The mediastinoscopy was a well known useful diagnostic tool for detection of certain mediastinal tumors ,mediastinal lymph nodes invasion by bronchogenic carcinoma and metastatic cancer. A total of 33 cases of mediastinoscopies were reviewed, which were experienced at Chon Buk National University Hospital from August,1980 to October 1991. Mediastinoscopy was performed through anterior or parasternal approach in 18 cases, cervical approach in 14 cases and both in 1 case. In 12 cases which were used for preoperative stagig of lung cancer, 10 cases[83.3%] had the positive biopsy results at mediastinal nodes. In 11 cases for diagnosis of lymph nodes and masses with unknown lung lesion, small cell carcinoma revealed in 3 cases,squamous cell carcinoma in 2 , adenocarcinoma in 1 case and the others were had the negative biopsy results. In 10 cases for diagnosis of mediastinal tumors, lymphoma revealed in 2 cases, malignant thymoma in 2, sarcoidosis in 2, tuberculous granuloma in 1, mesothelioma in 1, metastatic cancer with unknown origin in 1 case. Thoracotomy was performed in 3 cases of lung cancers, 2 patients with negative biopsy results in preoperative staging and 1 patient with subcarinal lymph node involvement only. Bleeding complications during mediastinoscopy were developed in 2 cases, managed by anterior mini-thoracotomy.

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.

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of tissues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen (PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy (LHRH agonist) was applied to this patient.

Background: Hemoptysis always merits thorough investigation because even minimal bleeding may be an early indicator of the presence of significant bronchopulmonary disease. But in patients with hemoptysis & a normal chest roentgenogram, there are no clear guidelines for a diagnostic approach, including the indications of bronchoscopy. Methods: Eighty patients with hemoptysis and a normal chest roentgenogram were involved in this study. We evaluated the cause of hemoptysis in these patients by bronchoscopy and/or bronchogram or high-resolution CT of the lung and we analyzed the relationship of clinical features, such as age, sex, smoking and properties of hemoptysis, to the cause of hemoptysis. Results: 1) They were 34 men and 46 women, with the mean age of 46.7 and 41.8 years old, respectively. 2) Initial bronchoscopy provided a diagnosis in 8 patients - bronchogenic carcinoma in 3 patients (3.8%), metastatic cancer in 1 patient(1.3%) and endobronchial tuberculosis in 4 patients(5.0%). 3) Two clinical findings of patients over 50 years and/or with more than 30 pack-year smoking history were associated with bronchogenic carcinoma, and among these two factors, a more than 30 pack-year smoking history was the best predictor for diagnosis of bronchogenic cancer. 4) The 72 patients in whom no specific cause of hemoptysis was identified by initial bronchoscopy underwent bronchogram and/or high resolutional CT of the lung. Then, 6 patients were diagnosed as bronchiectasis and 5 patients rebleeded in the follow up period of 9 to 90 weeks. Of the remaining 66 patients, 33 were followed for 7 to 80 weeks. Among these patients, only 5 patients had recurrent episodes of hemoptysis & they were diagnosed as bronchiectasis in 1 patient, tuberculosis in 2 patients and catamenial hemoptysis in 2 patients. Conclusion: We conclude that patients with hemoptysis and a normal chest roentgenogram who are more than 50 years old or have more than 30 pack-year smoking history should undergo bronchoscopy to exclude possible bronchogenic carcinoma. In patients without these clinical features, a conservative approach with observation appears justified. If hemoptysis recurs to these patients, bronchogram or high-resolutional CT of the lung with sputum examination are necessary.

Although exophytic endobronchial lesions can readily be diagnosed by routine forceps biopsy through the fiberoptic bronchoscope, submucosal or peribronchial tumor can be difficult to diagnose. So we evaluated the diagnostic utility of transbronchial needle aspiration (TBNA) through the fiberoptic bronchoscope in patients presenting with endoscopic abnormalities suggestive of submucosal or peribronchial tumor. Patients and Methods : Retrospective review of 120 lung cancer patients who were found to have the lesions suggestive of peribronchial and submucosal tumor during fiberoptic bronchoscopy was performed from Jan. 1994 to Dec. 2002 at Severance Hospital, Yonsei University College of Medicine. Results : Forcep biopsy was positive in 63 cases (52.5%) and TBNA in 91 (75.8%), which was significantly better than forcep biopsy (p=0.001). The combination of forceps biopsy and TBNA was positive in 106 cases (88.3%), which was significantly better than forceps biopsy alone (p=0.0001). The difference of TBNA yield according to cell type or bronchoscopic appearance of lesion was not significant, but it showed the relatively better result in small cell carcinoma. Conclusions : We concluded that TBNA significantly increase the yield over forcep biopsy alone in the detection of submucosal or peribronchial bronchogenic carcinoma.

Sleeve pneumonectomy can be a method of treatment in a selected patient with bronchogenic carcinoma involving carina. A 64 years old male with a history of mitral valve replacement via midsternotomy 13 years ago and resection of papilloma of the vocal cord 2 years ago. The patient was admitted due to blood-tinged sputum. Bronchoscopy and computerized tomogram of the chest revealed 3.5 cm mass at lower margin of the trachea and totally obstructing the left main bronchus. A biopsy revealed squamous cell carcinoma. He underwent left sleeve pneumonectomy through sequential bilateral thoracotomy without cardiopulmonary bypass, and the pathologic stage was T4N0M0 stage IIIB. The patient is being followed through the outpatient clinic in good general condition.

To evaluate the role of sputum and bronchial washing for the diagnosis of lung carcinoma, we studied the sensitivity of both cytologic techniques using the biopsy confirmed cases from 228 patients. Among them, 123 cases were squamous cell carcinomas, 42 cases were adenocarcinomas, 48 cases were small cell carcinomas, one case was large cell carcinoma, and 14 cases were other types of carcinoma including poorly differentiated carcinomas. Three hundreds and ninety two sputa and 173 sputa were obtained in the pre- and post-bronchoscopic periods. Bronchial washing had been taken once in each patient. The overall sensitivity of the sputum cytology was 0.52 and that of the bronchial washing 0.63, while it increased to 0.83 when a combination of both techniques. Squamous cell carcinomas were diagnosed to the great extent in which sensitivities were 0.59 and 0.74, in sputum and bronchial washing, respectively. The post-bronchoscopic sputa showed higher sensitivity (0.44) than pre-bronchoscopic sputa (0.30). The sensitivity on sputa increased from 0.34 to 0.49 when three samples were examined compared to the single examination. The accuracy of cell typing was 94.0% in sputa and 93.8% In bronchial washing. Repeated sputum examination including post-bronchoscopic sputa is warranted to Improve sensitivity and a complementary role of both cytologlc techniques can be postulated by these data.

This is a report of three cases of successful embolectomy in peripheral arteries. First case was the patient who received a mitral commissurotomy 8 months ago. In that time, there was no evidence of left atrial thrombosis. He showed an embolism in the middle portion of left brachial artery without complaining of any ischemic pain. Embolectomy was performed 15 days after disappearance of radial pulse and resulted in no return of radial pulse postoperatively. Second case was a case of an embolism in lower portion of right brachial artery. She complained severe ischemic pain and cyanosis in the right forearm and fingers. She was also in the beginning state of cardiac failure, which was suspected from her hypertension associated with cardiomegaly and arrythmia Embolectomy was performed 17 hours after onset of acute pain. Immediate full pulsation of radial artery was obtained after embolectomy and the acute ischemic symptoms subsided gradually. Third case was an embolism in superior mesenteric artery which occured 24 hours after pneumonectomy for right bronchogenic carcinoma and the patient suddenly complained diffuse abdominal colicky pain. 7 hours after attack of abdominal pain. embolectomy with extensive reset ion of the small intestine was performed with uneventful recovery and without complication, such as short bowel syndrome, postoperatively. Histopathologically, the embolus was consisted of a tissue of anaplastic cell carcinoma, which was identical to the tumor of the resected right lung. Histological findings of other emboli of first and second case were old thrombus.

The roentgenologic appearance of carcinoma of the lung may vary considerably from case to case. And when it forms cavitary lesion, it is frequently confused with benign lesions and treated conservatively. Twenty-seven patients with cavitary bronchogenic carcinoma were treated in our St. Marys Hospital during the period 1984-1989. There were 24 males and 3 females. They ranged in age from 43 to 76 years. Symptoms of cough, blood-streaked sputum or pleuritic chest pain were present in all patients one month to 6 months before hospital admission and 7 patients among them were delayed in recognition of the malignancy from z month to 3 months. Of 27 malignancies with cavity, 22[81.5 %] were squamous cell ca., 3[11.1%] were large cell ca., and 2[7.4%] were adenoca. And of 22 squamous cell carcinomas, 5 were well differentiated, 13 were moderately and 4 were poorly. All lobes except Rt. middle lobe were involved [RUL 2 cases, RLL 13 cases, LUL 3 cases and LLL 9 cases]. We explored 16 patients and performed 7 lobectomy, 4 bi-lobectomy, 2 pneumonectomy and 3 08zC. Post-operative follow-up examination of the resected 13 patients indicated one and two year survival rates of 69.1 %[9/13 cases] and 37.5%[3/8 cases] respectively, and now 6 survivors whose post-operative periods were from 4 months to 37 months.

A 31-year-old female visited O.P.D. of internal medicine, Kyung Hee Medical center, with the chief complaint of generalized weakness and headache. She took a routine chest P-A and there was a 6.5 x 7.5 cm sized round mass in the right middle lung field. She admitted to the Dept. of Thoracic and Cardiovascular Surgery under the impression of malignant bronchogenic carcinoma with the remit of bronchoscopy and sputum cytology and tomogram. Middle and lower lobectomy of right lung was performed and postoperative surgical biopsy revealed out the plasma cell granuloma. The plasma cell granuloma may occur as a solitary nodule in the lung or be associated with systemic disease, plasma protein imbalance, or nonspecific local inflammatory reaction . More than two third of the reported patients were less than 30 year of age. Grossly the lesion appears reddish-brown and microscopic features include pallisade or a cartwheel distribution of plasma cells with Russel bodies and amyloid. Local excision or lobectomy has been curative in most cases.
