Tracheal diverticulum is often diagnosed incidentally and, due to its rarity, there is no standard treatment. It is a benign entity, but has the potential to cause specific symptoms, such as chronic upper respiratory infection and chronic cough. Symptomatic tracheal diverticulum can be medically treated, but likelihood of recurrence is high. We report a case of surgical resection of symptomatic tracheal diverticulum to prevent recurrence.

Tracheal Stenosis after Tracheostomy Treated Successfully with Papillotome Electrocautery A 39-year-old woman presented with symptoms of dyspnea. Ten years previously, she had received a tracheostomy because of the decision to not continue taking an anticonvulsant drug. Presently, chest computed tomography showed diffuse stenosis and focal web at the cervical trachea. We performed bronchoscopy and found a two-thirds reduction of the upper trachea due to the web-like fibrotic stenosis. Papillotome electrocautery removed the stenotic lesion. Endobronchial electrocautery is a valuable tool with potential for therapy of an endobronchial obstructing airway lesion. We report this case to introduce the successful treatment with papillotome electrocautery.

Benign Tracheobroncheal tumor is a rare disease such as 1.9% of all tumor of pulmonary origin. Because clinical manifestation of benign tracheal tumor resembles that of broncheal asthma, these patients are usually treated in a way that used in broncheal asthma. Therefore, the diagnosis is delayed. We experienced a case of tracheal neurilemmoma that cured by bronchoscopic laser therapy. A 23-year-old woman visited our hospital because of progressing dyspnea especially during inspiration. She was treated with aminophylline and 2 agonist under the impression of bronchial asthma at a local clinic. But because the symptoms were not relieved and pulmonary function test revealed variable extrathoracic lesion, we conducted bronchoscopy and biopsy. There were $1.5{\times}2cm$ sized movable mass with stalk attached right anterior wall of bronchus. The biopsy result was neurilemmoma. Therefore we conducted bronchoscopic Laser therapy four times and the lesion disappeared in bronchoscopy and chest CT.

Tracheal papillomatosis is rare. When the disease starts during childhood, it usually appears to be self-limiting if properly managed. In adults, however, the disease sometimes runs a more protracted course with a higher risk of developing cancer. The tumors are derived from the tracheal surface epithelium and tracheal mucous glands and usually grow exophytically. Treatment has traditionally been with repeated endoscopic resection. However, in view of its viral origin, attempts have been made to control the disease with interferon. A 67 years-old man was presented with exertional dyspnea. He was treated for bronchial asthma at another hospital. There was no improvement in his symptom. He was referred to this hospital, and a bronchoscopic biopsy showed tracheal papillomatosis. He was undergone bronchoscopic laser therapy with symptomatic improvement.

In contrast to juvenile laryngeal papillomatosis, which occurs most often in children and teenagers and is usually self limited, soliatry papillomas in adults are one of uncommon tumors of airway, and have a higher incidence of cancer. They are caused by the respiratory infection of human papilloma virus(HPV). They could spread to more distal airways and have a tendency of recurrence after limited surgical excision. Recently endoscopic therapies such as Nd-YAG laser, electrocautery, and cryotherapy provide extremely effective treatment modalities. We report a case of solitary tracheal papillomas in a 48 year-old man who presented with cough, scanty hemoptysis, and functional evidence of central airway obstruction. He was successfully treated by a Nd-YAG laser therapy via fiberoptic bronchoscopy under the local anesthesia.

Hemangioma is benign tumor that represent an fail in development of the vascular system, network or retiform stage. As with hemangioma elsewhere, spontaneous regression may occur. Histologically capillary hemangioma has a diagnostic lobular arrangement of capillaries and almost all of them are located in nasal or oral mucous membranes. But, as we know, there is no report of hemangioma located in the trachea in Korea, so we report a case of tracheal hemangioma which was manifested massive hemoptysis.

Leiomyoma of the trachea is a very rare tumor, and the tracheal tumor is frequently misdiagnosed and treated as bronchial asthma. We report here a case of leiomyoma of the trachea which was successfully resected. A 40-year-old woman has sufferred from a repeated episode of asthmatic attack for two years. Intensive therapy for asthma had no beneficial effect on her respiratory symptoms, and wheezing and stridor did not disappear. Chest CT and bronchoscopy revealed a pedunculated mass on the trachea just above the carina. Wedge resection of the trachea and right main stem bronchus including the tumor and end-to-end anastomosis was performed. The result of the pathologic examination of the tumor was tracheal leiomyoma. Her postoperative course was uneventful and postoperative bronchoscopic findings showed clear healing of the anastomosis site.

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.

Primary pulmonary lymphoma is rare, especially lymphomas arising in and limited to the tracheal wall without pulmonary parenchymal involvement are extremely rare. Bronchus-associated lymphoid tissue (BALT) lymphoma accounts for the majority of tracheal lymphomas. BALT lymphoma reveals distinct clinicopathologic features and remains localized for prolonged periods. The diagnosis is made histopathologically. Optimal management of these rare lesions has not been established. But, chemotherapy and radiation therapy all have been tried with favorable short-time results. The prognosis of BALT lymphoma is relatively good. We present here a case of BALT lymphoma of the tracheal wall which had responded to bronchoscopic ND-YAG laser therapy and local radiation therapy.

Acquired tracheobronchial stenosis has resulted from vehicular accidents, prolonged tracheal intubation, sleeve resection, tuberculosis and sarcodosis. Various modalities of therapy for the relief of such stenosis included surgery, cryotherapy, laser photoresection, and sometimes balloon dilatation. Several recent reports have described the use of self-expandable metal stents for the dilatation of stenotic areas in the tracheobronchial tree. Three patients of benign acquired tracheobronchial stenosis were treated with self-expandable metal stents, who had shown little response to several times of balloon dilatations; One patient had a tracheal stenosis caused by intubation, one a right main bronchial stenosis developed after reconstructive surgery of traumatic bronchial rupture, and the other a left main bronchial stenosis caused by longstanding endobronchial tuberculosis. We found that the using stent in benign acquired tracheobronchial stenosis can be effectively performed with alleviation of clinical symptoms and lung function. And even in longstanding localized stenosis of main bronchus without distal bronchial destruction, lung perfusion also improved.
