The thoracic duct cyst is an extremely rare cystic lesion in the mediastinum. Surgical treatment of the cyst is necessary to confirm histologic diagnosis and prevent potential complications such as spontaneous or traumatic rupture of the cyst and chylothorax.

Tumors of the mediastinum are usually classified according to their location in the anterior, middle, or posterior mediastinum. Mediastinal teratomas are characteristically located at anterior mediastinum with only rare incidence in the posterior mediastinum. Two cases of posterior mediastinal teratoma were experienced recently, in the department of thoracic surgery, Seoul National University Hospital. The incidence of posterior mediastinal teratoma was 4.2% among 48 mediastinal teratomas in our experience. Two cases are all benign teratoma located at right posterior costophrenic angle, and histologically showed tissues from three germ layers including bone and fat.

Synovial sarcoma is a malignant soft tissue tumor that primarily occurs in the praarticular regions, especially in the knee. They are composed of keratin-positive epithelial cells and vimentin-positive spindle cells. We report a 76 year old woman with a primary synovial sarcoma in the mediastinum that had severe adhesion to the right side of pericardium. Primary synovial in the midiastinum is extremely rare and this is the first case reported in the Korean literature. The mass including the pericardium was resected and the defect was closed with Gore-Tex patch. The patient is well and free of disease 6 months after the operation.

The cavernous hemangioma often occur on the skin and mucosal surfaces of the body, but are also found in many viscera, particularly the liver, spleen, pancreas and occasionally in the brain. But it is rarely encountered in the mediastinum, but when found occur predominantly in the anterior mediastinum. It can occur in any age and have no characteristic symptoms or roentgenographic findings including angiocardiography. Inspite of its histologic benignancy, it may be locally invasive and can result in rib erosion or adjacent structural compression. Usually, surgical exploration is not only the sole means of assuring a diagnosis and the only treatment. Recently, we experienced one case of cavernous hemangioma in the anterior mediastinum, which was removed surgically, being proved to be cavernous hemangioma on histologic examination. Related literatures were reviewed.

Endodermal sinus tumor[EST] of the mediastinum is a rare germ cell neoplasm. It usually arises from the ovaries and testes but also arises from multiple extragonadal site including the mediastinum. Characteristically, alpha feto protein level is high and used for monitoring the clinical course. EST of the mediastinum is poor prognosis because of its direct invasion. The patient was 18 month old female with chief complaints of cough and fever. In the chest X-ray and CT, large encapsulated, 7x6cm sized, mass of anterior med-iastinum was found, and we could excise it completely because it was well encapsulated and not invaded but only adhered to aortic arch, pericardium and left upper lung. And confirmed it as EST by histopathology. Pre-operative alpha feto protein[AFP] level as 41,748ng/ml and decreased to 2, 663ng /ml at 14th postoperative day, 644ng /ml at 31th postoperative day. From 17th post-operative day, chemotherapy was started and keep going now.

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis. Due to its low incidence, there is no standard treatment for mediastinal EHE, but curative resection is the preferred treatment option where possible, with chemotherapy used as an adjuvant treatment or in cases of widespread inoperable disease. The present case study describes an aggressive EHE occurring in an 18-year-old woman in the anterior mediastinum.

A case of bronchogenic cyst of the posterior mediastinum in a boy of 5 years of age was encountered at Seoul University Hospital. Scarcity of case reports in Korea and Japan suggests that bronchogenic cyst is a relatively rare entity in the Far East.

In mediastinum, teratoma frequently occur in anterior mediastinal compartment. Rarely discovered in pericardium, posterior mediastinum and lung parenchyme. The incidence of posterior mediastinal teratoma was 3%~8%. A young male patient was treated with posterior mediastinal teratoma. So we describe the rare disease.
