Adenoid cystic carcinoma usually grows in the trachea or near its bifurcation and causes obstruction of the air way. We recently experienced a 33 year-old male patient who had adenoid cystic carcinoma in the left main bronchus with the chief complaint of productive cough. On the bronchoscopy, the mass obstructed the left main bronchus completely and had nodularity and increased vascularity.The trachea was shifted to the left side and the lower lobe of the left lung was atelectatic on chest X-ray and computed axial tomogram.He underwent left tracheal sleeve pneumonectomy and lymph node dissection through bilateral thoracotomy. At first,we attempted left tracheal sleeve pneumonectomy through the left thoracotomy,however, it was very difficult to perform carinoplastic procedure after sleeve resection of 2.5cm of distal trachea and 1cm of proximal right main bronchus including whole left lung because of poor operative field and difficulty in the anastomosis of the right main bronchus to the distal end of the trachea without tension.Therefore after radical resection of the left lung we made right thoracotomy,through which we could anastomosed the distal trachea and right main bronchus with 4-0 PDS interrupted suture after mobilization of the right hilum without difficulty. The tumor was confirmed to be adenoid cystic carcinoma with metastasis to subcarinal lymph node histopathologically. Postoperative course was uneventful but he needed two bronchoscopic procedure to clear distal airway of the retained bronchial secretion. He was discharged at 14 days after operation with complete recovery.

Tumor of the trachea are uncommon. Trachea tumor are usually diagnosed late in their natural history, because the tracheal lumen may be extensively involved before symptoms occur, and because symptoms may be confused with those of asthma. Some 19% to 29% of the trachea tumor have laryngeal or lung malignancy. Squamous carcinoma is by far the most frequent among tracheal tumor, although adenocarcinoma and oat cell carcinoma have been described so. Oat cell carcinoma in the trachea are aggressive tumors as they are in the lung and elsewhere. Oat cell carcinoma as well as squamous cell carcinoma are related with tobacco exposure. We presented a case of small cell carcinoma nearly obstructing the trachea and right main bronchus which was partially removed after bronchoscopic ethanol injection, along with a review of the literature.

Adenoid cystic carcinoma of the tracea is rare, but is a very serious critical life-threatening disease.Nearly all the lesions of the trachea are presented as obstructive lesions. Bronchoscopic examination including chest CT, tomogram and air tracheogram are essential for the further definition of these lesions. This is a case report of adenoid cystic carcinoma in a 47 years old male patient. The tumor was located in cervical trachea with wide base and obstructing the lumen almost completely. The patient`s symptom was productive cough and hoarseness for 4 months. The tumor was resected and End-to-End anastomosed. The tumor was confirmed to be adenoid cystic carcinoma histopathologically. The need for removal of tracheal tumor whether complete or incomplete, is clear enough regardless of the histology of the tumor. This patient was treated post-operatively with radiation.

결론적으로 기관내 신경초종은 기관지 천식으로 오인되어 진단이 늦어질 수 있으나 특징적인 증상인 흡기시의 호흡곤란, 가변성 흉곽외 기도폐쇄의 소견을 보이는 폐기능 검사등으로 의심할 수있고, 기관 단층 촬영, 경부 컴퓨터 단층 촬영 및 기관지 내시경을 통해 쉽게 진단이 가능하다. 새로운 치료법으로 기관지경하 레이저 소작술로 완치될 수 있고, 이에 본원에서 경험한 1예를 보고하는 바이다.

서론: 기관내에 발생하는 과오종은 상기도폐쇄를 야기하는 매우 드문 질환이다. 이의 임상상은 기관지 천식이나 만성 기관지염 등의 내과적 질환과 유사하여 진단이 늦어지는 경우가 있다. 증례: 호흡곤란이 주소였던 65세 남자환자에서, 기관내 종괴를 관찰하였다. 종괴는 경직성 기관지내시경을 이용하여 성공적으로 제거되었고, 조직학적 검사상 과오종으로 확인되었다. 이후 환자의 증상은 매우 호전되었다. 결론: 기관내 과오종을 비롯한 여러 종양들은 기도폐쇄를 일으키는 여러 내과적 질환으로 혼동될 수 있다. 그러나 대부분 내과적 치료로는 효과를 기대하기 어렵고 수술적 치료를 요하므로, 이의 감별이 중요할 것으로 생각된다.

Background and Objectives : Sulfur dioxide gas is one of the major airborne Pollutants noxious to human in industrialized countries. The most vulnerable areas in the human respiratory system were the trachea and main bronchi and a gradient of decreasing damage was observed in the peripheral tracheobronchial tree. Induced functional alteration was increased mucosal permeability, and morphological changes were epithelial sloughing, intracellular edema, mitochondrial swelling, widened intercellular spaces, and ciliary cytoplamic extrusions. The laminins are a family of extracellular matrix glycoproteins localized in the basement membrane. Their primary role is cell-matrix attachment, but many additional biologic activities, including Promoting cell growth and migration, tumor growth and metastasis, wound repair, and graft survival, have been demonstrated. Materials and Methods : Histologic changes and expression of laminin in tracheal mucosa sacrificed at 1 day, 2 day, 3 day, 1 week, 2 weeks, and 3 weeks after continued SO2 exposure of 250 ppm for 30 minutes a day(to 7week) were studied in rats. In this study, mild immune reaction for laminin was noted at the apical cytoplasm of epithelial cells and basement membrane one day after a 7 week $SO_2$ exposure. The cilia and nucleoi of epithelial cells were normal and no immune reaction was noted in Goblet cells. The lamina propria of the tracheal tissue was infiltrated by monocytes and lymphocytes. Results : At 24 hours after exposure, all tracheal cells except Goblet cells revealed a mild immune reaction for laminin. No immune reactions were noted in the basement membrane. At 72 hours after exposure, mild or moderate immune reactions for laminin was seen in the tracheal cell cytoplasm. Irregular faint immune reaction for laminin was noted in the basement membrane. At 1 week after exposure, strong immune reaction for laminin was detected over all tracheal cells, and the basement membrane was seen clearly. At 2~3 weeks after exposure, strong immune reaction for laminin was seen in all tracheal epithelial cells except Goblet cells and a mild immune reaction was partly revealed in the basement membrane. Conclusion : Our study suggests that 502 produces histologic damage on the tracheal mucosa. Longer duration after exposure of $SO_2$ makes more progressive healing on the tracheal mucosa and increased immunoreactivity for laminin.

Benign tracheal tumors are less common than malignant tumors, but they are relatively more important because they are operable and curable. Neurilemmoma is originated from Schwann cells of nerve sheath, which are characterized by benign, solitary, and encapsulated mass. Tracheal neurilemmomas are extremely rare and reported only 21 cases in the world literature. Recently, we experienced a case of neurilemmoma which arose from the trachea of a 48-year-old female patient who complained of progressive dyspnea. The tumor mass was removed successfully through bronchoscopic and tracheal fissure approach. The final pathological diagnosis viewed under a microscope after H&E stain was a neurilemmoma in which Antoni type A and type B both existed.

Papillary thyroid carcinoma is known as its relatively high cure rate after surgical treatment. But invasion of the trachea by thyroid carcinoma is poor prognostic factor and the best management is en bloc surgical resection of the tumor invading the trachea. A 55-year-old man was diagnosed as papillary thyroid cancer with tracheal invasion. We treated the patient by total thyroidectomy with window resection of invading trachea followed by immediate reconstruction with sternohyoid muscle flap and tracheostomy. At 48 days after surgery, tracheostoma was closed and the patient had no functional complication by the surgical process. Until 10 months after surgery, there was no sign of recurrence and the patient led social life without any discomfort. We present this case with a review of the related literatures.

We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.

Primary neoplasms of the trachea are rare, but are a very serious critical life-threatening disease. Nearly all the lesions of the trachea are presented as obstructive lesions. Bronchoscopic examination including chest C-T, tomogram and air tracheogram are essential for the further definition of these lesions. The need for removal of tracheal tumors whether complete or incomplete, is clear enough regardless of the histology of the tumor. We have experienced 9 cases from Jan. 1965 to June, 1985. One patient with tracheal hamartoma was cured with complete resection through rigid bronchoscopy and another patient with fibrous histiocytoma was treated with re-excision and laser evaporation through superior mediastinotomy due to recurrence, 1 year later. The remaining patients were treated with mass excision or segmental resection and end-to-end anastomosis through collar incision and superior mediastinal sternotomy. The remaining two patients were operated with and segmental resection and end-to-end anastomosis of trachea using partial cardiopulmonary bypass. The histologic diagnosis were adenoid cystic Ca[5], fibrous histiocytoma[1], mucoepidermoid Ca[1]. hamartoma[1], anaplastic Ca.[1]. Three patients were treated post-operatively with radiation; with adenoid cystic Ca.[2] and anaplastic Ca.[1]. Their post-operative courses were uneventful during the follow-up from 2 months to 7 years.
