Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Intravenous leiomyomatosis is a rare tumor that originates from the uterus and spreads through the vessels. Although histologically benign, tumor extension with mechanical obstruction of the inferior vena cava, right cardiac cavities, or even the pulmonary artery, may occasionally result in fatal outcome. The best treatment is complete surgical resection of the entire tumor using cardiopulmonary bypass and total circulation arrest, We report a case of intravenous leiomyomatosis of the uterus that showed intravascular growth up to the right atrium. The patient underwent successful resection of the tumor by one-stage cardiotomy with laparotomy.

We have experienced 44 cases of coarctation of aorta in the age of infancy and children from April 1986 to September 1989 at Seoul National University Children`s hospital. Patients were thirty males and fourteen females, and their age ranged from one month to ten years[mean 23.84 $\pm$33.06 months] with thirty-two infant cases. In the infantile age, congestive heart failure was the most common chief complaint[18/32], and above that age, frequent upper respiratory infection was most common[8/12]. We experienced thirteen cases of isolated COA, twenty-two cases of COA with VSD, eight cases of COA with VSD, eight cases of COA with intracardiac complex anomalies and one case of COA with atrial septal defect. The associated intracardiac complex anomalies were three Taussig-Bing type double outlet right ventricle, one single ventricle, one transposition of great arteries, one atrioventricular septal defect, one hypoplastic aortic arch with left heart hypoplasia, and one Tetralogy of Fallot. Operative techniques of COA were twenty-three subclavian flap arterioplasty, 12 resection and end to end anastomosis, eight onlay patch angioplasty, and I direct angioplasty after resection of web. Among the cases with other cardiac anomalies, staged operation was done in twenty-nine patients, and single stage total correction was performed only in three patients. There were seven operative mortality[15.9%], all being in infantile age group, and among fourteen cases associated with large VSD[Qp/Qs>2.0, mean pulmonary arterial pressure>50mmHg], four patients were died, but there was no mortality in patients with small VSD. With above results, we are intended to discuss about the interval between staged operation, the fate of VSD after coarctoplasty in case of COA with VSD, causes of death, complications etc.

Primary leiomyosarcomas are rare tumors of the lungs. No typical roentgenographic findings of unusual complex of symptoms distinguish this tumor. The most common therapy is surgical resection. Prognosis and significant survivorship are related to the size, grade, metastasis of the lesion. A 25-year-old female patient with chest pain and cough was admitted. In chest X-ray and CT scan, there was a pulmonary nodule in left upper lung field, She was taken a percutaneous needle aspiration biopsy. The result was a spindle cell tumor. Left upper lobe lobectomy was done, and pathologic diagnosis was a low grade leiomyosarcoma arising from left bronchus. During 5 years of follow-up period, she has not shown any metastasis or local recurrence.

The pulmonary giant cell carcinoma is classified as a variant of a large cell carcinoma and is diagnosed by the minimum component of 10% huge, pleomorphic and multinucleated giant tumor cell and emperipolesis of the neutrophils into the tumor cells. This tumor is characterized by local recurrences and early metastasis with extremely short patient survival. However, there are some reports that state that the survival time was extended by the operative resection and postoperative adjuvant chemotherapy and radiotherapy. A 46-year old male was admitted with complaint of hemoptysis for 2 months. Through chest X-ray and chest CT, a 5cm sized mass was found in the apical segment of the right upper lobe. During the preoperative evaluation, stenotic lesion in the left anterior descending coronary artery was found and treated by percutaneous transarterial coronary angioplasty. Four weeks later, right upper lobectomy was performed and the mass was proven to be a giant cell carcinoma. The patient received adjuvant chemotherapy and radiotherapy.

Endobronchial lipomas Are rare lesions that usually obstruct a major bronchus and cause irreversible pulmonAry damage distally. They are histologically benign tumors. But they can produce pulmonary damage or irreversible bronchiectasis if dignoses or tr atments are delayed. Whenever possible, the treatment of choice is resection by means of bronchoscopy. If endoscopic removal is not possible or lf the nature of the tumor is unclear, surgery is necessary. with lobectomy or pneumonectomy being required in most cases due to the extensively damaged pulmonary parenchyma . We present a case of endobronchial lipoma causing bronchial obstruction and peripheral organizing pneumonia with its clinical features. diagnosis find treatment methods.

Background: Patients with pyogenic lung abscess who do not respond to medical therapy are usually candidates for thoracotomy with pulmonary resection. Percutaneous tube drainage, used routinely and with good results before the antibiotic era, has nearly been forgotten. Methods: We treated 8 patients who had poor cadidates for a lobectomy and didn't respond to medical management. A pig-tail catheter (6 to 10 Fr.) was inserted into the abscess under the fluoroscopic guidance. Results: All patients brought about dramatic clinical responses with prompt closure of cavity and radiographic improvement. Conclusion: Percutaneous pig-tail catheter drainage provides excellent clnical results with ease and safety, and avoids unnecessary loss of functioning lung parenchyma. But lobectomy should be considered in patients who major life-threatening bleeding or massive pulmonary necrosis.

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor of borderline or low-grade malignancy, and its prognosis is unpredictable. Herein, we describe the case of a 47-year-old asymptomatic female with a diagnosis of multinodular PEH. During a 7-year follow-up, the nodules with large size and high ¹⁸F-fluorodeoxyglucose uptake in the initial study showed progression with increasing sizes; however, most small nodules (size < 1 cm) demonstrated spontaneous regression with peripheral rim or nodular calcification. The patient underwent surgical resection for an enlarged nodule. Of note, it is unusual for an individual to have mixed progression and regression concomitantly, which may be helpful in predicting the prognosis.

Background: Intralobar and extralobar pulmonary sequestrations have been considered as congenital lesions that occur at different stages of embryonic life. However, most cases of intralobar pulmonary sequestration (IPS) seem to have an acquired origin, as they are absent in infants and associated anomalies are relatively, uncommon among them. Material and Method: The cases of 25 patients who were diagnosed as IPS after surgical resection from December, 1985 to July, 2002 were included in this study. The medical records wire retrospectively reviewed and the clinical characteristics were age at operation; gender; symptoms at presentation; presence of congenital anomalies; combined diseases; preoperative studies and diagnosis; location of the lesion; method of surgical resection; origin, size and numbers of aberrant artery; histopathological findings; and postoperative complications. Result: There were 17 (68%) female patients and 8 (32%) male patients, their ages ranged from 1 to 57 and mean value was 23 years old. Though 14 patients (56%) complained of respiratory symptoms such as pneumonia and recurrent respiratory infections, a large number of patients (44%) were asymptomatic or had chest pain only when the lesion was discovered. Only 8 patients (32%) were diagnosed as pulmonary sequestration preoperatively and 8 (32%) were suspected as mediastinal or lung tumor, 5 (20%) were congenital or acquired cystic lung disease, and 4 (16%) were lung abscess or bronchiectasis, respectively. The majority of aberrant arteries (86.4%) confirmed during the operation were originated from thoracic aorta and 2 were thoracic and abdominal aorta, 1 was abdominal aorta, respectively. The younger patients (less than 10 years old) had more other congenital anomalies (30% vs 6.7%) but the proportion of congenital IPS was not significantly different (10% vs 6.7%, p>0.05) compared with elder patients. Histopathologically, almost all lesions showed chronic inflammation, cystic changes and similar pleural adhesions regardless of age. Conclusion: The large portion of the patients with IPS (44%) was clinically asymptomatic or presented non-respiratory symptoms at diagnosis and likely to be diagnosed as mediastinal or lung tumor especially in elder patients. Though the younger patients had more other congenital anomalies, most cases of IPS proved to be acquired lesions in terms of the histopathlogical findings and the proportion of congenital evidences.

We performed nerve resection and reconstruction of the phrenic nerve in a 63-year-old female patient who underwent complete resection of a malignant thymoma. The left phrenic nerve was completely encased by the tumor for 2 cm. Thus, a 3 cm long piece of phrenic nerve with 5 mm margins of safety on each end was resected and it was directly anastomosed in an end-to-end fashion. At 11 months after reconstruction, fluoroscopy demonstrated adequate and symmetric motion of both hemidiaphragms, which indicated the restoration of phrenic nerve function. The pulmonary function test results were comparable to those obtained preoperatively at 30 months. There has been no evidence of recurrence at the recent follow up visits.

Sixty patients with proven lung cancer were retrospectively studied to determine whether postoperative radiation therapy improves survival. Patterns of treatment failure and 5 year survival were assessed according to extent of tumor spread, histology, type of operation, positive resection margin and radiation dose. Of the 60 patients, excluding S patients who received incomplete treatment or poor pulmonary function,55 patients received postoperative radiation therapy following curative resection. The overall survival at 5 years was $39\%$. The hilar and mediastinal lymph node involvement had an influence on survival. The authors recommend that patients with resection. lung cancer involving the hilar and mediastinal lymph nodes may require postoperative radiotherapy to reduce the local recurrence and improve survival.
