastinum. Transsternal bilateral thoracotomy was performed, followed by extirpation of liposarcoma, wedge resection of superior vena cava, angioplasty of superior vena cava, and then partial pericardiectomy. The post-operative treatment was 5500 rad irradiation. Post-operative course was uneventful, that was noticed by OPD follow-up for 10 months. Primary liposarcoma of the mediastinum is very rare tumor. This tumor grows to an enormous size, and symptoms are referable to compression of the contiguous intrathoracic structures. The treatment of choice is surgery in all cases. Such an approach serves to establish a tissue diagnosis, to relieve the patients* symptoms, and may results in a cure sometimes. Radiotherapy or/and chemotherapy seems to be ineffective, but should be further studied.

A solitary fibrous tumor in the pleura has been reported occasionally, but extremely rare in themediastinum. The histogenesis of this tumor has been still in controverse, but recent studies paid attention to it a mesenchymal origin by the immunohistochemical and ultrastructural bases. A few cases, reported in the literature, suggest that the mediastinal solitary fibrous tumor occurs more commonly in adult and shows slightly higher incidence in women. Its aggressive behavior such as recurrence rate and distant metastasis, is more prominant than reported in solitary fibrous tumor of the pleura. No single histologic feature allows an assumption definite prognosis. Surgical resection of this tumor is usually curative although the recurrence or distant metastasis are reported in about half of the patients. This report is a case of solitary fibrous tumor in the mediastinum in a 16-year-old female patient.She underwent surgical resection and her postoperative result was satisfactory.

The Nuss procedure has good cosmetic effects, but it could be cause of bleeding and organ injury during dissection of the anterior mediastinum. We have made an effort to overcome the defects of the traditional method through the anterior mediastinum, thus we developed a transilluminated introducer that made it safer and simpler to operate within a 1cm incision only. A total of 67 patients underwent the Nuss procedure using the transilluminated introducer. Thirty-six patients underwent the procedure with the transilluminated introducer only (age<4 years). Thirty-one patients had an additional thoracoscopy ($age{\geq}14\;years$). There were no major complications, such as massive bleeding or organ injury in the thoracic cavity during or after the Nuss procedure. Our findings demonstrated that the anterior mediastium could be dissected simply and safely by the use of a transilluminated introducer during the Nuss procedure without fatal major complications, such as bleeding and organ injury.

The Mixed germ cell tumors of the mediastinum are very quite rare. The Prognosis is generally dominated by the most aggressive component, which is represented by a choriocarcinoma, an endodermal sinus tumor, an embryonal carcinoma, and a seminoma, in descending order of in the degree of malignancy. We experienced one a case of a mixed germ cell tumor at the anterior mediastinum. The patient was 27-year-old male, who complained of hemoptysis and cough. The Chest X-ray showed a well-defined lobulated mediastinal mass in the left upper lung field. The operation was done and The mass was excised surgically. A Biopsy showed elements of mature tissues, immature neuronal components, and seminoma components.

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 ana lysed 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 thymona(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 pathognomic 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.

This report describes the case of a 57-year-old man with an anterior mediastinal tumor. Four years previously, he underwent laparoscopic anterior resection for sigmoid colon cancer. Thirty months after that procedure, bilateral pulmonary metastasectomy was performed. Twelve months later, follow-up computed tomography revealed a 1-cm pulmonary nodule on the upper lobe of the right lung and a solid mass on the anterior mediastinum, and the patient was also observed to have an elevated serum carcinoembryonic antigen (CEA) level. Repeated pulmonary nodule resection and total thymectomy were performed. Immunohistochemical staining of the anterior mediastinal tumor revealed adenocarcinoma, and his serum CEA level returned to normal after the operation. These findings strongly suggested metastatic thymic adenocarcinoma from a colorectal cancer.

All most of all seminoma occurred in anterior mediastinum, and generally appeared as large masses on routine chest film. The tumors are radiosensitive and the prognosis is relatively good. Recently we experienced one case Of seminoma, who is 28-year old male and asymptomatic at seminoma. In our case, the size of the tumor is strikingly reduced after radiation therapy.
