To maintain an adequate airway in a patient with tracheobronchial narrowing coming from various causes, prosthetic tracheobronchial stents provide palliative treatment for narrowed airways where surgical resection is inadvisable. After insertion, previous reported complications were granuloma formation, dysphagia, suction catheter entrapment and fatal massive hemoptysis. We report, a case of complication associated with expandible metallic stent with endobronchial stenosis due to tuberculosis.

We experienced one case of endobronchial hamartoma on left lower lobar bronchus in sixty year old male patient. Less than 1 % of lung tumors are benign, and the prevalence of endobronchial hamartoma is reported to be from 3 % to 40 %. The mean age was 52.9 years, and equal gender prevalence.Symptoms were related to intraluminal growth, including fever, chill, productive cough, hemoptysis, exertional dyspnea, recurrent pneumonia and so on. Bronchoscopic finding was tumor present as polypoid mass in the lumen of a left main stem bronchus,distal to 3 cm from carina. Biopsy was done. The histopathologic pattern showed several nodules of loose myxoid tissue and islands of cartilage. We performed partial resection of the affected bronchus,1cm anterior to the superior segmental bronchial opening to just distal from superior segmental orifice. Including superior segmentectomy, partial resection of the left lower lobar bronchial resection and end-to-end anastomosis with 4-0 Poly dioxanone sutere materials interruptedly. We report this case with the brief review of literatures.

Foreign body aspiration occurs uncommonly in adults. A review of recent reports reveals only a few case reports on this topic. We have experienced 8 cases of endobronchial foreign bodies in adults from June 1988 to February 1991 which were removed successfully with fiberoptic bronchoscope and biopsy forceps. Only one of them had the primary disorder predisposing aspiration. Foreign bodies were located in right lower lobe (3 cases), right intermediate (2 cases), left lower lobe (2 cases) and left upper lobe bronchus (1 cases). Removal of endobronchial foreign boides in adult would be accomplished by fiberoptic bronchoscopy successfully.

Endobronchial ultrasound guided transbronchial needle aspiration is a recently introduceddiagnostic method which enables real time aspiration of peritracheal and peribronchial lesions. The high sensitivity and the high diagnostic accuracy of EBUS-TBNA in the mediastinal staging of lung cancer have been reported. EBUS-TBNA also showed the high diagnostic yield in the diagnosis of lung parenchymal masses adjacent to the trachea or the large airways. EBUS-TBNA is a good diagnostic method for mediastinal diseases, such as sarcoidosis. Until now, no major complications of EBUS-TBNA have been reported. EBUS-TBNA should be considered for the mediastinal staging of lung cancer and the diagnosis of mediastinal lymphadenopathies.

Pulmonary hamartoma has been considered as rare disease, which consists of lung tumor less than 1 %. Originally described by Albrecht in 1904, hamartoma is tumor like malformation-abnormal mixing of the normal components of organ-and is applied also to tumor found in many organs other than the lung. Lately, the major conclusions are that pulmonary hamartoma is neoplastic rather than developmental error in origin. Because pulmonary hamartoma frequently mimics lung cancer, especially in cancer-risk age groups, its clinical significance is great. Recently, we experienced 1 cases of endobronchial hamartoma which located at the right main stem bronchus. The patient was a 54 year old male who was admitted due to symptoms of fever 4 chilliness and dyspnea. Radiologic studies such as chest x-ray, chest tomogram and chest C-T scan revealed that the nearly total haziness of the right lung was caused by endobronchial tumor. The mass was considered as a benign by bronchoscopic exam, so we removed it surgically by tracheobronchotomy without pulmonary resection. Postoperative chest x-ray revealed satisfactory reexpansion of previous collapsed right lung. The patient discharged uneventfully.

Primary endobronchial leiomyosarcoma is a very uncommon tumor and its diagnosis by spontaneous expectoration of tumor fragment has never been reported in the literature. We report a patient with primary endobronchial leiomyosarcoma that was diagnosed by spontaneous expectoration of partial tumor tissue. The expectorated tissue was found to be pathologically consistent with leiomyosarcoma. Right lower lobectomy and all lymph node dissections were performed during the operation. Pathologic examination showed that the tumor was histologically identical to the patient's previous expectorated tissue and was confined to the bronchus and did not invade the adjacent pulmonary parenchyma and lymph nodes.

Carcinosarcoma of the lung is a rare turner with an admixture of malignant epithelial(carcinomatous) and malignant mesenchymal (sarcomatous) components. Clinicopathologically, pulmonary carcinosarcoma has been divided into two types by its anatomical locations and growth nature, peripheral parenchymal and central endobronchial variants. We experienced an endobronchial carcinosarcoma that induced complete atelectasis of the right lung due to polypoid growing mass from the right upper lobe bronchus in a 67 year old male smoker. The patient underwent a successful right pneumonectomy. The tumor was composed of squamous cell carcinoma with variable sarcomatous differentiation into myogenous and undifferenciated sarcoma that demonstrated by immunohistochemical study. The patient has been doing well for the last seven months since the operation, without metastases or turner recurrence.

Background: Endobronchial tuberculosis is classified into 7 subtypes as fibrostenotic type, edematous-hyperemic type, actively caseating type, tumorous type, ulcerative type, granular type and nonspecific bronchitic type by bronchoscopic features, and we make a prospective study to follow up how bronchoscopic findings change during treatment-course in each subtype of active endobronchial tuberculosis. Methods: We planned to do follow-up bronchoscopic examination every month until there was no significant change in endobronchial lesion, then every 3 months and at the end of the treatment in each patient with biopsy proven endobronchial tuberculosis from May, 1990 to August, 1993. Results: 1) This study included 66 cases, but bronchoscopic follow-up was completed as scheduled in 47 cases. 2) In actively caseating and edematous-hyperemic type, bronchostenosis occurred within 2 or 3 months of treatment in about 2/3 of total cases. 3) In fibrostenotic type, bronchostenosis did not improve in spite of the treatment. 4) In tumorous type, the changes in bronchoscopic findings were unpredictable because new lesions occured on other sites even 4 or 6 months after treatment in 2 cases and the size of initial mass increased 6 months after treatment in 1 case (among 7 cases). 5) Granular and nonspecific bronchitic type improved without significant sequelae within 2 or 3 months of treatment. Conclusion: It may be necessary to follow up the patient with bronchoscopy repeatedly 2 or 3 months after starting treatment in active endobronchial tuberculosis, and it is better to perform bronchoscopic examination at 6 months of treatment, especially in patients with tumorous type because there is possibility that new endobronchial lesion occurs. Aggressive therapeutic modalities such as stent-insertion, laser therapy or electrocautery should be considered to prevent bronchostenosis in cases with granulation tissue, fibrostenotic and tumorous types of endobronchial tuberculosis.

Background: Endobronchial tuberculosis is one of the serious complications of pulmonary tuberculosis. Without early diagnosis and proper treatment of endobronchial tuberculosis, bronchostenosis can leave and lead to the collapse of distal lung parenchyme, bronchiectasis, and secondary pneumonia accompanied with moderate to severe dyspnea, cough, hemoptysis, and localized wheezing. Therefore steroid therapy has been tried to prevent bronchostenosis. But the effect of steroid therapy on the endobronchial tuberculosis is not definite at present. We tried to elucidate the effect of steroid on the treatment of endobronchial tuberculosis for prevention of bronchostenosis. Methods: We observed the initial and sequential bronchoscopic findings, pulmonary function tests and simple chest roentgenograms in 58 patients diagnosed as endobronchial tuberculosis and admitted to Chung-Ang university hospital from 1988 to 1992. The patients in nonsteroid group (n=39) were treated with anti-tuberculosis chemotherapy only and steroid group(n=17) with combined steroid therapy. Sequential bronchoscopic findings, pulmonary function tests, and chest roentgenograms were comparatively analyzed between the two groups. Results: 1) The endobronchial tuberculosis was highly prevalent in young females especially in third decade. 2) Both actively caseating type and the stenotic type without fibrosis was the most common in the bronchoscopic classification. 3) The sequential bronchoscopic findings in steroid group 2 months after treatment showed no significant improvements compared with nonsteroid group. 4) There was no significant difference between the two groups in the sequential bronchoscopic improvements according to bronchoscopic types. 5) We did not find any significant difference in improvements on follow-up pulmonary function tests and simple chest roentgenograms between the two groups 2 month after treatment. 6) There was no significant adverse effect of steroid during the treatment. Conclusion: Combined steroid therapy provably would not influence outcome of the treatment of endobronchial tuberculosis.
