Materials and methods: Between 1979 and 1996, 27 patients with primary cardiac tumor underwent surgery at Catholic University Medical College. Mean age of patient was 45.1${\pm}$3.03 ranging from 21 to 67 years old. Twenty-four cases were myxomas, 2 cases were chondrosarcoma, and remained case was angiosarcoma. Diagnosis was confirmed by echocardiography, cardiac angiography, CT scan, and MRI. The most common site of tumor origin was fossa ovalis limbus area(17cases:63%). A biatrial operative approach was commonly used in 15 cases and the tumor was removed through left atriotomy site. Complete excision of the tumor with a cuff of normal tissue was performed. All heart chambers were carefully explored for evidence of multicentric myxomas or other tumor debris. Most of the patients were improved on postoperative period compared to preoperative NYHA functional class. Results: There was one operative death due to low cardiac output syndrome. Follow up period was 3 months to 17 years. There was 2 late deaths due to local recurrences. Conclusion: complete surgical excion is important for increasing cure rate. Malignancy cannot be ruled out even though preoperative echocardiography suggests benign nature. Chest CT or MRI is effective for further evalution in addition to echocardiography. In suspicious of malignancy, more extensive resection is essential and postoperative chemotheraphy or radiotherapy is useful.

Most tumors of the tracheobronchial tree are malignant, and benign tumors are less than 10%. Especially, the incidence of primary neurogenic tumors of the lung has been estimated to be less than 2 percent of primary lung cancer, and majority of these tumors are originated from Schwann cells. These tumors can be presented either as a solitary benign neoplasm or as a malignant form, which is rare. We present two cases of bronchial Schwan noma managed by means of lobectomy.

Mucoepidermoid carcinoma is an uncommon lesion that accounts for approximately 1% of primary malignant bronchial gland tumors and less than 0.2% of all lung neoplasm. This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is uncommon, therefore complete surgical resection is the treatment of choice. The prognosis of tumor correlates with on the histologic grade of tumor. We experienced mucoepidermoid carcinoma in a 15 year-old girl with symptoms of cough and blood tinged sputum. The patient underwent successful removal of tumor by bilobectomy via explorothoracotomy after chest CT and bronchoscopic biopsy.

심장에서 발생하는 모셀혈관종은 극히 드문 양성 종양이다. 본원에서는 호흡곤란을 주소로 내원한 13세 남자 환자에서,심포음파상 중등도의 혈류 폐쇄를 초래하는 우심실내 종괴를 확인한 후, 우심방을 통해 완전 절제하여 조직검사상 모세 혈관종을 발견하였기에 문헌고찰과 더불어 증례보고하는 바이다.

A 60-year-old male was admitted because of dyspnea and angina like chest pain. Noninvasive findings showed a mass at the posterior aspect of the left atrium. The mass was removed under cardiopulmonary bypass. An encapsulated adipose mass, which originated from the left atrium without any invasion to the pericardium, was completely excised. Histological examination showed mature adipose tissue with partial necrosis, confirming the diagnosis of lipoma. We report a rare of case of massive left atrial lipoma occupying the pericardial space.

The neuroendocrine tumor is a rare thymic neoplasm, which has been regarded as a distinct tumor from thymoma and originates from Kultschizky cell. The pathologic diagnosis of thymic neuroendocrine tumor has been on findings from light microscopy, immunohistochemical studies, and electron microscopy. About 50% of thymic carcinoids are seen with endocrinopathies. Recurrence and extrathoracic metastasis are characteristics of thymic carcinoids. Surgical removal of the initial and recurred tumor is considered to be the most effective treatment. The role of the adjuvant chemotherapy and radiotherapy is still uncertain. Herein we report a case of thymic neuroendocrine tumor, which was resected surgically.

Mucoepidermoid cancer of the bronchus in childhood is extremely rare. These tumors generally produce symptoms of airway obstruction, often misdiagnosed as unresolved tuberculosis. Distant metastasis is an uncommon finding of this malignancy, therefore complete surgical resection is treatment of choice. The prognosis of these tumors correlates with the histologic grade of the tumor. We report our clinical experience of mucoepideromoid cancer in a 10-year-old child who visited our hospital with symptoms of recurrent cough and fever. The patients underwent successful removal of tumor by bilobectomy via thoracotomy after bronchoscopic biopsy.

Cardiac hemangioma is an extremely rare benign tumor. A 65 years old woman was admitted due to epigastric and chest pain, After we confirmed cardiac tamponade with right atrial mass by chest CT, we performed surgical resection of the mass and identified hemangioma with capillary endothelial hyperplasia on pathologic examination. Therefore, we report the case with literature review.
