Background : Primary malignant tumors of the trachea are extremely rare entities and account for a mere 0.1 per cent of all malignancies of the respiratory tract. Because of vague localizing signs, symptoms and a usually negative routine chest film, the patients with tracheal tumors are often treated for asthma or chronic obstructive pulmonary disease for considerable period of time before correct diagnosis. Method : We have made a review of the 17 cases of primary tracheal tumors in recent 15 years. We reviewed the clinical features including history of smoking and respiratory symptoms, the official readings of initial routine chest film, the cytologic examination of sputum, the time of delay in diagnosis, and the response according to the therapeutic modalities. Results : Eight out of 9 patients with squamous cell carcinoma(SCC) were above 50 years old, five out of 6 patients with adenoid cystic carcinoma(ACC) were below 50 years old. The most common location of primary tracheal tumors was the upper one-third of trachea in 8 cases(47%). The most frequent symptoms were dyspnea in 13/17 cases(76%) and then stridor or wheezing, cough. and sputum in order. The routine chest roentgenographic examinations were not helpful to diagnose tracheal carcinoma and the cytologic examinations of sputums were helpful to diagnose tracheal carcinoma in only one case with adenocarcinoma. The mean times of delay in diagnosis of patients with sec and ACC were 5 months and 24.9 months respectively. We had bronchial asthma in 8 cases(47%) and tracheal tumors in 4 cases(23%) as initial clinical impression. Conclusion : We would like to perform more comprehensive diagnostic tools(high KVP technique, the fibroptic bronchoscopic examination, chest CT scan etc.) in patients who had the suggestive points for the tracheal tumorse(1. unexplained hemoptysis or hoarsness, 2. inspiratory wheezing or stridor, 3. wax and waning of dyspnea according to changes of position, 4. progressive asthmatics unresponsive to antiasthmatic therapy) and radical resection of tumor or external radiation therapy with curative aim as possible.

Carinal resection is technically demanding and the surgical risk is relatively high. When tumor is confined around the carina, then lung parenchymal sparing surgery is technically feasible in selected cases. We performed carinal resection and reconstruction without pulmonary resection for a patient suffering with squamous cell carcinoma that involved the carina and this patient had undergone right upper lobectomy 19 months previously due to lung cancer.

경부기도의 종양은 편평상피암과 함께 이비인후과의에게 있어서 호흡곤란 환자의 감별진단을 위해 매우 중요한 임상적 의미를 갖는다. 종양은 암종에 의한 사망률의 0.1%이하를 차지하는 드문 질환이며 선양낭성암종은 기도의 원발성 종양중 두 번째로 많은 질환이다. 갑상선종양의 기도의 직접적인 침범이 흔히 발견되는 상태이며, 그다음으로 편평상피암, 선양낭성암종이 기도의 원발성 종양으로 흔한 질환이다. 갑상선의 악성종양이 기도의 벽이나 내강을 침입하는 것과 마찬가지로, 기도의 원발성 악성종양도 흔히 갑상선을 침범하여 갑상선의 종괴처럼 발현할 수 있다. 본 연구는 이와 같이 갑상선의 악성종양과 유사한 임상경과를 보이는 기도의 선양낭성암종의 향후 감별진단을 위해 4명의 조직학적으로 증명된 갑상선을 침범하는 기도의 선양낭성암종환자의 임상기록과 전산화 단층촬영소견을 후향적으로 관찰하였다. 전산화 단층촬영에서 이들은 기도에 넓은 기저부를 가지고 갑상선을 밀고있는 균일한 음영의 일반적으로 부드러운 경계를 가지는 종괴로 보였으며, 횡단면과 두정면에서 모두 기도 벽의 비후소견을 보였다. 이러한 소견은 기도의 원발성 선양낭성암종의 감별에 도움이 될 것으로 생각된다.

Endoscopic removal is acceptable for the treatment of endotracheal/endobronchial mass, because it is less invasive in high-risk patients and a conservative procedure for benign tumors. Two benign tumors in the lumen of the trachea (pure lipoma) and in the intermediate bronchus (hamartoma) were completely eradicated by our procedures, which involved diathermic snaring and residual mass removal with biopsy forceps under the guidance of fiberoptic bronchoscopy. No tumor recurrence was evident after extended follow-up (6 years for endotracheal lipoma and 2.5 years for endobroncheal hamartoma). Our method is safe and less invasive for the patient and provides the surgeon with better view during procedure.

Leiomyoma of the bronchus is a very rare, benign tumor of the lung. We herein report a case of endobronchial leiomyoma which was treated by sleeve bronchoplasty without resection of the lung and without any complications. A 35-year-old man was admitted to our hospital complaining of stridor. Bronchoscopy revealed a round, hypervascular and smooth tumor nearly obstructing the left main bronchus at 1.5 cm distal portion from the carina. Biopsy was not performed for fear of massive hemorrhage. A sleeve resection of left main bronchus including the tumor and end-to-end anastomosis were performed. The histologic diagnosis was leiomyoma. The early diagnosis and appropriate surgical treatment to preserve the pulmonary function are important points of consideration.

Pure lipoma, originating from the trachea is a very rara disease entity A-37-ycar-old-male patient had suf'leered from intermittent episodes of dyspnea and has been treated under the diagnosis of bronchial asthma for 6 months. On chest CT scan and bronchofiberscopic examination, a round mass with the pedunculated neck was found in the mid-portion of the membranous portion of the intrathoracic trachea. Under the guide of fiberoptic bronchoscope, the mass was extirpated using polypectomy w re loop and eletrocauterization . He was discharged without any events on third postoperative day of operation and has been well without recurrence for 6 months.

1972년 Jako와 Strong이 후두질환에 $CO_2$레이저 사용을 발표한 이래 최근 이비인후과영역에서 $CO_2$레이저를 이용한 수술방법이 각광을 받고 있으며 특히 후두 및 기관지 협착증에서의 $CO_2$레이저 이용은 현재까지 가장 좋은 방법의 하나로 소개되고 있다. 이와 더불어 최근 레이저를 이용한 기관지경술이 이용되고 있는데, 이는 기관 및 기관지의 여러 질환중에서 유두종등의 양성종양의 제거, 기관 및 기관지 협착증의 치료, 그리고 원발 혹은 전이에 의한 기관내 악성종양의 고식수술(姑息手術)등에 이용되고 있다. 최근 저자들은 성문하부 및 기관내에 발생한 후두 및 기관유두종 2례와 육아조직에 의한 성문하부 및 기관협착증 2례에서 coherent $CO_2$레이저 기관지경을 이용한 기관지경술로 만족할 만한 결과를 얻었기에 문헌고찰과 함께 보고하는 바이다.

신경초종은 비교적 드문 질환으로서1908년Verocay가 이 종양의 특징적 조직소견인 Verocay body를 발견하고 이를 neurinoma라고 명명하였다. 이 종양은 양성종양으로서 뇌신경, 척수신경뿐 아니라 자율신경에서도 발생하여, 약 25%가 두경부에서 발생하고, 단일 부위로서는 청신경에서의 발생빈도가 가장 높으나 인후부 발생은 드물다. 저자들은 피열후두개추벽에 발생한 거대한 신경초종 1례를 치험하였기에 보고하는 바이다.
