The mucoepidermoid cancer is a tumor arising in the bronchial submucosal glands that shows an intimate admixture of glandular element and sheets of cell with or no definite squamous differentiation. This rare tumor is usually located in lobe and bronchi and occasionally in the trachea. This tumor presents with symptoms of bronchial irritation or obstruction, often of several years duration. The treatment is complete resection with use of bronchoplastic techniques.Low grade tumor have a good prognosis with adequate resection. We experienced a case of mucoepidermoid cancer arising from superior segment of left lower lobe, which was treated with Lt.lower lobectomy.

A 64-year-old man was admitted for gross hematuria. Preoperative study revealed right renal cell carcinoma with inferior vena cava(IVC) tumor thrombus. Right radical nephrectomy was performed, and deep hypothermic circulatory arrest(DHCA) with retrograde cerebral perfusion(RCP) was used for extraction of tumor thrombus in the IVC. The thrombus originated from the right kidney, which extended the orifice of the gonadal vein in the left renal vein laterally, the hepatic vein superiorly, and 3cm below the right renal vein inferiorly. The thrombus was removed completely without caval wall injury under DHCA with RCP, and the postoperative course was uneventful. He received immunotherapy with interferon, and followed up without any surgical problem.

Thymolipoma is a rare benign tumor consisting of fat and thymic tissue. Approximately 60 case reports have been published. On 1984, one patient with proven mediastinal thymolipoma was treated surgically at the Department of Thoracic & Cardiovascular surgery, Seoul National University Hospital. The following case is the first reported example of thymolipoma occurring in Korea.

This is the result of the annual statistic analysis of thoracic and cardiovascular surgical cases in 1992 Korea. Overall 17, 520 cases of surgery [11, 732 cases of thoracic surgery by 54 institutes / 5, 788 cases of cardiovascular surgery by 48 institutes] were done. 1. Tumor [N=2, 532] : Lung was the most frequently involved organ by tumor [54.9%],and the remainders were mediastinum [16.2%] / esophagus [14.8%] / chest wall [11.7%] / tracheobronchus [1.3%] / pleura [1.1%] in order. Of 1, 082 cases of primary lung cancer surgery,the frequency of cell type was squamous [62.6%] / adeno [21.6%] / small cell [7.1%] / large cell [2.7%]. Of 411 cases of mediastinal tumor surgery,the frequency of cell type was neurogenic [28.8%] / thymoma [27.6%] / teratoma [17.7%] / congenital cystic [17.2%]. Of 376 cases of esophageal tumor surgery,primary cancer were the most [85.4%]. 2. Infection [N=3, 157] : Pleura was the most frequently involved organ [59.0%],and the remainders were lung [31.3%] / chest wall [8.6%] / mediastinum [1.1%] in order. 3. Miscellaneous [N=6, 043] : Lung and pleural disease esp. pneumothorax [85.1%] was the most frequent surgical indication. The remainders were chest wall anomaly [3.4%] / benign esophageal disease [3.4%] / diaphragmatic pathology [2.4%] / myasthenia [1.4%] in order. Of 85 cases of thymectomy for myasthenia gravis,thymoma was noted in 58.8%. 1. Congenital heart disease [N=3, 363] : The ratio of noncyanotic to cyanotic heart disease was 3:1. Of 2, 516 cases of noncyanotic heart disease,the frequency of disease entity was VSD [44.1%] / ASD [26.0%] / PDA [19.4%] / PS [3.3%],and that of 847 cases of cyanotic heart disease was TOF [29.4%] / ECD [15.6%] / TGA [9.7%] / DORV [7.6%]. Overall mortalities were 2.1% in noncyanotic and 12.2% in cyanotic heart surgery. 2. Acquired heart disease [N=1, 929] : Of 1, 422 cases of valvular surgery,single mitral pathology was the most frequent candidate [48.0%],and total 1, 574 prosthetic valves which were mainly mechanical [95.6%] were used. Of 376 cases of coronary surgery,triple vessel was the most [35.9%],and the frequency of bypassing grafts was great saphenous vein [52.9%] / internal mammary artery [44.7%] / artificial vessel [2.4%]. Overall mortalities were 3.4% in valvular and 4.5% in coronary surgery. 3. Pericardium,Cardiac tumor,Arrhythmia,Aortic aneurysm,Assist device,and Pacemaker : There were no specific changes compared to previous survey1]. This nation-wide inquiry will be continued and reported annually by KTCS Society.

Synovial sarcoma is a malignant soft-tissue tumor that most commonly occurs in the extremities of young adults. There have been several cases of synovial sarcomas of the pleural and lung reported, but synovial sarcoma arising from the chest wall in childhood is very rare. Here we report a case of synovial sarcoma arising from the chest wall in a 3 year-old female patient. The tumor was completely resected. No adjuvant therapy was given. The patient is well 3 years after the operation.

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.

Cardiac papillary fibroelastomas are the second most common primary cardiac tumor. This tumor is usually benign and it involves the cardiac valve. However, most cardiac papillary fibroelastomas originate from a single site, and the incidence of cardiac papillary fibroelastomas originating from multiple sites is very rare (5%). A 55-year-old woman who presented with momentary dizziness and syncope was evaluated by performing echocardiography. Multiple tumors attached to the aortic valve were noted. The mass was removed freely without leaving any defect on the aortic valve leaflet. After the recovery period, the patient is currently being followed up at the outpatient department.

The coexistence of mesenchymal tumor and carcinoma in the esophagus is extremely rare. We report a case of squamous cell carcinoma located at the mucosal surface over leiomyoma of the esophagus. A 76-year-old man with complaints of 3 months onset of odynophagia was diagnosed preoperatively as squamous cell carcinoma over submucosal tumor with calcification. Esophagectomy and esophagogastrostomy were performed through the right thoracotomy and upper median laparotomy. The patient is doing well without evidence of recurrence in the 25 months after resection. We discuss the pathogenesis and possible relations between the two tumors.

Primary leiomyosarcoma of the mediastinum is an extremely rare tumor that develops either in the mesenchymal cells of the visceral mediastinum or in the smooth muscle of the great vessels. In the literature, the most significant factor for determining survival is the ability to completely resect the tumor. But there is 30~64% recurrence rate and there is also a lack of data for the role of adjuvant therapy after complete resection. We report here on a case of recurred leiomyosarcoma of the mediastinum that was surgically removed via left thoracotomy 2 years previously and this was misdiagmosed as benign disease.

Posttraumatic psoudoaneurysrns of the subclavian artery are very rare. A 49-year-old woman who had been involved in a car accident ten years before presentation was initially diagnosed with a mediastinal tumor at a local clinic. Exploratory thoracotomy was performed for evaluation and treatment. During the operation, a hematoma was evacuated, and primary repair was undertaken to stop massive bleeding. Computed tomography angiography revealed a pseudoaneurysm of the left subclavian artery. The patient was treated with aneurysmectomy and end-to-end anastomosis. The postoperative course was uneventful.
