Endoscopic removal is acceptable for the treatment of endotracheal/endobronchial mass, because it is less invasive in high-risk patients and a conservative procedure for benign tumors. Two benign tumors in the lumen of the trachea (pure lipoma) and in the intermediate bronchus (hamartoma) were completely eradicated by our procedures, which involved diathermic snaring and residual mass removal with biopsy forceps under the guidance of fiberoptic bronchoscopy. No tumor recurrence was evident after extended follow-up (6 years for endotracheal lipoma and 2.5 years for endobroncheal hamartoma). Our method is safe and less invasive for the patient and provides the surgeon with better view during procedure.

Pneumocephalus after thoracoscopic excision of a mediastinal mass is a very rare complication. It presumably occurs due to dural injury near the spinal root and development of a subsequent subarachnoid-pleural fistula. A 60-year-old woman complained of nausea and headache after thoracoscopic excision of a posterior mediastinal mass. She was diagnosed with pneumocephalus by brain CT and recovered with supportive management.

The primary mediastinal liposarcoma is a very rare tumor. It mainly causes respiratory symptoms, but can be asymptomatic. The most favorable treatment of primary mediastinal liposarcoma is a surgical removal, whether it is complete or not, regardless of the size or histologic type of the tumor. The survival is determined by the histologic type of tumor. A 34-year- ld man was admitted because of asymptomatic mediastinal tumor which was progressively growing over 6 years. The tumor was completely resected and the microscopic findings of the tumor were compatible with well-differentiated liposarcoma. The patient recovered and discharged without complication on the 7th postoperative day.

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.

Malignant fibrous histiocytoma (MFH) is a tumor which most often develops in the soft tissues of the extremities and retroperitoneum, but very rarely originates in the mediastinum. We report a 71-year-old man who admitted with anterior mediastinal tumor and underwent surgical resection of tumor in our hospital. The mass was histologically confirmed as MFH.

혈관에서 기원되는 종양은 혈관외피 세포로부터 발생되는 종양 혈관외피종과 glomus tumor)관 혈관내피 세포로부터 발생되는 종양(를상피 혈관내피종)의 두가지로 구분된다. 이들은 매우 드물게 발생되며 악성종양의 특성을 가지고 있는데, 폐에서 발생된 경우에는 무증상의 작은 종괴로부터 증상이 있는 커다란 종양 의 형태로 나타난다. 최근 저자들은 단일성의 유상피 혈관내피종과 혈관외피종 각각 1례를 치험하였기에 문헌고찰과 함께 보 고하는 바이다. a Tumors of vascular origin are subdivided into two groups: those composed of pericytes (hemangiopericytoma and glomus tumor), and those composed of endothelial cells(hemangioendothelioma). They are uncommon, potentially malignant tumors, and in the lung, the tumors may present as a small asymptomatic nodule or a large symptomatic lesion. Recently we experienced two cases of solitary pulmonary vascular tumors(epithelioid hemangioendothelioma and hemangiopericytoma), and reviewed them with references.

Primary cardiac tumors are rare disease and they present nonspecific symptom. They are divided in benign and malignant tumors and require surgical therapy and/or additional therapy. From March 1995 to March 2003, twenty one patients were diagnosed as having primary cardiac tumors. We analysed them retrospectively in terms of various perioperative factors and early and late results. 6 men and 15 women and their average age was 45.44$\pm$18.76. Pathology revealed eighteen benign (fourteen myxoma, two fibroelastoma, one hemangioma and one paraganglioma) disease and three malignant (one angiosarcoma, one mesothelioma and one myxofibrosarcoma) disease. There was one (myxoma) operative mortality and three late death (hemangioma, angiosarcoma and mesothelioma) during additional therapy and follow up. Surgical treatment of primary cardiac tumor is important and sometimes additional therapy is required but the prognosis of malignant cardiac tumor is still very poor.

A recurrent myoepithelioma of the lung in a 36-year-old man is reported. The neoplasm showed histologic features identical to those described in myoepitheliomas of major and minor salivary glands on the basis of Dardick's morphological classification of Myoepitheliomas. He was treated totally with surgical en-bloc resection including the chest wall. The tumor was found to be well encapsulated, and it appeared to be mainly composed of plasmacytoid cells and clear cells with occasional microcystic spaces in a solid growth form by light microscopy. Immunocytochemical, ultrastructural and flow-cytometrical studies supported myoepithelioma differentiation.

Herein we report a rare case of primary esophageal malignant melanoma in a 56-year-old gentleman who presented with a 2-month dysphagea. Esophagoscopy reveals a polypoid tumor and a total thoracic esophagectomy was performed through a right thoracotomy and esophageal replacement with stomach. The tumor was proven to be a primary esophageal malignant melanoma by histological and immunohistochemical studies. The pathologic stage was IIa. He received no postoperative adjuvant therapy. He died of liver metastasis at 8 months postoperatively.

Intrathoracic goiters consist of two types: the primary and secondary type. Primary intrathoracic goiters are very rare. We report here on a case that was resected with using the thoracoscopic assist technique. The transthoracic or transsternal approach is necessary for primary goiters to remove them completely without complications.
