A 57 year old human immune virus(HIV)-positive male presented with a progressive dyspnea for 6 months. Chest CT showed multiple polypoid masses arising from upper tracheal wall. Bronchoscopic examination revealed that multiple large cauliflower-like polypoid tumors was obstructing tracheal lumen. They were diagnosed as multiple squamous papillomas and were removed by Nd:YAG laser photocoagulation and rigid bronchoscopic treatment. The tumors were histologically diagnosed as squamous papilloma infected with human papilloma virus(HPV) type 6 and 11 in in-situ hybridization. Rigid bronchoscopy might be safer and more efficient than flexible bronchoscopy for the treatment of multiple tracheal papillomatosis obstructing tracheal lumen because of easy establishment of airway patency and direct use of rigid bronchoscope itself for tumor resection.

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.

Objectives : The aim of this study was to evaluate the effectiveness and feasibility of coblation resection for the treatment of laryngotracheal disease. Methods : We conducted a retrospective review, evaluating 7 patients with laryngotracheal disease treated using coblator. Information collected included demographic data of the patients, diagnosis, size and location of the disease, procedure time, the number of previous operation, and the postoperative complication. Results : Among the etiology, granulation is most frequent (n=4), followed by recurrent repiratory papillomatosis (n=2) and tracheal stenosis (n=1). The location of lesions was peristomal area (n=2), glottis (n=2), subglottis (n=2) and mid-trachea. Coblation resection could remove the lesions completely and there was no significant complication including local burn, bleeding, and hypertrophic scar. The procedure time was shorter than the previous operation using $CO_2$ laser. Conclusion : Coblation resection is an effective and safe method for layngotracheal disease and can substitute the classic method such as $CO_2$ laser.
