A 45 year old man was admitted for further examination of an abnormal shadow of the right posterior mediastinum. The patient suffered from dysesthesia in the right thoracic wall of dermatome T7. CT scan and MRI revealed that two separate tumors had developed in the right paravertebral area linked to the vertebral canal via an intervertebral foramina. One-stage removal of the tumors were performed safely through the right posterolateral thoracotomy following the resection of the rib head and vertebral pedicle. The tumors were confirmed as histologically neurilemomas. The postoperative course was uneventful.

Primary malignant melanoma of the mediastinum is extremely rare : To date, there have been only 8 cases reported in the literature. We report a case of a 50-year-old woman presented with an anterior mediastinal mass. The mass invaded the lung parenchyme of right upper lobe, which was wedge-resected with the mass. Microscopically, spindle or polygonal tumor cells with prominent nucleoli and intracytoplasmic melanin pigments are characterized and Fontana stain confirmed the presence of melanin pigment. Immunohistochemical studies showed diffuse positive staining for HMB45, S100 protein and vimentin, which further suggested melanoma.

흉막의 고립성 섬유성 종양은 중피하에 존재하는 미분화 중배엽성 기원의 섬유 세포에서 기원하는 종양으로 알려졌다. 이 종양은 대부분 양성으로 보고되고 있으나 병리학적으로 높은 세포 밀도, 유사분열의 수가 많고(10개의 고배율 시야에서 4개 이상), 핵의 다양성, 출혈, 괴사등이 있으며 악성의 판단기준으로 보고된다. 환자는 62세 여자로 호흡곤란 및 기침을 주소로 본원에 입원하였으며 단순 흉부 방사선 및 전산화 단층 촬영상 우측 흉강내에 거대한 종양소견이 보였다. 이 종양은 23$\times$18$\times$12 cm, 2 kg의 크기와 무게를 가졌으며 우측폐 하엽과 중엽은 압박되어있었으나 종양 절개 후 재 팽창됨을 확인하였다. 또한 횡경막과 심하게 유착되어 박리도중 손상이 동반되어 봉합술이 필요하였다. 병리학적으로 종괴는 세포밀도가 높았고 방추형세포의 다발로 이루어져 있었으며 유사분열의 수가 많이(27 mitosis/10HPF)보였다. 면역 조직 화학 검사상 vimentin과 CD34에 양성 반응을 보였다. 이에 악성 고립성 섬유성 종양으로 확진되었다. 본 교실에서는 흉막에 발생한 악성 고립성 섬유성 종양을 치험하였기에 문헌 고찰과 함께 보고한다.

Lymphangioma(or cystic hygroma) of the chest wall is rare case. We experienced one such case in a 16-year-old girl who complained of a large recurrent mass on her right upper post erolateral chest wall which had developed several years ago. The diagnosis was made following a physical examination, chest magnetic resonance imaging(MRI), and radio isotope (RI) lymphangiogrphy and was confirmed by a histopathological examination. We performed total excision of the lesion followed by a repeated sclerosing therapy with intralesional injection of Vibramycin.

Primary cardiac tumor has very low incidence, especially in cases of malignancy. A 29 year old male patient visited our cardiologic clinic for recent aggrevation of dyspnea on exertion and palpitation. Echocardiography showed a large tumor in the left atrium, which suggested the left atrial myxoma. Urgent open heart surgery was taken. The operative finding was fossa ovalis based a large tumor (35$\times$90$\times$50 mm) that invaded the posterior wall of LA and right superior pulmonary vein directly. The tumor was excised well by simple dissection, and the final pathologic report was malignant myxofibrosarcoma. His postoperative course was smooth and he was discharged in good health. Postoperative radiation and chemotherapy had taken with satisfactory clinical outcome.

The incidence of a pulmonary leiomyosarcoma as a primary lung tumor is quite rare. We report a case of primary leiomyosarcoma with a cardiac invasion in a 76 year old man. He was admitted due to left anterior chest wall pain for one month. Chest computed tomography showed a $9{\times}8{\times}10cm$ sized, large round mass in the left upper and lower lobes, and an amorphous low density lesion within the left atrium. Chest magnetic resonance imaging showed a large round mass in the left upper and lower lobes with growth into the left atrium. A diagnosis of leiomyosarcoma with prominent osteoclast-like giant cells was made based on the microscopic and immunohistochemical findings of a permanent specimen by explothoracotomy. The pathologic features of the tumor showed round mononuclear hyperchromatic cells and multinucleated giant cells that resembled osteoclasts. The immunohistochemical staining showed that the giant cells are positive for CD68 but negative for the muscle markers while the round cells were positive for the muscle marker. The patient refused further treatment and died after two months.

A 64 year-old woman presented to out hospital because of syncope. Transesophageal echocardiography showed a $4.2{\times}2.4\;cm$ hypervascular mass in the left atrium. We assessed the mass to be a myxoma and we planned to excise the mass. The preoperative coronary angiography showed a feeding artery with an inner diameter of 2mm originating from the left circumflex coronary artery, so we excised the mass and clipped the feeding artery with two clips at the epicardium with a good result.

Pulmonary hamartoma is a common benign tumor of the lung, but endobronchial hamartoma is a rare tumor. Although bronchoscopic rcemoval or removal by bronchotomy or sleeve resection with preservation of the lung may be possible, when irreversible lung damage has occurred because of chronic obstruction and pneumonitis, pulmonary resection may be indicated. We herein report a case of endobronchial hamartoma which was treated by left upper lobectomy. A 42-year-old female with 3-week history of cough and left chest pain visited our hospital. Bronchoscopy showed total occlusion of the orifice of the left upper lobe bronchus by a lobulated endobronchial tumor and bronchoscopic biopsy was failed due to bleeding. A left upper lobectomy was performed because of severe consolidation of the left upper lobe by chronic obstruction. The patient was discharged on postoperative 14th day.

A 44-year-old man had been admitted for dyspnea on exertion and abdominal distension. The echocardiography revealed abnormal mass in right atrium and tricuspid valve stenosis with right ventricular obliteration. The operation was performed with mass removal, enlargement of tricuspid valve opening, and right ventricular endocardiectormy. And then, atrial septal defect was made due to inadequate right ventricular volume. The patient's symptom was improved and he discharged without events. The endomyocardial fibrosis was diagnosed with microscopic examination. Eighteen months later, the patient was readmitted due to aggravated dyspnea and cyanosis. The right ventricular obliteration was progressed and pulmonary blood flow was severely decreased in follow up echocardiography. Palliative bidirectional cave-pulmonary shunt was performed due to functional single ventricle. The dyspnea and cyanosis was markedly improved. Bidirectional cavo-pulmonary shunt for advanced and isolated right ventricular endomyocardial fibrosis provided effective palliation at early postoperative period, However, long-term follow up is mandatory.

Lymphangioma is a developmental anomaly that is known to occur in the neck and axilla, and only rarely in the mediastinum, retroperitoneum, groin and pelvis. An isolated chest wall lymphangioma is a rare benign neoplasm. In case of large sized lymphangioma, surgical excision is preferably recommended as the treatment of choice. We operated on a three-year old female for excision of chest wall. In pathologic diagnosis, it diagnosed the mass as chest wall lymphangioma.
