Hemangiomas of mediastinum are rare lesions comprising less than 0.5% of all mediastinal masses. Posterior mediastinal hemangiomas are less common than anterior mediastinal. A 21 year old female was refered to our hospital because of abnormal mediastinal shadow in simple chest X-ray. Chest CT scan and T-spine MRI revealed a posterior mediastinal dumbbell-shaped mass with extradural extension. Surgical excision was performed and pathologic diagnosis was confirmed as 3${\times}$4${\times}$2 cm sized capillary hemangioma.

Pheochromocytomas are neuroendocrine tumors of chromaffin cell that originate in the paraganglia of the adrenal medulla. Approximately 10% of pheochromocytomas are found in the extra-adrenal paraganglia and are called paragangliomas. However, cases of middle mediastinal paragangliomas are very rare. In this case, the patient presented with a voice change and a headache. A middle mediastinal soft tissue mass with marked enhancement was detected on computed tomography of the chest. The 24-hour urine catecholamine level was markedly elevated. The middle mediastinal mass was biopsied via mediastinoscopy and the resulting immunohistochemical staining was compatible with a diagnosis of middle mediastinal paraganglioma. The mass was resected surgically and the symptoms were relieved.

Thoracic extramedullary hematopoiesis (EMH) is a rare disease entity that is usually associated with hematologic disorders, such as myelodysplastic or hemolytic disease. Because thoracic EMH is usually encountered as a mass during radiologic examinations, it should be differentiated from posterior mediastinal neurogenic tumors. Here, the authors report a case of EMH associated with hereditary spherocytosis. The patient underwent a complete excision by thoracoscopic surgery to differentiate it from other mediastinal tumors.

A 59-year old woman visited us for incidentally detected posterior mediastinal mass. Preoperative esophagography, esophagoscopy, esophageal ultrasound and computed tomography showed a esophageal submucosal tumor. With the diagonsis of esophageal leiomyoma, the patient underwent right side video-assisted thoracoscopic surgery (VATS): The mediastinal pleura and the esophageal muscle layers were longitudinally opened and the tumor was enucleated. Esophagography performed at 6th postoperative day revealed no esophageal mucosal bulging or leakage. The patient was discharged reveiving a soft diet on the 7th postoperative day.

Thoracic duct cysts in the upper portion of the diaphragm are mostly found in the neck and are rarely found in the mediastinum. Thoracic duct cysts should be differentiated from other mediastinal tumors or cysts, and surgical treatment is required to avoid the development of chylothorax if the cyst ruptures. Herein, we report the case of a patient with a thoracic cyst located just above the diaphragm that was treated with surgical resection.

A retrospective analysis was performed on 36 patients with primary cysts and tumors of the mediastinum seen at the Department of Thoracic and Cardiovascular Surgery of Maryknoll Hospital from January 1983 to December 1993. There were 21 female and 15 male patients in the study. Ages ranges from 2 years to 72 years, with a mean of 34.7. There were 9 malignant tumors and 27 benign tumors.Thymic neoplasms were the most common. For the whole series, 29 of the patients had tumors in the anterior mediastinum. There appears to be an in6rease in tumors in the anterior compartment. There were 30 symptomatic patients in our series. Of the patients with malignant disease, 89 % were symptomatic. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation. There were 9[27.3 %] postoperative complications. There was no postoperative mortality. Follow-up was available on 27 patients. There was no recurrence, malignant degeneration, or growth of any tumor. It is hoped that careful evaluation and aggressive treatment of mediastinal tumors will continue to provide improvement in the prognosis for these patients.

Lymphangiohemangiomas of the mediastinum are exceedingly rare and few cases have been published in the English literature. This report may be the only reported case in which lymphangiohemangiomas were found bilaterally. We report a case of a 7-year-old boy with an incidental finding of an abnormal mediastinal shadow on a chest X-ray. The chest CT showed a large mass in the left superior mediastinum and another in the right posterior mediastinum. The left mass had anomalous venous channels connected to the left innominate vein, and the right mass to the left atrium. We performed an excision of the mass in the left side first and then the right side one month later. Anomalous venous channels were dissected carefully and ligated. There were no complications and no signs of recurrence 30 months after the operation.

Chordoma is a rare malignant bone tumor originating from the embryonic notochord. Herein, we present a case of thoracic chordoma located at T3-T5 that was misdiagnosed as primary mediastinal adenocarcinoma. The patient underwent neoadjuvant chemoradiation and the disease showed little response. Due to vertebral body invasion, we performed en bloc mass removal and partial corpectomy (T4-5) in collaboration with orthopedic surgeons.

A 15-year-old male was admitted with right-sided chest pain and cough for one month. On chest computed tomographic scan, a $10\times15\times16$ em-sized huge mediastinal mass was occupied in the right hemithorax. Radiologically, it seemed that the tumor was severely adhesive on the heart and the superior vena cava. Therefore we decided on chemotherapy and radiotherapy first instead of surgery. The tumor marker was nearly normalized afterwards, but the tumor size was seemed to be bigger on chest tomographic scan. This suggests the growing teratoma syndrome. After the successful resection, he showed symptomatic improvement and is being followed up without any symptoms in an out patient department up to now.

DiGeorge syndrome is an immunodeficient disease associated with abnormal development of 3rd and 4th pharyngeal pouches. As a hemizygous deletion of chromosome 22q11.2 occurs, various clinical phenotypes are shown with a broad spectrum. Conotruncal cardiac anomalies, hypoplastic thymus, and hypocalcemia are the classic triad of DiGeorge syndrome. As this syndrome is characterized by hypoplastic or aplastic thymus, there are missing thymic shadow on their plain chest x-ray. Immunodeficient patients are traditionally known to be at an increased risk for malignancy, especially lymphoma. We experienced a 7-year-old DiGeorge syndrome patient with mediastinal mass shadow on her plain chest x-ray. She visited Severance Children's Hospital hospital with recurrent pneumonia, and throughout her repeated chest x-ray, there was a mass like shadow on anterior mediastinal area. We did full evaluation including chest computed tomography, chest ultrasonography, and chest magnetic resonance imaging. To rule out malignancy, video assisted thoracoscopic surgery was done. Final diagnosis of the mass which was thought to be malignancy, was lymphoproliferative lesion.
