Aspiration of foreign bodies into the tracheobronchial tree is unusual in adults and it may result in Proximal airway obstruction and acute life-threatening asphyxia. It can be diagnosed by history of aspiration or visualizing the foreign body by chest roentgenogram or bronchoscopy. But it is rarely considered in adults with subacute or chronic respiratory symptoms without a definite history which suggests an aspiration. A 70-year-old woman was admitted to the hospital due to productive cough for two months and dyspnea which aggravated since the day before admission. Chest X-ray showed Pneumonic infiltration on left upper lobe and right lower lobe. Despite several days of conventional therapy, the patient complained of severe dyspnea and wheezing. We performed chest CT to rule out endobronchial stenosis, and it revealed the narrowing of left main stem bronchus compatible with endobronchial tuberculosis. Fiberoptic bronchoscopy for confirmation disclosed a $3.2{\times}0.7{\times}0.2$cm sized foreign body located longitudinally at the left main stem bronchus. We removed it with alligator forcep and it proved In be a piece of artificial denture. The patient remembered losing it while severe coughing on the day before admission. The microscopic examination of bronchial washing fluid revealed numerous acid fast bacilli. After removal of the foreign body, the patient showed marked improvement in symptom and pulmonary function test. Here we report a case of Pulmonary aspiration of foreign body which is confused with endobronchial tuberculosis with a review of the literature.

A bronchial adenoma. being one of rare neoplastic diseases in children, was reported in a 4 year-old-male child. The tumor was located entirely intraluminal in the left main bronchus and was treated with left pneumonectomy because of the irreversible cystic changes were revealed throughout the left lung on open thoracotomy. The tumor was histologically confirmed to be a muco-epidermoid type of bronchial adenoma.

The mucoepidermoid carcinoma of the bronchus is very rare neoplasm. The histological appearance is an intimate mixture of mucous-producing cell and epidermoid cell. The malignant potency of the tumor was determined by histologic pattern. Bronchoplasty techniques represent the ideal form of excisional therapy for benign endobronchial tumor as well as tumors of low-grade malignant potential, such as bronchial adenoma, and for repair of traumatic airway injuries and benign stricture and selected group of patients with carcinoma of the lung. We experienced a case of-low-grade mucoepidermoid carcinoma in a patient of 21-year old male who has been suffered from hemoptysis episodes for several years. The sleeve resection of left main bronchus and left lower lobectomy due to bronchiectatic change were carried out. The patient are being followed up without specific problem.

Benign papillary tumors commonly arise in the upper respiratory tract but are rare in the lower respiratory tract, especially in the bronchi. Solitary benign papillary tumors arising at the bronchi,covered with stratified squamous epithelium and associated with little or no inflammatory cell response,seem to be rarest of all types of benign bronchial tumors. Only six cases of such tumors had been reported in the medical literature over the past 74 years until 1968. The following is a case report of solitary benign papilloma arising at the opening of the left main bronchus which was treated with bronchoscopic removal at Chest Surgery Depariment, N.M.C. on Sept.

Mucoepidermoid carcinoma of the lung is a very rare and potentially malignant tumor that arises from submucosal gland of the trachea and bronchi. We experienced two cases of mucoepidermoid carcinoma which was located in the left main bronchus and right intermediate bronchus. They were treated with left sleeve resection and right bilobectomy. Postoperative course was uneventful, and the followed up for each of them was 3 year and 18 months without any evidence of recurrence.

Adenoid cystic carcinoma is an uncommon histologic variant of adenocarcinoma which usually arises from the salivary, lacrimal, or other exocrine glands. Characteristics of adenoid cystic carcinoma are its potential for extending long distance submucosally and for perineural invasion. It grows slowly and may have a prolonged course before diagnosis and after treatment. Recently, we have experienced 2 cases of adenoid cystic carcinoma arising from main bronchus and trachea. One case was 58 years old female patient. Her symptoms were productive cough with dyspnea. She has been history of shortness of breath, wheezing and cough during 4 years, which was initially diagnosed as bronchial asthma. The tumor was located on the left main stem bronchus which was obstructed the lumen nearly complete, by CT demonstration. Tissue diagnosis was confirmed as adenoid cystic carcinoma by bronchoscopic biopsy. The patient underwent radiation to relieve a bronchial stenosis caused by her tumor. The patient has remained well and is asymptomatic without evidence of clinical recurrence. The other case was 25 year old female. She complained shortness of breath and inspiratory difficulty during sleep. The tumor was located in upper trachea, which protruded from the posterior wall of the trachea and obstructed the lumen nearly complete, by CT demonstration. Tissue diagnosis was confirmed as adenocystic carcinoma by rigid bronchoscopic biopsy. The patient was underwent operation for removal of the mass and received radiotherapy. The patient has remained well are following up now.

An 18-year-old woman was evaluated for a chronic productive cough and dyspnea. She was subsequently diagnosed with mediastinal non-Hodgkin lymphoma (NHL). A covered self-expandable metallic stent (SEMS) was implanted to relieve narrowing in for both main bronchi. The NHL went into complete remission after six chemotherapy cycles, but atelectasis developed in the left lower lobe 18 months after SEMS insertion. The left main bronchus was completely occluded by granulation tissue. However, the right main bronchus and intermedius bronchus were patent. Granulation tissue was observed adjacent to the SEMS. The granulation tissue and the SEMS were excised, and a silicone stent was successfully implanted using a rigid bronchoscope. SEMS is advantageous owing to its easy implantation, but there are considerable potential complications such as severe reactive granulation, stent rupture, and ventilation failure in serious cases. Therefore, SEMS should be avoided whenever possible in patients with benign airway disease. This case highlights that SEMS implantation should be avoided even in malignant airway obstruction cases if the underlying malignancy is curable.

Primary endobronchial leiomyosarcoma is extremely rare, which is uncommon of primary endobronchial tumors. We report a primary endobronchial leiomyosarcoma. A 19-year-old male patient was admitted to the hospital ulcerative endobrochial tumor in the origin of left lower lobar bronchus and bronchoscopic biopsy showed a endobronchial leiomyoma. The patient underwent a left lower sleeve lobectomy and final pathologic diagnosis was ㅁ primary endobronchial leiomyosarcoma. After 4 months, follow-up bronchoscopy reveled local recurrence of a endobronchial leiomyosarcoma on a left main bronchus. A left completion pneumonectomy was perfomed and he was discharged without complications.

We have performed four left lung reimplantation and right pulmonary artery ligation in dogs for six months from March 1989 to September 1989 at the Thoracic & Cardiovascular Surgery department, Yonsei University, College of Medicine, Seoul, Korea. Excised left lungs were perfused with 200cc of 4oC cold saline at a pressure of 60cmH2O through left pulmonary artery & preserved in 4 oC cold saline for about 20 mins. Left lung reimplantation were proceeded with inferior pulmonary vein, superior pulmonary vein, left pulmonary artery and left main bronchus in order. The main pulmonary artery pr. were 39/21[31], 22/12[15], 25/9[15] and 54/17[37] mmHg each after right pulmonary artery ligation on left reimplanted dogs, Right pul a. ligations were performed 9 days, 12 days, 16 days and 19 days after left lung reimplantation. Two dogs died at 10 days 21 days, after right pul. a. ligations in left reimplanted dogs. The remaining two dogs were sacrificed at 18 days, 21 days after right pul. a. ligation in left reimplanted dogs. Autopsy findings showed narrowing of left superior pul. vein anastomotic site in two narrowing of left pulmonary artery anastomotic site in one narrowing of left sup. pul vein & pneumonia of left lung in one. In the lung transplantation, it was thought to be important that the anastomosis of pulmonary artery and especially pulmonary vein be done with particular precaution for early and late stenosis.

We experienced plastic reconstruction of tuberculous bronchostenosis with patient`s rib cartilage. He suffered from coughing and sputum for 2months, and was treated for pulmonary tuberculosis 10 years ago. In preoperative bronchoscopy, left main bronchus was fibrotic obstructive and LUL bronchus was severely destructed. After thoracotomy, we harvested the rib cartilage at the 6th rib, and designed semicircular and tubular graft. And then onlayed the graft over the longitudinal bronchotomy site by simple interrupted sutures with 4-0 Vicryl Postoperative course was good, coughing and sputum disappeared. In postoperative bronchoscopy, the patch graft was good in that position, and the internal diameter was sufficient, but the granuloma was found in the stoma of LUL bronchus. He was discharged without any other event.
