Recently, primary lung cancer has increased markedly in incidence and prevalence in Korea. From January 1986 to June 1993, 86 patients were operated and evaluated at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The results are as follows; 1. There were 79 males and 7 females with the peak incidence of 5th and 6th decades of life[75.6% . The age ranged from 13 to 76[mean 56.6$\pm$10.3 years. 2. Symptoms were cough[47.7% , sputum[25.6% , chest pain or dyspnea[18.6% , and hemoptysis or blood tinged sputum[20.9% in order. Symptoms were frequently encountered before hospitalization, but asymtomatic patients were 12.8% in this study. 3. Methods of diagnostic confirmatiom were bronchoscopic biopsy[55.8% , percutaneous needle aspiration[29.1% , suspicious sputum cytology[1.2% , and open biopsy[14.0% . 4. Histopathologically, squamous cell carcinoma[51.2% was the most frequent cell type and adenocarcinoma[26.7% , large cell carcinoma[8.1% , adenosquamous cell carcinoma[3.5% , and the others in order. And TNM stages were Stage I 40.5%, Stage II 15.5%, Stage IIIa 27.4%, and Stage IIIb 3.6%. 5. Methods of operation were pneumonectomy[25.6% , bilobectomy[5.8% , lobectomy[53.4% , segmentectomy[1.2% , and exploration[14.0% . The overall resectability was 86.0% 6. The operative mortality was 2.3% and postoperative complications developed in 7 cases[8.1% . 7. The postoperative follow-up reveals that the overall cumulative survival rates at 1 year, 2 year, 3 year, 4 year, 5 year were 76%, 62%, 43%, 36%, and 27%, respectively.

Herpes simplex virus pneumonia in immunocompromised host is difficult to diagnose with non-invasive method, and has high mortality rate. Because early diagnosis and early treatment can significantly decrease the mortality rate, the enthusiastic efforts for the early diagnosis should be done. A 41-year-old woman who took prednisolone due to mixed connective tissue disease developed gradually increasing dyspnea with radiological features of interstitial lung disease. Initially, we treated her with empirical antibiotics, but failed to improve her dyspnea. So we performed bronchoalveolar lavage and open lung biopsy. Open lung biopsy specimen showed herpes simplex virus pneumonia. Herpes simplex virus was also isolated from bronchoalveolar lavage fluid. There was both clinical and radiological improvement after treatment with acyclovir for 14 days.

We carried out a prospective study of the effectiveness of a diagnostic strategy in thirty consecutively seen patients who had skeletal metastasis. The diagnostic strategy consisted of the recording of a medical history, physical examination, routine laboratory analysis, plain radiography of the involved bone and chest, whole-body technetium-99m-phosphonate bone scintigraphy, abdominal ultrasound, computed tomography of the chest, abdomen and pelvis, fiberbronchoscopy and fibergastroscopy. After this evaluation, a biopsy of the most accessible osseous lesion was done in twenty four patients. On the basis of the our diagnostic strategy, we were able to identify the primary site of the malignant tumor in nineteen patients(63%). The laboratory values were non-specific in all patients. The history and physical examination revealed the occult primary site of the malignant tumor in one patient(3.3%) who had carcinoma of the breast. Plain radiographs of the chest established the diagnosis of carcinoma of the lung in three patients(9.9%). Computed tomography of the chest identified an additional three primary carcinoma of the lung(9.9%). Fiberbronchoscopy identified an additional one primary carcinoma of the lung(3.3%). Abdominal ultrasound established the diagnosis in three patients(9.9%). Computed tomography of the abdomen and pelvis established the diagnosis in four patients(13.2%). Fibergastroscopy established the diagnosis in two patients(6.6%). Examination of the biopsy tissue established the diagnosis in one patient(3.3%). So we recommend to perform plain radiographs of chest, abdominal ultrasound, chest C-T, abdomino-pelvic C-T, fiber-bronchoscopy, fibergastroscopy sequentially.
Many disorders and abnormalities are accompanied by cavitary lesoin of the lung and one of the most common causes of cavitary lung disease are primary and metastatic lung neoplasms. but cavitary formation of primary lung cancer is not frequent and cavitary or cystic pulmonary metastases of this is also rare. We report a case of cavitary pulmonry metastases of primary lung cancer proven by bronchoscopic biopsy and chest CT. The patients was 60 year-old heavy smoker who had no known underlying lung diseases 7 years ago and complained chronic cough. The chest CT showed primary lung cancer in right low lobe with multiple cavitary or cystic metastases in both lungs and multiple lymphatic metastases.

Primary lung lymphoma is an uncommon tumor, which constitutes 0.5% of primary lung cancer, and 3% of extranodal lymphoma. The most frequent radiologic presentation of pulmonary parenchymal lymphoma is single mass or nodule. But we have experienced a case which was radiologically presented as patchy lung infiltration at first, and then progressive multiple reticulonodular infiltrations in lung. A 48-year-old woman was admitted to the hospital because of fever and cough. Chest PA obtained on admission revealed multiple patchy infiltration. Eventually, open lung biopsy was performed and the specimen disclosed extranodal NK/T cell lymphoma, and in bone marrow aspiration, hemophagocytosis was present. We report a case of primary extranodal NK/T cell lung lymphoma presented as patchy lung infiltrations, which was treated with chemotherapy.
Pulmonary alveolar proteinosis is characterized by the accumulation of PAS positive lipoproteinaceous or amorphous proteinaceous material in the alveolar space with spared delicate septal architecture of the lung interstitium and impaired gas exchange of alveoli. We experienced a case of secondary pulmonary alveolar proteinosis in a 41 year old male patient who have occupational history of engagement as a mason over 4year. He compalined exertional dyspnea and chest discomfort, and presented fine inspiratory crackle at both lower lung field, numerous fine nodular denisties in both lung field with peripheral sparing. Light microscopic finding of lung tissue obtained by transbronchiallung biopsy revealed homogenous eosinophilic colloid-like luminal content in the alveolar space, and electron microscopy of bronchoalveolar lavage fluid concentrate showed electron-dense multilamellated structures. To treat the disease, we tried whole lung lavage of right lung with isotonic saline under general anesthesia. After whole lung lavage of right lung, he showed markid improvement of symptom and partial improvement of chest X-ray findings. The patient has been followed for 12 month until now, with no evidence of aggravation.
Background: Hyperinflation during lung ischemia has been known to improve pulmonary functions after reperfusion which may be exerted through a pulmonary vasodilation and avoidance of atelectasis by an increased surfactant release and been known whether the improvement of pulmonary function was the effect of hyperinflation itself or the oxygen content in inflation gas. Therefore we attempted to clarify the effect of hyperinflation with oxygen in pulmonary inflation gas during warm ischemia on pulmonary function after reperfusion to solve the problem of ischemia-reperfusion injury after lung transplantation. Material and Method: sixteen mongrel dogs were randomly divided into two groups: the left lung was inflated to 30-35 cm H2O with 100% oxygen in oxygen group and 100% nitrogen in nitrogen group. The inflated left lung was maintained with warm ischemia for 100 minutes. Arterial and mixed venous blood gas analysis and hemodynamics were measured before ischemia and 30, 60, 120, 180 and 240 minutes afer reperfusion. Lung biopsy was taken for the measurement of lung water content after the end of reperfusion. Result: In oxygen group arterial oxygen tension the difference of arterial and mixed venous oxygen tension and the difference of alveolar-arterial oxygen tension at 30-minute after reperfusion were not significantly different from those before ischemia and were stable during the 40hour reperfusion. However in nitrogen group these values were significantly deteriorated at 30-minute after reperfusion. there was no significant difference between two groups in hemodynamic data peak airway pressure and lung water content. Conclusion : The results indicated that the oxygenation one of the most important pulmonary functions was improved by pulmonary inflation with 100% oxygen during warm ischemia but the hemodynamics were not. Oxygen as a metabolic substrate during warm ischenia was believed to make the pulmonary tissues to maintain aerobic metabolism and to prevent ischemic damage of alveoli and pulmonary capillary.

Background: A chest computed-tomography has become more prevalent so that it is more common to detect small sized pulmonary nodules that have not been found in previous simple chest x-ray. If those detected nodules are undersized or located in pulmonary parenchyma, it is difficult to accomplish a biopsy since it is vulnerable to explore them either grossly or digitally. Thus, in our hospital, a thoracoscopic pulmonary wedge resection was performed after locating a lesion by means of hook wire with CT-guided. Material and Method: 31 patients (17 males and 14 female patients) from December in 2006 to June in 2010 became our subjects; their 34 pulmonary nodules were subjected to the thoracoscopic pulmonary wedge resection after locating a lesion by means of hook wire with CT-guided. Also we analyzed a possibility of hook wire dislocation, a frequency of conversion to open thoracotomy, time consumed to operation after location of a lesion, operation time, post operation complication, and histological diagnosis of the lesion. Result: 12 of 34 cases were ground glass lesion, whereas 22 cases of them were solitary pulmonary lesion. The median value of the lesion was 8mm in size (range: 3 to 23 mm), while the median value was 12.5 mm in depth (range: 1 to 34 mm). The median value of time consumed from location of the lesion to anesthetic induction was 86.5 minutes (41~473 minutes); furthermore the mean value of operation time was 103 minutes (25~345 minutes). Intrathoracic wire dislocation was found in one case, but a target lesion was successfully excised. Open thoracotomy was performed in four cases due to pleural adhesion. However, there was no case of conversion to open thoracotomy due to failure to detect a target lesion. In histological diagnosis, metastatic cancer were found in 15 cases, which were the most common, primary lung cancer were in 9 cases, non-specific inflammation were in 3 cases, tuberculosis inflammation were in 2 cases, lymph nodes were in 2 cases, active tuberculosis were in 1 case, atypical adenomatous hyperplasia was in 1 case and normal lung parenchymal finding was in 1 case, respectively. Conclusion: In our hospital, in order to accomplish a precise histological diagnosis of ground-glass lesion and pulmonary nodules in lung parenchyma, location of pulmonary nodules were exactly located with hook wire under chest computed-tomography, which was followed by lung biopsy. We concluded that this was an accurate, minimally invasive and valuable method to minimize the complications and increase of cost of medical service provided.
Systemic lupus erythematosus frequently has thoracic involvement among connective tissue diseases. One of the pleuropulmonary manifestations is diffuse interstitial lung disease including nonspecific interstitial pneumonia(NSIP). NSIP is a newly classified disease among interstitial lung diseases. Systemic lupus erythematosus has a better prognosis than usual interstitial peumonia(UIP) and responds well to steroids. In this report, a 34 year-old woman who complained of a dry cough, and exertional dyspnea for 2 months is described. The chest X-ray showed fine reticular opacities and a mild honeycomb appearance in both basal lungs. High resolution computed tomography(HRCT) showed bilateral patchy areas of ground-glass attenuation and a mild honeycomb appearance in the subpleural of both the lower and the middle portion of the lung fields. An open lung biopsy showed prominent lymphocytic interstitial inflammation and fibrosis with small areas with a honeycomb appearance. This case was diagnosed as NSIP associated with systemic lupus erythematosus and was managed with oral steroids. Here we report a case of nonspecific interstitial pneumonia associated with systemic lupus erythematosus confirmed by HRCT and an open lung biopsy with a review of the relevant literature.
Background: Video-thoracoscopy is known to be an useful method to provide accurate pre-resectional staging in patients with lung cancer in addition to the conventional radiologic studies and mediastinoscopy, for the pleural cavity is inspected directly and biopsy specimens call be obtained. This study is undertaken to evaluate how video-thoracoscopy can be used in deciding pre-resectional stage Material and Method: Video-thoracoscopy was performed in patients with lung cancer who were scheduled for surgical resection based on the radiologic staging and mediastinoscopic biopsy. 37 patients were included in this study. Pre-thoracoscopically 18 cases were in TNM stage 1, 7 in stage 2, and 12 in stage 3. Result: In 15 of 37 cases, video-thoracoscopy could not be performed effectively due to heavy adhesions in the pleural cavity, diaphragmatic and chest wall invasion of tumor and bulky tumor mass es. Mediastinal lymph nodes were positive postresectionally in 6 of these 15 cases. In 22 cases, video-thoracoscopy was performed as usual. Positive mediastinal lymph nodes were identified in 2 cases and exploratory thoracotomy was prevented. Surgical resection were carried out in remaining 20 cases and 5 cases among them had positive mediastinal lymph nodes. Conclusion: We believe that it is difficult to perform pre-thoracotorny video-thoracoscopy for all lung cancer patients for there were many cases that thoracoscory could not be undertaken doe to heavy adhesions in the pleural cavity, tumor involvement of the chest wall and/or diaphragm and bulky tumor mass. However we think it is helpful in preventing unnecessary exploratory thoracotomy for some patients with lung cancer whom pre-thoracotomy video-thoracoscopy was carried out.
