Eighty-four-year old man who had lapalotomy for stomach ulcer perforation 35 years ago was admitted for left lower chest discomfort. Chest X-ray and CT showed a large mass with air fluid level in left lower lung field. The tentative diagnosis was infected bronchogenic cyst. After a thoracotomy, the mass was confirmed as elevated diaphragm and subphrenic abscess with a foreign body, retained surgical gauze. The pus and gauze were located between stomach and diaphragm. His hospital course was smooth and uneventful, he was discharged with good outcome on postoperative day 9.

Primary malignant melanoma of the lung is extremely rare. A 46-year-old lady was admitted with two month history of dry cough and blood-tinged sputum. Chest CT showed 4.5 $\times$ 5.0 cm sized mass at the right lower lobe. Repeated bronchoscopic and percutaneous biopsies showed no definite diagnosis. Preoperative evaluations revealed no systemic metastais. So, we tried the surgical approach. Right lower lobectomy and lymph node dissection was done. The mass and lymph node were confirmed as primary malignant melanoma. The patient presented with right hemiparesis 40 days after operation. Brain MRI showed 1.5$\times$2.0 cm sized mass lesion on the left parietal lobe. Mass excision was done. However, she expired 8 months later.

Gastrointestinal stromal tumor is documented on every part of the gastrointestinal tract. It develops in the stomach and the small intestine most commonly, and also in the esophagus. A 44 year-old male patient was admitted due to dysphagia and weight loss. Chest CT showed about $15\times11\times11cm$ sized, well-defined, and lobulated soft tissue mass with central necrosis was noted in the posterior wall of lower esophagus throughout the lesser curvature of upper stomach. We performed the distal esophagectomy and total gastrectomy using thoracoabdominal incision. The tumor was positive at CD117 (c-kit) and CD 34, and was diagnosed as malignant GIST of the distal esophagus and upper stomach. The patient is on routine follow up at the out patient department for nineteen months up to now.

"Middle lobe syndrome" which was described y Graham and associates at first is always caused by ex- ternal bronchial compression by Iymph nodes. Although the patients may not present any symptom, the most common presenting symptoms were cough, dyspnea, fever, hemoptysis, and chest pain. Diagnostic procedures includ chest X-ray bronchoscopy, brochography, chest CT, and the principal finding is the contracted middle lobe which is usually airless. We experienced fifteen cases of middle lobe syndrome from April 1990 to May 1995. Eleven patients were treated surgically. The surgical candidates for middle lobe syndrome are suspicious malignancy, fixed bronchiectasis, bronchostenosis, intractable to medical treatment, recurrent infection. Operations were right middle lobectomy (8), right middle and lower bilobectomy (2), right upper and middle bilobectomy (1). Postoperative histological findings were tuberculosis in six, chronic inflammation in three, malignancy in one, and focal hemorrhage in one. There were two cases of postoperat ve complications which were postoperative atelectasis and hepatopathy.patopathy.

Malignant mesothelioma has been considered a uniformly fatal disease associated with a median survival of 4 to 18 months. However, a multimodality approach toward therapy may Increase the length of palliation when a maximal resection of tumor is achieved. Recently we have experienced a 49 years-old male patient who had d ffuse malignant mesothelioma. The patient has complained of blood-tinged sputum and right chest pain for several months. Chest x-rays and CT scans showed compact haziness in the right entire thorax with massive bloody elusion, diffuse pleural thickening and collapsed underlying lung. We performed extrapleural pneumonectomy, and postoperative chemotherapy with cisplatin and mltomycin (Memorial Sloan-fettering Cancer Center method) was done. We are observing him for months now and there is no evidence of local recurrence.

Among the causes of SVC syndrome, intraluminal tumor, especially the leiomyosarcoma is very rare. We report a 39 year old female patient who had been suffering from headache and facial edema for 6 weeks before admission. On physical examination, facial edema and venous engorgement on upper extermities and upper chast wall were showed. The chest CT scan and SVC cavogram showed a long intraluminal mass lesion resulting in a near total obstruction of the SVC Surgery was performed through median sternotomy. For complete resection of the tumor and thrombus, we used partial and total CPB. The follow up SVC cavogram revealed no abnormality 14 months after the operation.

Mediastinal lipoblastoma is a rare benign tumor originating from embryonic lipid cells and it almost always occurs during infanthood or early childhood. It is a tumor with a good prognosis despite its potential for local invasion and rapid growth. We report here on a three years old girl who was treated for a benign lipoblastoma in the anterior mediastinum. CT scanning showed a fat containing mass without internal calcification or fluid component, and the mass showed a compressive effect on the adjacent structures. The mass was located between the pericardium and right mediastinal pleura and it was removed completely without complication. Pathologic examination revealed a benign lipoblastoma. The patient showed no evidence of recurrence at the time of the report.

A 55-year-old male presented with intermittent cough and blood-tinged sputum. 35 years earlier in the Army Armed Forces, he had undergone lung surgery of the right upper lobe because of tuberculosis. Chest CT showed a mass-like lesion with an internal air-meniscus sign in the right lung. The mass was $5{\times}7\;cm$ in the right upper lobe and it was a well marginated lesion. The resected mass contained a foreign body, that is, a retained surgical gauge. Herein we report on a rare case of retained gauze after surgery that mimicked aspergilloma.

A 59-year old female patient was admitted due to massive hemoptysis. 6-months previously, we performed ascending aorta graft interposition for terating Debakey type 1 acute aortic dissection. Chest CT scan showed the fistula between the descending thoracic aorta and the left lower lobe. We performed descending thoracic aorta graft interposition under cardiopulmonary bypass. She recovered well without any postoperative problems. Distal aorto-bronchial fistula after a previous aortic operation is very rare. We report here the good results of treating aorto-bronchial fistula because we recognized this lesion early and performed an early operation.

Pulmonary sequestration and congenital cystic adenomatoid malformation are two infrequent congenital pulmonary diseases and the combination of these two entities is rare. We had experienced a 3 week old male patient with a pulmonary mass, who had been sufyerring from tachypnea and chest wall retraction after birth. The pulmonary mass was suspected as a congenital cystic adenomat id malformation by chest CT. And therefore, we performed urgent operation via standard thoracotomy incision. Upon a thoracotomy, there was an extrapleural mass with anomalous blood supply near the posterior diaphragm and multiple cystic lesions in right lower lobe. The two anomalous arteries arising from the thoracic aorta and one vein draining into the azygos vein were ligated. and then the extrapleural mass was removed and a right lower lobectomy was performed. Final histologic diagnosis was congenital cystic adenomatoid malformation associated with extralobar pulmonary sequestration. The patient was discharged without any problem.
